SY0-701 CompTIA Security+ Exam 2025 Question and Answers

Abug bounty programencourages ethical hackers tofind and report vulnerabilities, helping organizations discover security flaws before they are exploited by malicious actors. Unlikevulnerability scans, bug bounty programs usereal-world testing techniques.

A red team is a group of security professionals who perform offensive security assessments covering penetration testing and social engineering. A red team simulates real-world attacks and exploits the vulnerabilities of a target organization, system, or network. A red team aims to test the effectiveness of the security controls, policies, and procedures of the target, as well as the awareness and response of the staff and the blue team. A red team can be hired as an external consultant or formed internally within the organization. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 18.

Detective controls (such as audit logs, monitoring, and alerts) are specifically designed to identify and reveal unauthorized or malicious activity, including insider manipulation, in systems like payroll. These controls help ensure that any attempts to manipulate data are discovered and investigated.

Job rotation is a strategy used in organizations to detect and prevent fraud by periodically assigning employees to different roles within the organization. This approach helps ensure that no single employee has exclusive control over a specific process or set of tasks for an extended period, thereby reducing the opportunity for fraudulent activities to go unnoticed. By rotating roles, organizations can uncover irregularities and discrepancies that might have been concealed by an employee who had prolonged access to sensitive functions. Job rotation also promotes cross-training, which can enhance the organization's overall resilience and flexibility.

A hot site is a fully operational offsite facility that is equipped with hardware, software, and up-to-date data, and is ready to take over operations immediately if the primary site fails. This allows for minimal downtime and quick failover, meeting the requirement for rapid recovery.

Centralized authentication (such as Active Directory or LDAP) combined with proper password policies helps prevent the reuse of the same local credentials across multiple systems, reducing the risk of lateral movement during attacks like credential reuse or pass-the-hash.

A Statement of Work (SOW) is a formal document detailing the scope, deliverables, timeline, and estimated hours for services such as penetration testing engagements.

BPA (Blanket Purchase Agreement) covers recurring purchases, SLA (Service Level Agreement) defines service quality expectations, and NDA (Non-Disclosure Agreement) protects confidentiality, none of which specify hours or detailed scope.

SOWs are fundamental in managing third-party risk and engagements, covered under Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】.

The Online Certificate Status Protocol (OCSP) is a technology designed to check the revocation status of digital certificates in real-time without requiring the client to download entire revocation lists. Unlike Certificate Revocation Lists (CRLs), which are periodically updated and can be large, OCSP queries an OCSP responder to receive the status of a specific certificate.

OCSP is considered passive verification because it allows clients to check a certificate's current validity status on-demand without maintaining local copies of revocation data. The OCSP responder returns whether the certificate is valid, revoked, or expired.

Trusted Platform Module (TPM) is hardware for secure key storage, and Certificate Signing Request (CSR) is a request for certificate issuance; neither is used for verifying certificate expiration status.

The differences and roles of OCSP and CRLs are thoroughly covered in the Cryptography and PKI chapter of the SY0-701, where OCSP is highlighted as the more efficient and real-time method to verify certificate status passively【6:Chapter 7†CompTIA Security+ Study Guide】.

Upgrading end-of-support operating systemsisone of the most effective ways to reduce the attack surface. Unsupported OS versionsno longer receive security patches, making them prime targets for attackers.Removing outdated softwareensures that known vulnerabilities cannot be exploited.

A (honeynet)is used for threat analysis, not reducing the attack surface.

B (Group Policy)helps enforce security policies butdoes not address outdated vulnerabilities.

C (High availability)focuses on uptime, not security risk reduction.

When conducting a forensic analysis after an incident, it's essential to prioritize the data collection process based on the "order of volatility." This principle dictates that more volatile data (e.g., data in memory, network connections) should be captured before less volatile data (e.g., disk drives, logs). The idea is to preserve the most transient and potentially valuable evidence first, as it is more likely to be lost or altered quickly.

 The data plane, also known as the forwarding plane, is the part of the network that carries user traffic and data. It is responsible for moving packets from one device to another based on the routing and switching decisions made by the control plane. The data plane is a critical component of the Zero Trust architecture, as it is where most of the attacks and breaches occur. Therefore, implementing Zero Trust principles within the data plane can help to improve the security and resilience of the network.

One of the key principles of Zero Trust is to assume breach and minimize the blast radius and segment access. This means that the network should be divided into smaller and isolated segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot easily move laterally to other segments and access more resources or data. This principle is also known as threat scope reduction, as it reduces the scope and impact of a potential threat.

The other options are not as relevant for the data plane as threat scope reduction. Secured zones are a concept related to the control plane, which is the part of the network that makes routing and switching decisions. Subject role is a concept related to the identity plane, which is the part of the network that authenticates and authorizes users and devices. Adaptive identity is a concept related to the policy plane, which is the part of the network that defines and enforces the security policies and rules.

Zero-day vulnerabilities are unknown flaws in software, making them harder to patch, especially when using open-source libraries without dedicated support teams.

=================

Detective controls are security measures that are designed to identify and monitor any malicious activity or anomalies on a system or network. They can help to discover the source, scope, and impact of an attack, and provide evidence for further analysis or investigation. Detective controls include log files, security audits, intrusion detection systems, network monitoring tools, andantivirus software. In this case, the administrator used log files as a detective control to review the ransomware attack on the company’s system. Log files are records of events and activities that occur on a system or network, such as user actions, system errors, network traffic, and security alerts. They can provide valuable information for troubleshooting, auditing, and forensics.

A Security Information and Event Management (SIEM) solution collects, aggregates, and correlates logs from multiple sources to detect anomalies and generate alerts. SIEMs are essential for security monitoring and incident detection.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.

This describes a watering hole attack, where an attacker compromises a website frequently visited by the target group and delivers malicious payloads, such as automatic downloads.

XSS (A) injects scripts into web pages, typosquatting (C) involves fake websites with misspelled URLs, and buffer overflow (D) exploits memory but does not involve website compromise with automatic downloads.

Watering hole attacks are well-known web-based threats covered in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

A brute-force attack is a type of attack that involves systematically trying all possible combinations of passwords or keys until the correct one is found. The log file shows multiple failed login attempts in a short amount of time, which is a characteristic of a brute-force attack. The attacker is trying to guess the password of the Administrator account on the server. The log file also shows the event ID 4625, which indicates a failed logon attempt, and the status code0xC000006A, which means the user name is correct but the password is wrong. These are indicators of compromise (IoC) that suggest a brute-force attack is taking place. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215-216 and 223 1

The first step in reducing the number of credentials each employee must maintain when using multiple SaaS applications is to select an Identity Provider (IdP). An IdP provides a centralized authentication service that supports Single Sign-On (SSO), enabling users to access multiple applications with a single set of credentials.

Enabling SAML would be part of the technical implementation but comes after selecting an IdP.

OAuth tokens are used for authorization, but selecting an IdP is the first step in managing authentication.

Password vaulting stores multiple passwords securely but doesn't reduce the need for separate logins​​.

The act described is espionage, where classified information is stolen and provided to adversaries or unauthorized parties, usually for political, military, or strategic advantage.

Data exfiltration (B) is the technical act of stealing data but doesn’t specify motivation. Financial gain (C) or blackmail (D) could be motivations but are not clearly indicated here.

Espionage is a classic threat actor motivation outlined in the Threats domain【6:Chapter 2†CompTIA Security+ Study Guide】.

Full Disk Encryption (FDE) ensures that all data on the drive is encrypted, preventing unauthorized access even if the device is lost.

=================

Virtualization (D)allows multiple systems and services to be hosted onfewer physical machines, therebyreducing the total number of physical devicesand consequently thehardware attack surface. This also allows for better patching, monitoring, and control.

The fewer devices you manage physically, the fewer entry points there are for attackers to exploit hardware-level vulnerabilities.

To mitigate the risk of confidential documents being left unattended in Multi-Function Printers (MFPs), implementing an authentication factor that requires in-person action before printing (such as PIN codes or badge scanning) is the most effective measure. This ensures that documents are only printed when the authorized user is present to collect them, reducing the risk of sensitive information being exposed.

Encryption is a reversible process that transforms cleartext data into ciphertext to protect confidentiality. It uses cryptographic keys to both encrypt and decrypt data, ensuring that only authorized parties can access the original data.

Hashing, on the other hand, is a one-way function that converts data into a fixed-length hash value or checksum. Hashing is primarily used to verify data integrity by detecting changes, since any modification in the input will produce a different hash output. Unlike encryption, hashing cannot be reversed to obtain the original data.

While encryption can protect data both at rest and in transit, hashing does not protect data confidentiality but supports integrity verification. Public-key exchange is a cryptographic mechanism within asymmetric encryption but is unrelated to hashing key usage.

This distinction is thoroughly explained in the Cryptography chapter of the SY0-701 syllabus【6:Chapter 7†CompTIA Security+ Study Guide】.

A jump server is a device or virtual machine that acts as an intermediary between a user’s workstation and a remote network segment. A jump server can be used to securely access servers or devices that are not directly reachable from the user’s workstation, such as database servers. A jump server can also provide audit logs and access control for the remote connections. A jump server is also known as a jump box or a jump host12.

RADIUS is a protocol for authentication, authorization, and accounting of network access. RADIUS is not a device or a method to access remote servers, but rather a way to verify the identity and permissions of users or devices that request network access34.

HSM is an acronym for Hardware Security Module, which is a physical device that provides secure storage and generation of cryptographic keys. HSMs are used to protect sensitive data and applications, such as digital signatures, encryption, and authentication. HSMs are not used to access remote servers, but rather to enhance the security of the data and applications that reside on them5 .

A load balancer is a device or software that distributes network traffic across multiple servers or devices, based on criteria such as availability, performance, or capacity. A load balancer can improve the scalability, reliability, and efficiency of network services, such as web servers, application servers, or database servers. A load balancer is not used to access remote servers, but rather to optimize the delivery of the services that run on them . References =

In this scenario, employees are attempting to navigate to spoofed websites, which is being blocked by the web filter. To address this issue, the administrator should implement security awareness training. Training helps employees recognize phishing and other social engineering attacks, reducing the likelihood that they will attempt to access malicious websites in the future.

Deploying multifactor authentication (MFA) would strengthen authentication but does not directly address user behavior related to phishing websites.

Decreasing the level of the web filter would expose the organization to more threats.

Updating the acceptable use policy may clarify guidelines but is not as effective as hands-on training for improving user behavior​​​.

Theprimary goal of corrective controls in financial systems is to ensure that errors do not propagate across interconnected systems. Financial transactions are ofteninterdependent, meaning one incorrect or unauthorized change can affect multiple systems. Regulations often mandate these controls tomaintain accuracy and prevent cascading failures.

A (insider threats altering banking details)is a concern, but thisscenario focuses on corrective controls, not insider threats specifically.

C (business insurance)is unrelated to why corrective controls are implemented.

D (preventing unauthorized changes)falls underpreventive, notcorrectivecontrols.

ALE (Annualized Loss Expectancy) is the risk management metric most helpful when deciding whether the licensing cost of a ransomware prevention solution is justified. ALE calculates the expected yearly financial loss from a particular threat. It is computed as:

ALE = SLE × ARO

SLE (Single Loss Expectancy) estimates the monetary impact of one ransomware incident.

ARO (Annualized Rate of Occurrence) estimates how often the incident is expected to happen each year.

By comparing ALE to the annual licensing cost of the new security solution, the organization can make a financially informed decision based on cost-benefit analysis. If ALE exceeds the solution’s cost, the purchase is justified.

RTO (C) relates to recovery time after outages, not cost justification. SLE (B) is only part of the calculation and insufficient alone. ARO (D) shows frequency but not financial impact.

Security+ SY0-701 highlights ALE as the primary metric for evaluating security investments.

Thus, ALE is the key factor in determining whether purchasing ransomware protection is financially beneficial.

Automatically generating WAF rules when applications are deployed is a hallmark of Infrastructure as Code (IaC). IaC allows infrastructure components—including firewalls, WAF policies, and load balancers—to be defined and deployed via code templates rather than manual configuration. In DevSecOps, IaC enables security controls to be embedded into deployment pipelines, ensuring that protections such as WAF rules are created instantly and consistently whenever new application versions are released.

Security+ SY0-701 highlights IaC as a method for automating infrastructure provisioning, standardizing security controls, and reducing configuration drift. This allows development and security teams to collaborate more effectively by treating security policies as code.

IoT (B) refers to smart devices, IoC (C) refers to indicators of compromise, and IaaS (D) refers to cloud compute infrastructure—not automated security policy creation.

Thus, the correct answer is A: IaC.

Serverless architecture allows companies to deploy code without managing the underlying infrastructure. This approach significantly reduces the time and expense involved in code deployment because developers can focus solely on writing code, while the cloud provider manages the servers, scaling, and maintenance. Serverless computing also enables automatic scaling and pay-per-execution billing, which further optimizes costs.

CompTIA Security+ SY0-701 Course Content: The course covers cloud technologies, including serverless architectures, which are highlighted as a method to streamline and reduce costs associated with code deployment​​​.

The Annual Loss Expectancy (ALE) is most useful in determining whether the long-term cost to transfer a risk is less than the impact of the risk. ALE is calculated by multiplying the SingleLoss Expectancy (SLE) by the Annualized Rate of Occurrence (ARO), which provides an estimate of the annual expected loss due to a specific risk, making it valuable for long-term financial planning and risk management decisions.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

A web filter is a device or software that can monitor, block, or allow web traffic based on predefined rules or policies. One of the common methods of web filtering is to scan the URL for strings and deny access when matches are found. For example, a web filter can block access to websites that contain the words “gambling”, “porn”, or “malware” in their URLs. A URL is a uniform resource locator that identifies the location and protocol of a web resource. A URL typically consists of the following components: protocol://domain:port/path?query#fragment.The protocol specifies the communication method used to access the web resource, such as HTTP, HTTPS, FTP, or SMTP. The domain is the name of the web server that hosts the web resource, such as www.google.com or www.bing.com. The port is an optional number that identifies the specific service or application running on the web server, such as 80 for HTTP or 443 for HTTPS. The path is the specific folder or file name of the web resource, such as /index.html or /images/logo.png. The query is an optional string that contains additional information or parameters for the web resource, such as ?q=security or ?lang=en. The fragment is an optional string that identifies a specific part or section of the web resource, such as #introduction or #summary.

To prohibit access to non-encrypted websites, an analyst should employ a search string that matches the protocol of non-encrypted web traffic, which is HTTP. HTTP stands for hypertext transfer protocol, and it is a standard protocol for transferring data between web servers and web browsers. However, HTTP does not provide any encryption or security for the data, which means that anyone who intercepts the web traffic can read or modify the data. Therefore, non-encrypted websites are vulnerable to eavesdropping, tampering, or spoofing attacks. To access a non-encrypted website, the URL usually starts with http://, followed by the domain name and optionally the port number. For example, http://www.example.com or http://www.example.com:80. By scanning the URL for the string http://, the web filter can identify and block non-encrypted websites.

The other options are not correct because they do not match the protocol of non-encrypted web traffic. Encryption=off is a possible query string that indicates the encryption status of the web resource, but it is not a standard or mandatory parameter. Https:// is the protocol of encrypted web traffic, which uses hypertext transfer protocol secure (HTTPS) to provide encryption and security for the data. Www.*.com is a possible domain name that matches any website that starts with www and ends with .com, but it does not specify the protocol. :443 is the port number of HTTPS, which is the protocol of encrypted web traffic. References = CompTIA Security+ Study Guide (SY0-701), Chapter 2: Securing Networks, page 69. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 2.1: Network Devices and Technologies, video: Web Filter (5:16).

A honeytoken is a form of deception technology in which a fake asset (such as credentials, files, or database records) is planted in a system or network to detect unauthorized access or malicious activity. The fake password stored in a hidden spreadsheet, with monitoring for access, is a classic example of a honeytoken. It is not an interactive system (like a honeypot or honeynet) but rather a marker or tripwire intended to alert the security team to suspicious behavior. This method helps identify attackers and their methods early in the intrusion process.

Comprehensive and Detailed Explanation From Exact Extract:

The greatest advantage of network segmentation is the creation of security zones, which isolate systems into separate logical or physical network sections. According to CompTIA Security+ SY0-701, segmentation is a foundational security architecture practice used to reduce the attack surface, restrict lateral movement, enforce least privilege, and contain breaches. By dividing the network into zones—such as DMZ, internal, restricted, and guest—administrators can apply tailored access controls, firewall rules, IDS/IPS placement, and monitoring boundaries.

Segmentation provides defense-in-depth by preventing attackers from reaching critical systems even if they compromise a less-secure device. It also limits broadcast domains and improves traffic visibility. End-to-end encryption (A) protects confidentiality but is unrelated to segmentation. Decreased resource utilization (B) is not a primary benefit. Enhanced endpoint protection (C) applies to host controls, not network topology. Configuration enforcement (D) is a benefit of centralized management, not segmentation.

Therefore, the correct answer is Security zones, the core outcome and highest-value advantage of segmentation.

= A change control request is a document that describes the proposed change to a system, the reason for the change, the expected impact, the approval process, the testing plan, the implementation plan, the rollback plan, and the communication plan. A change control request is a best practice for applying any patch to a production system, especially a high-priority one, as it ensures that the change is authorized, documented, tested, and communicated. A change control request also minimizes the risk of unintended consequences, such as system downtime, data loss, or security breaches. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 6, page 235. CompTIA Security+ SY0-701 Exam Objectives, Domain 4.1, page 13.

Cyber insurance is a type of insurance that covers the financial losses and liabilities that result from cyberattacks, such as data breaches, ransomware, denial-of-service, phishing, or malware. Cyber insurance can help a company recover from the costs of restoring data, repairing systems, paying ransoms, compensating customers, or facing legal actions. Cyber insurance is one of the possible strategies that a company can use to address the items listed on the risk register. A riskregister is a document that records the identified risks, their probability, impact, and mitigation strategies for a project or an organization. The four common risk mitigation strategies are:

Accept: The company acknowledges the risk and decides to accept the consequences without taking any action to reduce or eliminate the risk. This strategy is usually chosen when the risk is low or the cost of mitigation is too high.

Transfer: The company transfers the risk to a third party, such as an insurance company, a vendor, or a partner. This strategy is usually chosen when the risk is high or the company lacks the resources or expertise to handle the risk.

Mitigate: The company implements controls or measures to reduce the likelihood or impact of the risk. This strategy is usually chosen when the risk is moderate or the cost of mitigation is reasonable.

Avoid: The company eliminates the risk by changing the scope, plan, or design of the project or the organization. This strategy is usually chosen when the risk is unacceptable or the cost of mitigation is too high.

By purchasing cyber insurance, the company is transferring the risk to the insurance company, which will cover the financial losses and liabilities in case of a cyberattack. Therefore, the correct answer is B. Transfer. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 377. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.1: Risk Management, video: Risk Mitigation Strategies (5:37).

Federation is an access management concept that allows users to authenticate once and access multiple resources or services across different domains or organizations. Federation relies on a trusted third party that stores the user’s credentials and provides them to the requested resources or services without exposing them. Password complexity is a security measure that requires users to create passwords that meet certain criteria, such as length, character types, and uniqueness. Password complexity can help prevent brute-force attacks, password guessing, and credential stuffing by making passwords harder to crack or guess. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308-309 and 312-313 1

Arace conditionoccurs whentwo or more processes attempt to access and modify a shared resource simultaneously, leading to unintended behavior. In this scenario, the attacker was able to modify a temporary fieldbefore the SQL update completed, indicating atime-of-check to time-of-use (TOCTOU) vulnerability, which is a type of race condition.

Memory injection (B)refers to inserting malicious code into a running process’s memory, but that isnotwhat is happening here.

Malicious update (C)is too broad and does not specifically describe this scenario.

Side loading (D)is a technique where malicious software is loaded via a trusted application, unrelated to this case.

Non-compliance with internal policies, such as corporate security policies, falls under internal non-compliance. These are rules created and enforced within the organization to maintain security standards.

External non-compliance (A) refers to violations of outside regulations or laws. Standards (B) are generally established best practices or industry guidelines, and regulation (C) refers to legal or governmental requirements.

Internal compliance management is a key focus area in the Security Program Management domain of SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Risk threshold is the maximum amount of risk that an organization is willing to accept for a given activity or decision. It is also known as risk appetite or risk tolerance. Risk threshold helps an organization to prioritize and allocate resources for risk management. Risk indicator, risk level, and risk score are different ways of measuring or expressing the likelihood and impact of a risk, but they do not describe the maximum allowance of accepted risk. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 34; Accepting Risk: Definition, How It Works, and Alternatives

A warm site offers a compromise between cost and recovery speed. It includes hardware and network infrastructure partially configured, allowing quicker recovery than a cold site but at lower cost than a hot site.

Hot sites (A) enable rapid recovery but at high cost. Cold sites (B) are low cost but slow to recover. Manual (C) refers to manual processes, typically slower.

Warm sites balance recovery time and cost in disaster recovery planning【6:Chapter 9†CompTIA Security+ Study Guide】.

Detailed Explanation:Privacy data includes information such as Personally Identifiable Information (PII), which relates to employees' or customers' personal data. Organizations often maintain policies and standards specifically addressing how such sensitive information should be handled. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Types and Classifications"​​.

Detailed Explanation:Load balancing improves application availability by distributing traffic across multiple servers. If one server fails, traffic is automatically routed to other available servers with minimal intervention. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "High Availability Solutions"​​.

Data exfiltration is a technique that attackers use to steal sensitive data from a target system or network by transmitting it through DNS queries and responses. This method is often used in advanced persistent threat (APT) attacks, in which attackers seek to persistently evade detection in the target environment. A large amount of unusual DNS queries to systems on the internet over short periods of time during non-business hours is a strong indicator of data exfiltration. A worm, a logic bomb, and ransomware would not use DNS queries to communicate with their command and control servers or perform their malicious actions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 487; Introduction to DNS Data Exfiltration; Identifying a DNS Exfiltration Attack That Wasn’t Real — This Time

The guidance focuses on attack surface reduction by eliminating unnecessary services, closing unused ports, and limiting publicly available information that attackers could leverage. Reducing the attack surface lowers the organization's exposure to threats and potential entry points.

Vulnerability assessments (B) identify weaknesses but do not necessarily involve active reduction measures. Tabletop exercises (C) simulate incidents, and business impact analysis (D) assesses the effects of disruptions, neither of which match the described activities.

Attack surface reduction is a core principle in Security Operations and penetration testing remediation strategies in SY0-701【6:Chapter 14†CompTIA Security+ Study Guide】.

SIEM stands for Security Information and Event Management. It is a security alerting and monitoring tool that collects system, application, and network logs from multiple sources in a centralized system. SIEM can analyze the collected data, correlate events, generate alerts, and provide reports and dashboards. SIEM can also integrate with other security tools and support compliance requirements. SIEM helps organizations to detect and respond to cyber threats, improve security posture, and reduce operational costs. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Monitoring and Auditing, page 393. CompTIA Security+ Practice Tests: Exam SY0-701, 3rd Edition, Chapter 10: Monitoring and Auditing, page 397.

Masking is a method to secure credit card data that involves replacing some or all of the digits with symbols, such as asterisks, dashes, or Xs, while leaving some of the original digits visible. Masking is best to use when a requirement is to see only the last four numbers on a credit card, as it can prevent unauthorized access to the full card number, while still allowing identification and verification of the cardholder. Masking does not alter the original data, unlike encryption, hashing, or tokenization, which use algorithms to transform the data into different formats.

Code signing (D)usescryptographic digital signaturesto confirm theintegrity and authenticityof software code. It ensures that the code hasnot been alteredafter being signed, providing assurance that the application is trustworthy.

This aligns withCompTIA Security+ SY0-701 Domain 2.3: Application security techniques, which includescode signingas a method to validatecode integrity.

Endpoint detection and response (EDR) is a technology that monitors and analyzes the activity and behavior of endpoints, such as computers, laptops, mobile devices, and servers. EDR can help to detect and prevent malicious software, such as viruses, malware, and Trojans, from infecting the endpoints and spreading across the network. EDR can also provide visibility and response capabilities to contain and remediate threats. EDR is different from IDS, which is a network-based technology that monitors and alerts on network traffic anomalies. EDR is also different from ACL, which is a list of rules that control the access to network resources. EDR is also different from NAC, which is a technology that enforces policies on the network access of devices based on their identity and compliance status. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 2561

Salting involves adding a unique value (salt) to each password before hashing it. This means that even if two users have the same password, the added salts ensure their hash values are different. This protects against attacks that exploit identical hash values, such as rainbow table attacks.

Sanitization is the process of thoroughly removing or wiping all data from devices before disposal or donation to prevent sensitive information from being recovered or leaked.

Orchestration is the process of automating multiple tasks across different systems and applications. It can help save time and reduce human error by executing predefined workflows and scripts. In this case, the systems administrator can use orchestration to create accounts for a large number of end users without having to manually enter their information and assign permissions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457 1

Shadow IT refers to employees using software or services without official approval, often introducing security risks due to lack of control, monitoring, or compliance. This can lead to vulnerabilities, data leakage, or policy violations.

Unskilled attacker (A) and hacktivist (B) are threat actor types; supply chain (D) refers to risks from external partners or vendors, not internal unauthorized software usage.

Shadow IT is highlighted in Security Program Management and Threats domains for its risk implications【6:Chapter 16†CompTIA Security+ Study Guide】.

A full inventory of all hardware and software is essential for measuring the overall risk to an organization when a new vulnerability is disclosed, because it allows the security analyst to identify which systems are affected by the vulnerability and prioritize the remediation efforts. Without a full inventory, the security analyst may miss some vulnerable systems or waste time and resources on irrelevant ones. Documentation of system classifications, a list of system owners and their departments, and third-party risk assessment documentation are all useful for risk management, but they are not sufficient to measure the impact of a new vulnerability. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1221; Risk Assessment and Analysis Methods: Qualitative and Quantitative3

A NAC (network access control) platform is a technology that enforces security policies on devices that attempt to access a network. A NAC platform can verify the identity, role, and compliance of the devices, and grant or deny access based on predefined rules. A NAC platform can protect both wired and wireless networks, but in this scenario, the systems administrator is trying to protect the wired attack surface, which is the set of vulnerabilities that can be exploited through a physical connection to the network12.

Packet capture data can be very large and may not need to be stored for extended periods compared to other logs essential for security audits.

=================

Purchasing insurance is a classic example of risk transfer, where financial risk associated with potential losses is shifted to a third party (the insurer). This strategy does not eliminate the risk but moves the financial burden.

Mitigation (A) reduces risk impact or likelihood through controls, acceptance (B) involves acknowledging the risk without action, and avoidance (C) eliminates the risk by not engaging in the activity.

Risk transfer is a fundamental concept taught in the Risk Management domain of SY0-701【6:Chapter 17†CompTIA Security+ Study Guide】.

Code signing uses digital signatures to verify software authenticity and integrity, ensuring the code has not been tampered with since it was signed by the developer. It helps detect if malware was introduced after delivery.

Static code analysis (B) inspects code for vulnerabilities during development but does not verify delivered binaries. Input validation (C) protects applications at runtime. Secure storage (A) protects stored data, unrelated to software delivery.

Code signing is an essential security control in Software Development Life Cycle and Supply Chain Security【6:Chapter 7†CompTIA Security+ Study Guide】.

"Network segmentation is a security practice that divides a network into smaller, isolated segments to limit access and reduce the attack surface. Firewalls are commonly used to enforce segmentation by creating rules that allow or deny traffic based on source, destination, and port. Tomeet compliance requirements, such as restricting access to internal servers, firewall rules can be configured to block all external traffic while permitting only authorized internal systems to communicate with the segmented servers. This ensures that sensitive resources are isolated from unauthorized access."

 Analysis is the incident response activity that describes the process of understanding the source of an incident. Analysis involves collecting and examining evidence, identifying the root cause, determining the scope and impact, and assessing the threat actor’s motives and capabilities. Analysis helps the incident response team to formulate an appropriate response strategy, as well as to prevent or mitigate future incidents. Analysis is usually performed after detection and before containment, eradication, recovery, and lessons learned. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 6, page 223. CompTIA Security+ SY0-701 Exam Objectives, Domain 4.2, page 13.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Incident Response and Containment"​​.

Change management procedures provide structured steps to approve, test, document, and deploy software changes, ensuring controlled and auditable version releases that minimize risks and disruptions.

Business continuity planning (A) relates to operational continuity, quantified risk analysis (B) assesses risks quantitatively, and static code analysis (C) finds coding defects but does not control release processes.

Change management is fundamental to software lifecycle governance in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Effective security governance requires clear assignment of roles and responsibilities, such as owners, controllers, and custodians, to ensure accountability for security-related tasks and data management within the organization. This establishes clear lines of responsibility and authority, which is fundamental to governance frameworks.

OCSP stands for Online Certificate Status Protocol. It is a protocol that allows applications to check the revocation status of a certificate in real-time. It works by sending a query to an OCSP responder, which is a server that maintains a database of revoked certificates. The OCSP responder returns a response that indicates whether the certificate is valid, revoked, or unknown. OCSP is faster and more efficient than downloading and parsing Certificate Revocation Lists (CRLs), which are large files that contain the serial numbers of all revoked certificates issued by a Certificate Authority (CA). References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 337 1

You want to place these technologies to reduce attack surface and enable secure protocols for the web architecture.

Suggested placements (following typical best practices for web architectures):

First node after Internet (Inbound Traffic Point):

FirewallControls and filters incoming traffic from the internet to block unwanted access.

Next node (Internal Traffic Control):

RouterRoutes packets inside the network and can apply some filtering.

Next layer (Between router and web infrastructure):

WAF (Web Application Firewall)Protects web servers from attacks like XSS, SQL injection, CSRF, directory traversal by inspecting HTTP/HTTPS traffic.

Web Servers:

Web serverHosts the application.

PKI Certificate:

Applied on the web server or WAF to enable HTTPS and secure protocols (TLS).

Part 2:

 Root cause analysis is a process of identifying and resolving the underlying factors that led to an incident. By conducting root cause analysis as part of incident response, security professionals can learn from the incident and implement corrective actions to prevent future incidents of the same nature. For example, if the root cause of a data breach was a weak password policy, the security team can enforce a stronger password policy and educate users on the importance of password security. Root cause analysis can also help to improve security processes, policies, and procedures, and to enhance security awareness and culture within the organization. Root cause analysis is not meant to gather loCs (indicators of compromise) for the investigation, as this is a task performed during the identification and analysis phases of incident response. Root cause analysis is also not meant to discover which systems have been affected or to eradicate any trace of malware on the network, as these are tasks performed during the containment and eradicationphases of incident response. References = CompTIA Security+ SY0-701 Certification Study Guide, page 424-425; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 5.1 - Incident Response, 9:55 - 11:18.

Comprehensive and Detailed Explanation From Exact Extract:

A playbook is a step-by-step, just-in-time reference used by Security Operations Center (SOC) analysts when responding to security alerts, incidents, and suspicious activities. Playbooks provide documented procedures for common scenarios such as malware detection, phishing investigations, ransomware response, and account compromise.

According to the CompTIA Security+ SY0-701 exam framework, playbooks support incident response by reducing analyst guesswork and ensuring consistency. They include details such as triage steps, required tools, escalation paths, log sources, and containment actions. This makes playbooks the most suitable document for immediate reference during live investigations.

Change management policies (A) govern system or configuration changes, not SOC operations. Risk profiles (B) provide organizational risk overviews, not incident-response steps. SIEM profiles (D) define correlation rules or dashboards but are not procedural guides.

Therefore, the correct answer is playbooks, which enable efficient, standardized, and repeatable responses to operational security events.

Dumpster diving is an attack method where attackers search through physical waste, such as discarded documents and printouts, to find sensitive information that has not been properly disposed of. In the context of printing centers, this could involve attackers retrieving printed documents containing confidential data that were improperly discarded without shredding or other secure disposal methods. This emphasizes the importance of proper disposal and physical security measures in cyber hygiene practices.

After completing a vulnerability assessment and remediating the identified vulnerabilities, the next step is to rescan the network to verify that the vulnerabilities have been successfully fixed and no new vulnerabilities have been introduced. A vulnerability assessment is a process of identifying and evaluating the weaknesses and exposures in a network, system, or application that could be exploited by attackers. A vulnerability assessment typically involves using automated tools, such as scanners, to scan the network and generate a report of the findings. The report may include information such as the severity, impact, and remediation of the vulnerabilities. The operations team is responsible for applying the appropriate patches, updates, or configurations to address the vulnerabilities and reduce the risk to the network. A rescan is necessary to confirm that the remediation actions have been effective and that the network is secure.

Conducting an audit, initiating a penetration test, or submitting a report are not the next steps after completing a vulnerability assessment and remediating the vulnerabilities. An audit is a process of reviewing and verifying the compliance of the network with the established policies, standards, and regulations. An audit may be performed by internal or external auditors, and it may use the results of the vulnerability assessment as part of the evidence. However, an audit is not a mandatory step after a vulnerability assessment, and it does not validate the effectiveness of the remediation actions.

A penetration test is a process of simulating a real-world attack on the network to test the security defenses and identify any gaps or weaknesses. A penetration test may use the results of the vulnerability assessment as a starting point, but it goes beyond scanning and involves exploiting the vulnerabilities to gain access or cause damage. A penetration test may be performed after a vulnerability assessment, but only with the proper authorization, scope, and rules of engagement. A penetration test is not a substitute for a rescan, as it does not verify that the vulnerabilities have been fixed.

Submitting a report is a step that is done after the vulnerability assessment, but before the remediation. The report is a document that summarizes the findings and recommendations of the vulnerability assessment, and it is used to communicate the results to the stakeholders and the operations team. The report may also include a follow-up plan and a timeline for the remediation actions. However, submitting a report is not the final step after the remediation, as it does not confirm that the network is secure.

Improving security awareness training directly addresses user behavior by teaching employees how to better recognize legitimate emails versus actual phishing attempts. Enhanced training can reduce the number of false positives by helping users more accurately identify true phishing attempts, lowering unnecessary reports and thus help desk workload.

FIM stands for File Integrity Monitoring, which is a method to secure data by detecting any changes or modifications to files, directories, or registry keys. FIM can help a security administrator track any unauthorized or malicious changes to the data, as well as verify the integrity and compliance of the data. FIM can also alert the administrator of any potential breaches or incidents involving the data.

Some of the benefits of FIM are:

It can prevent data tampering and corruption by verifying the checksums or hashes of the files.

It can identify the source and time of the changes by logging the user and system actions.

It can enforce security policies and standards by comparing the current state of the data with the baseline or expected state.

It can support forensic analysis and incident response by providing evidence and audit trails of the changes.

Using two different cloud solutions to store data is an example of platform diversity, which helps reduce dependency on a single cloud provider and enhances resilience against vendor-specific failures or outages.

Load balancing (A) distributes workloads across resources; parallel processing (B) refers to simultaneous processing of tasks; clustering (D) involves grouping servers to act as a single system.

Platform diversity is a recognized architectural strategy to improve availability and fault tolerance, covered in Security Architecture concepts for SY0-701【6:Chapter 10†CompTIA Security+ Study Guide】

SPF (Sender Policy Framework) DNS records specify which mail servers are authorized to send email on behalf of a domain. When new email servers are added but SPF records are not updated, recipient mail systems cannot verify the legitimacy of the new servers. As a result, those messages are flagged as spam or rejected altogether.

CompTIA Security+ SY0-701 highlights SPF as an essential email authentication mechanism used to reduce spoofing, phishing, and spam classification errors. Updating the SPF record to include the new servers ensures email reputation is maintained and messages are delivered properly.

CNAME (A) maps hostnames but does not affect outbound email legitimacy. SMTP (B) is the mail protocol, not the authentication method. DLP (C) governs sensitive data handling, not spam classification.

Thus, SPF is the correct answer.

Detailed Explanation:Data sovereignty refers to the principle that data stored in another country remains subject to the originating country’s laws. This is a common concern in cloud computing. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Data Sovereignty and Regulatory Compliance"​​.

ARP poisoning(also known as ARP spoofing) is a basicman-in-the-middle (MITM)attack that involves sending fake ARP responses to redirect traffic. This technique isnot sophisticatedand can be easily executed using freely available tools like Cain & Abel, Ettercap, or Wireshark.

Such attacks are often attempted byunskilled attackers (script kiddies)testing their abilities, especially in environments like schools. The term“unskilled attacker”fits best here, as credential stuffing and DMARC are unrelated to ARP poisoning.

Management review is a critical step in the change management process. Before implementing any design change, management reviews help evaluate the potential impact, security implications, and alignment with organizational goals and policies. This review ensures that the change is justified, risks are understood, and proper approvals are obtained.

Load testing is a performance test, maintenance notifications are communication steps, and procedure updates are documentation activities — all important but generally occur after management has approved the change.

The significance of management involvement in change governance is a foundational concept in the Security Program Management and Oversight domain of the SY0-701 exam【6:Chapter 16†CompTIA Security+ Study Guide】.

Data classification is a process of categorizing data based on its level of sensitivity, value, and impact to the organization if compromised. Data classification helps to determine the appropriate security controls and policies to protect the data from unauthorized access, disclosure, or modification. Different organizations may use different data classification schemes, but a common one is the four-tier model, which consists of the following categories: public, private, sensitive, and critical.

Public data is data that is intended for public access and disclosure, and has no impact to the organization if compromised. Examples of public data include marketing materials, press releases, and public web pages.

Private data is data that is intended for internal use only, and has a low to moderate impact to the organization if compromised. Examples of private data include employee records, financial reports, and internal policies.

Sensitive data is data that is intended for authorized use only, and has a high impact to the organization if compromised. Examples of sensitive data include personal information, health records, and intellectual property.

Critical data is data that is essential for the organization’s operations and survival, and has a severe impact to the organization if compromised. Examples of critical data include encryption keys, disaster recovery plans, and system backups.

Patient data is a type of sensitive data, as it contains personal and health information that is protected by law and ethical standards. Patient data should be used only by authorized personnel for legitimate purposes, and should be secured from unauthorized access, disclosure, or modification. Therefore, the systems administrator should use the sensitive data classification to secure patient data.

References = CompTIA Security+ SY0-701 Certification Study Guide, page 90-91; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 5.5 - Data Classifications, 0:00 - 4:30.

TheCommon Vulnerability Scoring System (CVSS)is astandardized framework for assessing the severity of vulnerabilities. It provides a numerical score (0-10) based on factors such asexploitability, impact, and complexity, helping security analystsprioritize remediation efforts based on risk.

Business impact analysis (A)helps identifycritical business functionsbut does not specificallyprioritize vulnerabilities.

Risk register (C)tracks identified risks but does not classify vulnerabilities.

Exposure factor (D)is used inquantitative risk assessmentbut is not an industry standard for vulnerability prioritization.

Confidentiality is the security concept that ensures data is protected from unauthorized access or disclosure. The principle of least privilege is a technique that grants users or systems the minimum level of access or permissions that they need to perform their tasks, and nothing more. By applying the principle of least privilege to a human resources fileshare, the permissions can be restricted to only those who have a legitimate need to access the sensitive data, such as HR staff, managers, or auditors. This can prevent unauthorized users, such as hackers, employees, or contractors, from accessing, copying, modifying, or deleting the data. Therefore, the principle of least privilege can enhance the confidentiality of the data on the fileshare. Integrity, availability, and non-repudiation are other security concepts, but they are not the best reason for permissions on a human resources fileshare to follow the principle of least privilege. Integrity is the security concept that ensures data is accurate and consistent, and protected from unauthorized modification or corruption. Availability is the security concept that ensures data is accessible and usable by authorized users or systems when needed. Non-repudiation is the security concept that ensures the authenticity and accountability of data and actions, and prevents the denial of involvement or responsibility. While these concepts are also important for data security, they are not directly related to the level of access or permissions granted to users or systems.

"Group Policy Objects (GPOs) are a feature of Microsoft Windows Active Directory that allow administrators to centrally manage and configure settings across multiple systems in an efficient manner. When a vulnerability such as SMBv1 (Server Message Block version 1) is identified onmultiple servers, GPOs can be used to disable this outdated and insecure protocol across all affected systems simultaneously. By creating a GPO to enforce a policy that disables SMBv1, the organization can ensure consistent remediation without manually configuring each server individually, making it the most efficient solution for domain-joined environments."

 Password spraying is a type of brute force attack that tries common passwords across several accounts to find a match. It is a mass trial-and-error approach that can bypass account lockout protocols. It can give hackers access to personal or business accounts and information. It is not a targeted attack, but a high-volume attack tactic that uses a dictionary or a list of popular or weak passwords12.

The logs show that the attacker is using the same password ("password123") to attempt to log in to different accounts ("admin", "user1", "user2", etc.) on the same web server. This is a typical pattern of password spraying, as the attacker is hoping that at least one of the accounts has a weak password that matches the one they are trying. The attacker is also using a tool called Hydra, which is one of the most popular brute force tools, often used in cracking passwords for network authentication3.

Account forgery is not the correct answer, because it involves creating fake accounts or credentials to impersonate legitimate users or entities. There is no evidence of account forgery in the logs, as the attacker is not creating any new accounts or using forged credentials.

Pass-the-hash is not the correct answer, because it involves stealing a hashed user credential and using it to create a new authenticated session on the same network. Pass-the-hash does not require the attacker to know or crack the password, as they use the stored version of the password to initiate a new session4. The logs show that the attacker is using plain text passwords, not hashes, to try to log in to the web server.

Brute-force is not the correct answer, because it is a broader term that encompasses different types of attacks that involve trying different variations of symbols or words until the correct password is found. Password spraying is a specific type of brute force attack that uses a single common password against multiple accounts5. The logs show that the attacker is using password spraying, not brute force in general, to try to gain access to the web server. References = 1: Password spraying: An overview of password spraying attacks … - Norton, 2: Security: Credential Stuffing vs. Password Spraying - Baeldung, 3: Brute ForceAttack: A definition + 6 types to know | Norton, 4: What is a Pass-the-Hash Attack? - CrowdStrike, 5: What is a Brute Force Attack? | Definition, Types & How It Works - Fortinet

Detailed Explanation:

Retention policies dictate how long data must be stored to comply with local and international regulations. Non-compliance can result in legal and financial penalties. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Retention and Legal Requirements"​​.

Aconflict of interest (B)arises when personal relationships or interests could potentially influence professional decisions. In this case, the CFO's friendship with the vendor could improperly affect the procurement decision-making process.

This scenario falls underDomain 5.3: Explain the importance of frameworks, policies, procedures, and controls—specifically under“Personnel policies (e.g., conflict of interest, mandatory vacations, job rotation).”

Before applying any updates or patches to a production VM, especially one with a 99% uptime SLA, it is crucial to first take a snapshot of the VM. This snapshot serves as a backup that can be quickly restored in case the update causes any issues, ensuring that the system can be returned to its previous state without violating the SLA. This step mitigates risk and is a standard best practice in change management for critical systems.

References = CompTIA Security+ SY0-701 study materials, focusing on change management and backup strategies​​.

An SLA (Service-Level Agreement) defines the expected performance, availability, uptime, response times, and responsibilities between a provider and a client. The requirement in the scenario—“97% uptime”—is a classic example of an SLA metric. Security+ SY0-701 emphasizes that SLAs outline measurable service expectations so the client can assess compliance and performance.

A BPA (A) outlines business partnership terms, not performance uptime. An MOU (B) documents mutual understanding but is not legally binding and does not include uptime metrics. An NDA (C) protects confidentiality, not availability or service guarantees.

Thus, the correct answer is D: SLA.

Ransomware-as-a-service is a type of cybercrime where hackers sell or rent ransomware tools or services to other criminals who use them to launch attacks and extort money from victims. This is a typical example of organized crime, which is a group of criminals who work together to conduct illegal activities for profit. Organized crime is different from other types of threat actors, such as insider threats, hacktivists, or nation-states, who may have different motives, methods, or targets. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 17 1

Installing a host-based content filtering solution on the endpoints ensures that web traffic is filtered locally even when the VPN connection to the on-premises proxy fails, maintaining protection for remote users.

Network access control (A) manages device network access, local gateway configuration (B) does not solve protection if VPN fails, and public NAT (C) exposes internal resources and increases risk.

Endpoint filtering complements VPN for resilient web security, covered in Security Architecture and Operations【6:Chapter 11†CompTIA Security+ Study Guide】.

Detailed Explanation:Access control lists (ACLs) allow administrators to fine-tune file permissions by specifying which users or groups have access to a file and defining the level of access. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Access Control Mechanisms"​​.

The scenario describes a situation where a user unknowingly triggers an unwanted action, such as changing their password, by clicking a malicious link. This is indicative of a Cross-Site Request Forgery (CSRF) attack, where an attacker tricks the user into executing actions they did not intend to perform on a web application in which they are authenticated.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of web application security and common attack vectors like CSRF​​.

Software-defined networking (SDN) enables microsegmentation by allowing administrators to create fine-grained, dynamic network segments at the software layer independent of physical network topology. This capability isolates workloads and controls traffic flows between segments, enhancing security within data centers and cloud environments.

Next-generation firewalls (A) provide advanced filtering and inspection but do not inherently deliver the granular segmentation flexibility of SDN. Embedded systems (C) and air-gapped systems (D) refer to specific hardware or physical isolation techniques but do not implement microsegmentation as a network control method.

The concept of microsegmentation through SDN is detailed in the Security Architecture domain of the SY0-701 exam【6:Chapter 3†CompTIA Security+ Study Guide】.

Aprocedureprovides step-by-step instructions on how to complete a specific security task, ensuring consistency and accuracy. Unlike policies, which define high-level security expectations,procedures are detailed and operational. For example, apassword reset procedurewould outline the exact steps IT support must follow when assisting users.

Policy: Defines security objectives and rules (e.g., "All passwords must be complex").

Standard: Specifies required technologies or configurations.

Guideline: Provides recommendations but is not mandatory.

Procedure: Gives exact instructions to perform tasks.

The company should request a certification from the vendor that confirms the storage array has been disposed of securely and in compliance with the company’s policies and standards. A certification provides evidence that the vendor has followed the proper procedures and methods to destroy the classified data and prevent unauthorized access or recovery. A certification may also include details such as the date, time, location, and method of disposal, as well as the names and signatures of the personnel involved. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3, page 1441

A tabletop exercise is a simulation-based activity where incident response team members and relevant stakeholders walk through a hypothetical security incident in a discussion-based format. This exercise helps validate response plans, roles, and communication channels without actual system disruption.

Lessons learned (A) is a post-incident review, digital forensics (B) is evidence collection after an incident, and root cause analysis (D) investigates the underlying cause after an event.

Tabletop exercises are standard practices within the Security Operations domain to prepare teams for real incidents【6:Chapter 14†CompTIA Security+ Study Guide】.

Monitoring outbound traffic is essential for detecting unauthorized data exfiltration from a system. A new vulnerability that allows malware to move data unauthorizedly would typically attempt to send this data out of the network. By monitoring outbound traffic, security tools can detect unusual data transfers, trigger alerts, and help prevent the exfiltration of sensitive information.

Poor input validation in databases typically leads to SQL Injection (SQLi) vulnerabilities, where attackers manipulate input fields to execute arbitrary SQL commands and gain unauthorized data access or control.

XSS (A) affects web applications' output rendering, command injection (B) affects OS commands, and buffer overflow (C) affects memory management, so they don't directly relate to database input validation.

SQLi is a critical vulnerability extensively covered in the Application Security domain【6:Chapter 6†CompTIA Security+ Study Guide】.

When the government bans a vendor, the legal concern is sanctions—laws that restrict purchasing, using, or importing products from certain companies or countries. The general counsel’s job is to ensure the organization is not violating federal restrictions, export controls, trade compliance laws, or sanctions lists such as OFAC or government procurement bans.

Security+ SY0-701 notes that legal and regulatory compliance is a critical part of risk management, especially when handling prohibited vendors or technologies. Continued use of banned devices could expose the organization to legal penalties, fines, or federal investigation.

Data sovereignty (B) refers to data storage location laws, not hardware bans. Cost of replacement (C) is an operational concern, not a legal one. Loss of license (D) typically applies to software, not network hardware.

Therefore, the general counsel’s primary concern is A: Sanctions.

CVSS (Common Vulnerability Scoring System) provides a standardized way to rate the severity of software vulnerabilities. Organizations use CVSS scores to prioritize which vulnerabilities to address first, focusing on those with the highest risk.

Encrypting hard drives is a direct implementation of confidentiality, one of the three pillars of the CIA Triad emphasized in CompTIA Security+ SY0-701. Full disk encryption ensures that if a laptop, workstation, or server drive is stolen or accessed without authorization, the data remains unreadable without the decryption key.

This controls unauthorized disclosure and protects sensitive business, financial, and personal information. Drive encryption is widely required for compliance frameworks such as HIPAA, PCI-DSS, and GDPR.

Integrity (A) refers to preventing unauthorized modification of data, which encryption alone does not guarantee. Authentication (B) confirms user identity, such as passwords or biometrics, but is unrelated to data-at-rest protection. Zero Trust (C) is an architectural model requiring constant verification; it is not a control for hard drive encryption.

Since the sole purpose of encrypting storage is to ensure data confidentiality, the correct answer is D.

Full disk encryption (FDE) is a technique that encrypts all the data on a hard drive, including the operating system, applications, and files. FDE protects the data from unauthorized access in case the laptop is lost, stolen, or disposed of without proper sanitization. FDE requires the user to enter a password, a PIN, a smart card, or a biometric factor to unlock the drive and boot the system. FDE can be implemented by using software solutions, such as BitLocker, FileVault, or VeraCrypt, or by using hardware solutions, such as self-encrypting drives (SEDs) or TrustedPlatform Modules (TPMs). FDE is a recommended encryption technique for laptops and other mobile devices that store sensitive data.

Partition encryption is a technique that encrypts only a specific partition or volume on a hard drive, leaving the rest of the drive unencrypted. Partition encryption is less secure than FDE, as it does not protect the entire drive and may leave traces of data on unencrypted areas. Partition encryption is also less convenient than FDE, as it requires the user to mount and unmount the encrypted partition manually.

Asymmetric encryption is a technique that uses a pair of keys, one public and one private, to encrypt and decrypt data. Asymmetric encryption is mainly used for securing communication, such as email, web, or VPN, rather than for encrypting data at rest. Asymmetric encryption is also slower and more computationally intensive than symmetric encryption, which is the type of encryption used by FDE and partition encryption.

Database encryption is a technique that encrypts data stored in a database, such as tables, columns, rows, or cells. Database encryption can be done at the application level, the database level, or the file system level. Database encryption is useful for protecting data from unauthorized access by database administrators, hackers, or malware, but it does not protect the data from physical theft or loss of the device that hosts the database.

To ensure that sensitive data, such as Personally Identifiable Information (PII), is not modified, the bank should implement file integrity monitoring (FIM). FIM tracks changes to files and provides alerts if unauthorized modifications are detected, ensuring data integrity.

Full disk encryption protects data at rest but does not prevent or monitor modifications.

Network access control (NAC) manages access to the network but doesn't monitor file changes.

User behavior analytics (UBA) detects suspicious user activities but is not focused on file integrity​​​.

Detailed Explanation:Mean Time to Repair (MTTR) is a key metric in risk management, reflecting the time required to repair a failed component, such as a generator, and restore operations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Business Continuity Metrics"​​.

CVSS (Common Vulnerability Scoring System) is used to assign severity scores to security vulnerabilities, allowing organizations to assess risk and prioritize remediation efforts. By using CVSS scores, teams can address the most critical vulnerabilities first, based on the potential impact.

Attestation refers to providing formal evidence or proof that a particular process or activity has been completed according to standards or requirements. In this context, attestation involves demonstrating to customers or stakeholders that software developers have received appropriate training on secure coding practices.

Assurance generally refers to confidence or guarantees about the security posture but does not specifically mean proving or certifying training. Due diligence is the effort made to ensure compliance or safety, but it is not the act of proving training has occurred. A contract is a legal agreement, which may include requirements for training but is not the act of proving training itself.

The importance of attestation in compliance and governance processes is discussed in the Security Program Management and Oversight domain in SY0-701 materials【7:Chapter 5†CompTIA Security+ Practice Tests】.

Exercising the right to be forgotten involves formally requesting the social media provider to delete all personal data associated with the account, ensuring removal from their servers and backups in accordance with privacy regulations.

Scheduled downtime is a planned period of time when a system or service is unavailable for maintenance, updates, upgrades, or other changes. Scheduled downtime gives administrators a set period to perform changes to an operational system without disrupting the normal business operations or affecting the availability of the system or service. Scheduled downtime also allows administrators to inform the users and stakeholders about the expected duration and impact of the changes. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 12: Security Operations and Administration, page 579 1

An Access Control List (ACL) is a technical mechanism used to explicitly define permissions for files, folders, or other resources. ACLs specify which users or system processes are granted access to objects and what operations are allowed on given objects. This allows the administrator to centrally and granularly manage file permissions for a group or team.

Detailed Explanation:Standard operating procedures (SOPs) outline the steps to be followed to maintain a secure baseline, such as testing and deploying patches while minimizing risk to the system. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Patch Management and Baseline Compliance"​​.

 Automation is the best way to consistently determine on a daily basis whether security settings on servers have been modified. Automation is the process of using software, hardware, or other tools to perform tasks that would otherwise require human intervention or manual effort. Automation can help to improve the efficiency, accuracy, and consistency of security operations, as well as reduce human errors and costs. Automation can be used to monitor, audit, and enforce security settings on servers, such as firewall rules, encryption keys, access controls, patch levels, and configuration files. Automation can also alert security personnel of any changes or anomalies that may indicate a security breach or compromise12.

The other options are not the best ways to consistently determine on a daily basis whether security settings on servers have been modified:

Compliance checklist: This is a document that lists the security requirements, standards, or best practices that an organization must follow or adhere to. A compliance checklist can help to ensure that the security settings on servers are aligned with the organizational policies and regulations, but it does not automatically detect or report any changes or modifications that may occur on a daily basis3.

Attestation: This is a process of verifying or confirming the validity or accuracy of a statement, claim, or fact. Attestation can be used to provide assurance or evidence that the security settings on servers are correct and authorized, but it does not continuously monitor or audit any changes or modifications that may occur on a daily basis4.

Manual audit: This is a process of examining or reviewing the security settings on servers by human inspectors or auditors. A manual audit can help to identify and correct any security issues or discrepancies on servers, but it is time-consuming, labor-intensive, and prone to human errors. A manual audit may not be feasible or practical to perform on a daily basis.

Mobile Device Management (MDM) allows administrators to configure, update, monitor, and push applications or features to company-provided mobile devices remotely and quickly. The requirement to restore missing features within 48 hours means IT needs centralized control and fast deployment—capabilities MDM provides.

With MDM, IT can:

Push required apps

Reconfigure devices

Enforce security policies

Restore missing features

Update OS and settings remotely

COPE (B) relates to ownership and usage policy, not configuration management. EDR (A) protects against malware but cannot restore missing productivity features. FDE (D) encrypts storage and is unrelated to application availability.

MDM is the only option allowing rapid, centralized remediation.

Thus, C is correct.

Tokenization is the most effective method for protecting sensitive data at rest within a database. Tokenization replaces sensitive information—such as credit card numbers, SSNs, or personal identifiers—with meaningless surrogate values (tokens). The actual data is stored securely in a separate token vault, reducing exposure if the primary database is compromised.

Hashing (A) is one-way and protects integrity, not usability, making it inappropriate for data that must later be retrieved. Masking (B) hides data from users but does not secure stored data in the database. Obfuscation (D) makes data harder to understand but is reversible and not intended for strong security.

Security+ SY0-701 identifies tokenization as a key control for data-at-rest protection, especially in regulated industries like finance and healthcare. It prevents attackers from accessing real data even if the database is breached, significantly reducing risk and compliance impact. This aligns with the exam’s emphasis on confidentiality and data protection strategies in stored environments.

Detailed Explanation:Rules of engagement specify the agreed-upon boundaries, scope, and procedures for a penetration test to ensure compliance and avoid disruption to the environment. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Penetration Testing Procedures"​​.

Geographic dispersion is the practice of having backup data stored in different locations that are far enough apart to minimize the risk of a single natural disaster affecting both sites. This ensures that the company can recover its regulated data in case of a disaster at the primary site. Platform diversity, hot site, and load balancing are not directly related to the protection of backup data from natural disasters. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 449; Disaster Recovery Planning: Geographic Diversity

 A bastion host is a special-purpose server that is designed to withstand attacks and provide secure access to internal resources. A bastion host is usually placed on the edge of a network, acting as a gateway or proxy to the internal network. A bastion host can be configured to allowonly certain types of traffic, such as SSH or HTTP, and block all other traffic. A bastion host can also run security software such as firewalls, intrusion detection systems, and antivirus programs to monitor and filter incoming and outgoing traffic. A bastion host can provide administrative access to internal resources by requiring strong authentication and encryption, and by logging all activities for auditing purposes12.

A bastion host is the most secure method among the given options because it minimizes the traffic allowed through the security boundary and provides a single point of control and defense. A bastion host can also isolate the internal network from direct exposure to the internet or other untrusted networks, reducing the attack surface and the risk of compromise3.

Deploying a perimeter network is not the correct answer, because a perimeter network is a network segment that separates the internal network from the external network. A perimeter network usually hosts public-facing services such as web servers, email servers, or DNS servers that need to be accessible from the internet. A perimeter network does not provide administrative access to internal resources, but rather protects them from unauthorized access. A perimeter network can also increase the complexity and cost of network management and security4.

Installing a WAF is not the correct answer, because a WAF is a security tool that protects web applications from common web-based attacks by monitoring, filtering, and blocking HTTP traffic. A WAF can prevent attacks such as cross-site scripting, SQL injection, or file inclusion, among others. A WAF does not provide administrative access to internal resources, but rather protects them from web application vulnerabilities. A WAF is also not a comprehensive solution for network security, as it only operates at the application layer and does not protect against other types of attacks or threats5.

Utilizing single sign-on is not the correct answer, because single sign-on is a method of authentication that allows users to access multiple sites, services, or applications with one username and password. Single sign-on can simplify the sign-in process for users and reduce the number of passwords they have to remember and manage. Single sign-on does not provide administrative access to internal resources, but rather enables access to various resources that the user is authorized to use. Single sign-on can also introduce security risks if the user’s credentials are compromised or if the single sign-on provider is breached6. References = 1: Bastion host - Wikipedia, 2: 14 Best Practices to Secure SSH Bastion Host - goteleport.com, 3: The Importance Of Bastion Hosts In Network Security, 4: What is the network perimeter? | Cloudflare, 5: What is a WAF? | Web Application Firewall explained, 6: [What is single sign-on (SSO)? - Definition from WhatIs.com]

 Sanitization is the process of removing sensitive data from a storage device or a system before it is disposed of or reused. Sanitization can be done by using software tools or hardware devices that overwrite the data with random patterns or zeros, making it unrecoverable. Sanitization is different from destruction, which is the physical damage of the storage device to render it unusable. Sanitization is also different from enumeration, which is the identification of network resources or devices, and inventory, which is the tracking of assets and their locations. The policy of securely wiping hard drives before sending decommissioned systems to recycling is an example of sanitization, as it ensures that no confidential data can be retrieved from the recycled devices. References = Secure Data Destruction – SY0-601 CompTIA Security+ : 2.7, video at 1:00; CompTIA Security+ SY0-701 Certification Study Guide, page 387.

Applying the latest OS updates, patches, and endpoint definitions is the most effective way to prevent known exploits, which are attacks leveraging previously discovered vulnerabilities for which fixes are available.

Comprehensive and Detailed In-Depth Explanation:

AnEndpoint Detection and Response (EDR)solution is designed tomonitor, detect, and respond to security incidents on endpoints (such as workstations and servers). Itcollects and analyzes data, detecting suspicious activity and forwarding relevant information for further investigation.

Network Access Control (NAC) (A)enforces network access policies but does not analyze security threats on hosts.

Intrusion Prevention Systems (IPS) (B)detect and block network threats but do not provide deep endpoint analytics.

Security Information and Event Management (SIEM) (C)aggregates logs and provides security analytics but lacks direct endpoint detection and response capabilities.

EDR is the best choicefor analyzing and responding to endpoint security incidents.

Impossible travel (A)refers to logins fromgeographically distant locations within a time period that makes travel between them physically impossible. In this case, a user logging in fromChicago and Rome within a short timeframetriggers this anomaly.

This is a strong indicator of acompromised accountorstolen credentialsbeing used elsewhere.

Risk appetite refers to the level of risk that an organization is willing to accept in order to achieve its objectives. In this scenario, the security engineer is concerned that the timeframe for implementing a new application does not allow for sufficient cybersecurity due diligence. This reflects a situation where the organization’s risk appetite might be too high if it proceeds without the necessary security checks.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of risk management and understanding organizational risk appetite​​.

When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL). This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.

End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.

End of business and End of testing do not apply in this context​​.

Detailed Explanation:The correct sequence is to first establish secure baselines by determining the required configurations, deploy those configurations across systems, and finally maintain the configurations through regular updates and auditing. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Secure Baseline Development"​​.

Tuning is the activity of adjusting the configuration or parameters of a security tool or system to optimize its performance and reduce false positives or false negatives. Tuning can help to filter out the normal or benign activity that is detected by the security tool or system, and focus on the malicious or anomalous activity that requires further investigation or response. Tuning can also help to improve the efficiency and effectiveness of the security operations center by reducing the workload and alert fatigue of the analysts. Tuning is different from aggregating, which is the activity of collecting and combining data from multiple sources or sensors to provide a comprehensive view of the security posture. Tuning is also different from quarantining, which is the activity of isolating a potentially infected or compromised device or system from the rest of the network to prevent further damage or spread. Tuning is also different from archiving, which is the activity of storing and preserving historical data or records for future reference or compliance. The act of ignoring detected activity in the future that is deemed normal by the security operations center is an example of tuning, as it involves modifying the settings or rules of the security tool or system to exclude the activity from the detection scope. Therefore, this is the best answer among the given options. References = Security Alerting and Monitoring Concepts and Tools – CompTIA Security+ SY0-701: 4.3, video at 7:00; CompTIA Security+ SY0-701 Certification Study Guide, page 191.

Containmentis the phase wherean organization attempts to minimize the damage caused by a security incident. This may involve isolating affected systems, blocking malicious traffic, or temporarily shutting down compromised services to prevent further impact.

Recovery (A)focuses on restoring normal operations after an incident.

Preparation (C)involves planning and readiness before an incident occurs.

Analysis (D)involvesinvestigating the root causeand assessing the damage.

A regulatory requirement is a mandate imposed by a government or an authority that must be followed by an organization or an individual. In a banking environment, audits are often required by regulators to ensure compliance with laws, standards, and policies related to security, privacy, and financial reporting. Audits help to identify and correct any gaps or weaknesses in the security posture and the internal controls of the organization.

To ensure that all systems requiring the patch are updated, the systems administrator must maintain an accurate asset inventory. This inventory lists all hardware and software assets within the organization, allowing the administrator to identify which systems are affected by the patch and ensuring that none are missed during the update process.

Network enumeration is used to discover devices on a network but doesn't track software that requires patching.

Data certification and procurement process are unrelated to tracking systems for patching purposes​​.

Implementing playbooks as part of a SOAR (Security Orchestration, Automation, and Response) platform enables the automation of routine security tasks and the standardized response to common alerts. Playbooks help filter and validate alerts, reducing the number of false positives that analysts need to manually investigate. SOAR tools are specifically designed to improve efficiency, consistency, and accuracy in incident response, allowing analysts to focus on genuine threats rather than being overwhelmed by noise.

Secure Shell (SSH) is a protocol used for secure command-line access to remote systems, while Secure File Transfer Protocol (SFTP) is an extension of SSH used specifically for securely transferring files. Both SSH and SFTP ensure that data is encrypted during transmission, protecting it from interception or tampering.

Bug bounty programs invite vetted external researchers to report software vulnerabilities in exchange for rewards. According to Security+ SY0-701, two major benefits are:

(1) Reduction in the number of zero-day vulnerabilities (B) – Ethical hackers can discover unknown vulnerabilities before malicious attackers do. These vulnerabilities are often zero-days because they are unknown to vendors at the time of discovery. Bug bounty programs surface these issues early, helping organizations mitigate severe risks proactively.

(2) Quicker discovery of vulnerabilities (E) – A distributed network of global security researchers can identify vulnerabilities far faster than an internal team alone. This accelerates detection, increases coverage, and lowers attacker dwell time.

Option A (Transference of risk) is incorrect because bug bounties do not transfer risk—they help identify vulnerabilities. C (Security awareness) relates to internal training, not bug bounties. D (Reduced cost) is misleading; bug bounties can be expensive depending on payout structure. F (Patch management) does not directly improve through bug bounty programs.

Therefore, the correct benefits are B and E.

A responsibility matrix, often referred to in cloud computing as the Shared Responsibility Model, defines the exact roles, duties, and expectations between a cloud service provider (CSP) and the customer. This includes who is responsible for configuration, maintenance, patching, logging, updates, identity management, network security, and data protection.

According to the SY0-701 exam objectives, cloud models such as SaaS, PaaS, and IaaS all divide responsibilities differently. The responsibility matrix clarifies these boundaries so that neither party assumes the other is handling a critical security task. Misunderstandings in these areas can create dangerous security gaps, such as unpatched virtual machines, misconfigured storage buckets, or weak access controls.

A Service-Level Agreement (A) focuses on uptime, performance, and service expectations—not shared security roles. A Memorandum of Understanding (C) describes high-level cooperation between organizations, while an NDA (D) protects confidential information.

The responsibility matrix is emphasized under Security Program Management, specifically in managing third-party relationships and cloud provider governance, ensuring both parties understand their obligations and reducing the risk of misconfigurations or operational vulnerabilities.

Detailed Explanation:Privileged Access Management (PAM) solutions enhance security by enforcing strong authentication, rotation of credentials, and access control for shared accounts. This is especially critical in scenarios like SSO failures. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Privileged Access and Identity Management"​​.

The Common Vulnerability Scoring System (CVSS) is a standardized framework for assessing the severity of security vulnerabilities. It helps organizations prioritize vulnerability patching by providing a numerical score that reflects the potential impact and exploitability of a vulnerability. CVSS scores are used to gauge the urgency of patching vulnerabilities within a company’s IT environment.

Data classification is the process of assigning labels to data based on its sensitivity and business impact. Different organizations and sectors may have different data classification schemes, but a common one is the following1:

Public: Data that can be freely disclosed to anyone without any harm or risk.

Private: Data that is intended for internal use only and may cause some harm or risk if disclosed.

Confidential: Data that is intended for authorized use only and may cause significant harm or risk if disclosed.

Restricted: Data that is intended for very limited use only and may cause severe harm or risk if disclosed.

In this scenario, the company is developing a critical system for the government and storing project information on a fileshare. This data is likely to be classified as confidential and restricted, because it is not meant for public or private use, and it may cause serious damage to national security or public safety if disclosed. The government may also have specific requirements or regulations for handling such data, such as encryption, access control, and auditing2. References: 1: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 16-17 2: Data Classification Practices: Final Project Description Released

Data masking replaces sensitive data with realistic but fictional data, preserving format and usability while protecting confidential information during testing in environments like UAT (User Acceptance Testing).

Tokenization (B) replaces data with tokens but is more common for payment data in production. Obfuscation (C) scrambles data but is less structured than masking. Encryption (D) protects data confidentiality but may not be practical for testing.

Data masking is a best practice for protecting sensitive data in non-production environments covered in the General Security Concepts domain【6:Chapter 7†CompTIA Security+ Study Guide】.

Comprehensive and Detailed Explanation From Exact Extract:

VM escape occurs when an attacker inside a virtual machine breaks out of the guest OS and gains access to the underlying host hypervisor or other virtual machines. In this scenario, the penetration tester executes a script to inject a malicious payload that allows access to the host filesystem—this is the textbook definition of VM escape.

The SY0-701 exam specifically identifies VM escape as one of the most critical virtualization vulnerabilities, as it defeats isolation and can compromise entire virtual environments. This typically results from flaws in hypervisor software, improper sandboxing, or insecure VM tools.

Cross-site scripting (B) affects web applications and browsers, not hypervisors. Malicious updates (C) involve tampered patch delivery. SQL injection (D) targets databases through application input fields.

Because the attacker moved from a VM to the host system, the correct classification is VM escape, a high-severity virtualization vulnerability.

An application allow list is a security technique that specifies which applications are authorized to run on a system and blocks all other applications. An application allow list can best protect against an employee inadvertently installing malware on a company system because it prevents the execution of any unauthorized or malicious software, such as viruses, worms, trojans, ransomware, or spyware. An application allow list can also reduce the attack surface and improve the performance of the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 11: Secure Application Development, page 551 1

Restricting access to a router's web management interface is apreventive control (C). This type of control is implementedbefore a threat occursto reduce the likelihood of exploitation.

To mitigate the risk of sensitive data being exfiltrated from the environment, the IT manager should implement a Data Loss Prevention (DLP) solution. DLP monitors and controls the movement of sensitive data, ensuring that unauthorized transfers are blocked and potential data breaches are prevented.

XDR (Extended Detection and Response) is useful for threat detection across multiple environments but doesn't specifically address data exfiltration.

SPF (Sender Policy Framework) helps prevent email spoofing, not data exfiltration.

DMARC (Domain-based Message Authentication, Reporting & Conformance) also addresses email security and spoofing, not data exfiltration​​.

Purple is the team that combines both offensive and defensive testing techniques to protect an organization’s critical systems. Purple is not a separate team, but rather a collaboration between the red team and the blue team. The red team is the offensive team that simulates attacks and exploits vulnerabilities in the organization’s systems. The blue team is the defensive team that monitors and protects the organization’s systems from real and simulated threats. The purple team exists to ensure and maximize the effectiveness of the red and blue teams by integrating the defensive tactics and controls from the blue team with the threats and vulnerabilities found by the red team into a single narrative that improves the overall security posture of the organization. Red, blue, and yellow are other types of teams involved in security testing, but they do not combine both offensive and defensive techniques. The yellow team is the team that builds software solutions, scripts, and other programs that the blue team uses in the security testing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1331; Penetration Testing: Understanding Red, Blue, & Purple Teams3

A bug bounty is a program that rewards security researchers for finding and reporting vulnerabilities in an application or system. Bug bounties are often used by companies to improve their security posture and incentivize ethical hacking. A bug bounty program typically defines the scope, rules, and compensation for the researchers. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 10.

Detailed Explanation:Privileged access management (PAM) solutions effectively mitigate pass-the-hash attacks by enforcing least privilege and session management for administrative accounts. These tools restrict how and when credentials can be accessed, thereby reducing attack surfaces.

802.1X is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. It supports the use of certificates for authentication, can quarantine unapproved devices, and ensures that only approved and updated devices can access network resources. This protocol best meets the requirements of securing both wired and wireless networks with internal certificates.

Step 1: Analyze the Data and Question

Scenario:

Company data (directory, compensation report, user data) is found on the dark web.

CIO asks you to investigate and implement the most secure protection for employee accounts.

Task:

Identify weak password practices.

Choose the best containment step that keeps evidence on the host uncompromised.

Step 2: Identify Weak Password Practices

Prompt: Select all weak password practices from the list:

Age

Reuse

Length

Expiration

Complexity

Let’s analyze each:

Age: If passwords are used for a long time without change, it's a weak practice (passwords become easier to compromise over time).

Reuse: Reusing passwords across accounts is a serious weak practice (if one gets leaked, all accounts are at risk).

Length: Short passwords are weak; password length matters. If passwords are too short, that’s a weak practice.

Expiration: Forcing frequent expiration can lead to weaker passwords (users pick simple ones), but not expiring passwords at all is also risky. (For most exams, "expiration" by itself isn't usually called a weak practice unless the policy is poorly set.)

Complexity: Lack of complexity (not requiring numbers, symbols, etc.) is a weak practice.

So, select all that are truly weak practices:

Answer for weak password practices (check all that apply):

✔️ Age

✔️ Reuse

✔️ Length

✔️ Complexity

(Expiration is more controversial; on the exam, the main focus is usually on Age, Reuse, Length, and Complexity.)

Step 3: Choose the Best Containment Step

Prompt:

Select the containment step that will leave potential evidence on the host uncompromised:

PIN code

FIDO security key

SMS authentication

OTP token

Containment step means “what security solution can you implement to protect employee accounts going forward, while preserving digital evidence on potentially compromised systems?”

The most secure solution for account protection among these, that also doesn’t interfere with host evidence, is FIDO security key.

Why?

PIN code: Not strong enough; also may be stored locally.

SMS authentication: Can be intercepted; often leaves traces on the host (like SMS logs).

OTP token: Similar risks, some implementations might log to the host.

FIDO security key: Hardware-based, phishing-resistant, no codes sent to the host, and doesn’t alter host evidence—authentication happens off the device.

So, the best answer is:

FIDO security key

Step 4: Solution Recap and Justification

Detailed Solution Recap:

Identify weak password practices:

Weaknesses: passwords are reused, not long enough, lack complexity, and used for a long time.

Select the best security solution:

Implement FIDO security keys for employees.

Most secure among listed options.

Hardware-based; resistant to phishing, interception, and does not leave evidence on the compromised host (which is important for forensics).

Infrastructure as Code (IaC)enables automated provisioning and configuration of infrastructure, making environmentsrepeatable, consistent, and scalable. The ability tobetter manage and replicate configurations (B)ensures that security settings are not missed and reduces misconfigurations.

According to theCompTIA Security+ SY0-701exam objectives underDomain 4.1 (Explain the security implications of different architecture models),IaCprovides the ability to"automatically enforce security controls"and manageconsistent configuration states, reducing human error.

Preparation is the phase in the incident response process when a security analyst reviews roles and responsibilities, as well as the policies and procedures for handling incidents. Preparation also involves gathering and maintaining the necessary tools, resources, and contacts for responding to incidents. Preparation can help a security analyst to be ready and proactive when an incident occurs, as well as to reduce the impact and duration of the incident.

Some of the activities that a security analyst performs during the preparation phase are:

Defining the roles and responsibilities of the incident response team members, such as the incident manager, the incident coordinator, the technical lead, the communications lead, and the legal advisor.

Establishing the incident response plan, which outlines the objectives, scope, authority, and procedures for responding to incidents, as well as the escalation and reporting mechanisms.

Developing the incident response policy, which defines the types and categories of incidents, the severity levels, the notification and reporting requirements, and the roles and responsibilities of the stakeholders.

Creating the incident response playbook, which provides the step-by-step guidance and checklists for handling specific types of incidents, such as denial-of-service, ransomware, phishing, or data breach.

Acquiring and testing the incident response tools, such as network and host-based scanners, malware analysis tools, forensic tools, backup and recovery tools, and communication and collaboration tools.

Identifying and securing the incident response resources, such as the incident response team, the incident response location, the evidence storage, and the external support.

Building and maintaining the incident response contacts, such as the internal and external stakeholders, the law enforcement agencies, the regulatory bodies, and the media.

The scenario described, where client files are only accessible to employees who "need to know" the information, reflects the concept of confidentiality. Confidentiality ensures that sensitive information is only accessible to those who are authorized to view it, preventing unauthorized access.

Availability ensures that data is accessible when needed but doesn’t focus on restricting access.

Integrity ensures that data remains accurate and unaltered but doesn’t pertain to access control.

Non-repudiation ensures that actions cannot be denied after they are performed, but this concept is unrelated to access control​​.

A service level agreement (SLA) is a type of agreement that defines the expectations and responsibilities between a service provider and a customer. It usually includes the quality, availability, and performance metrics of the service, as well as the time frame in which the provider needs to respond to service requests, incidents, or complaints. An SLA can help ensure that the customer receives the desired level of service and that the provider is accountable for meeting the agreed-upon standards.

The scenario indicates that a user downloaded an unofficial patch, applied it, and afterward system files changed—detected by FIM. This strongly suggests the presence of a rootkit, which is designed to deeply embed itself into the operating system, altering core system files, modifying kernels, and hiding its presence.

Rootkits commonly replace or modify OS-level files, which results in changed file hashes—exactly what FIM is detecting. Rootkits often gain privileged, persistent control and are frequently disguised as legitimate updates or patches.

A logic bomb (A) is triggered by an event but does not typically modify OS files. A keylogger (B) captures keystrokes but doesn’t modify system files broadly. Ransomware (C) encrypts files, not silently alters system components.

Thus, the best match is D: Rootkit.

An engineer should recommend the decommissioning of a network device when the device poses a security risk or a compliance violation to the enterprise environment. A device that cannot meet the encryption standards or receive authorized updates is vulnerable to attacks and breaches, and may expose sensitive data or compromise network integrity. Therefore, such a device should be removed from the network and replaced with a more secure and updated one.

AES-256 is a symmetric encryption algorithm widely used to protect data at rest by converting plaintext into ciphertext that is unreadable without the proper key. It provides strong confidentiality and is a standard for encrypting stored data.

TLS 1.2 (A) secures data in transit, not at rest. Masking (C) obscures data but typically for display or limited use and is reversible. Salting (D) is used alongside hashing to protect passwords and data integrity but does not encrypt data.

Encryption with AES-256 is recognized as a best practice for securing stored data in the Security+ Cryptography and General Security Concepts domains【6:Chapter 7†CompTIA Security+ Study Guide】.

A Host-based Intrusion Prevention System (HIPS) protects individual devices by monitoring and preventing malicious activity directly on the host. It is ideal for protecting traveling employees’ devices outside the corporate network.

Isolation (A) and segmentation (B) apply to networks, and ACL (Access Control List) (C) restricts network traffic but does not provide host-level protection.

HIPS is emphasized in Security Operations for endpoint protection【6:Chapter 11†CompTIA Security+ Study Guide】.

Side loading is the process of installing applications from unofficial sources, often bypassing standard app stores. This increases the risk of installing malicious software, such as a rootkit, which is a type of malware designed to provide persistent privileged access while hiding its presence.

Air-gapping is the most effective way to protect an application server running unsupported software from network threats. By physically isolating the server from any network connection (no wired or wireless communication), it is protected from external cyber threats. While other options like port security or a screened subnet can provide some level of protection, an air gap offers the highest level of security by preventing any network-based attacks entirely.

A buffer overflow is a type of software vulnerability that occurs when an application writes more data to a memory buffer than it can hold, causing the excess data to overwrite adjacent memory locations. This can lead to unexpected behavior, such as crashes, errors, or code execution. A buffer overflow can be exploited by an attacker to inject malicious code or commands into the application, which can compromise the security and functionality of the system. An organization’s internet-facing website was compromised when an attacker exploited a buffer overflow. To best protect against similar attacks in the future, the organization should deploy a web application firewall (WAF). A WAF is a type of firewall that monitors and filters the traffic between a web application and the internet. A WAF can detect and block common web attacks, such as buffer overflows, SQL injections, cross-site scripting (XSS), and more. A WAF can also enforce security policies and rules, such as input validation, output encoding, and encryption. A WAF can provide a layer of protection for the web application, preventing attackers from exploiting its vulnerabilities and compromising its data. References = Buffer Overflows – CompTIA Security+ SY0-701 – 2.3, Web Application Firewalls – CompTIA Security+ SY0-701 – 2.4, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]

Full packet capture is a technique that records all network traffic passing through a device, such as a router or firewall. It allows for detailed analysis and investigation of network events, such as SQLi attacks, by providing the complete content and context of the packets. Full packet capture can help identify the source, destination, payload, and timing of an SQLi attack, as well as the impact on the server and database. Logging NetFlow traffic, network traffic sensors, and endpoint and OS-specific security logs can provide some information about network activity, but they do not capture the full content of the packets, which may limit the scope and depth of the investigation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 372-373

VM escape allows an attacker to break out of a virtual machine to access the hypervisor or other adjacent virtual machines on the same host, effectively moving laterally to adjacent systems.

Side loading (B) involves loading malicious code in place of legitimate components. Remote code execution (C) allows running arbitrary code remotely. Resource exhaustion (D) causes denial of service by overusing resources.

VM escape is a known virtualization vulnerability detailed in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

A firewall ACL (access control list) is a set of rules that determines which traffic is allowed or denied by the firewall. The rules are processed in order, from top to bottom, until a match is found. The syntax of a firewall ACL rule is:

Access list

To limit outbound DNS traffic originating from the internal network, the firewall ACL should allow only the device with the IP address 10.50.10.25 to send DNS requests to any destination on port 53, and deny all other outbound traffic on port 53. The correct firewall ACL is:

Access list outbound permit 10.50.10.25/32 0.0.0.0/0 port 53 Access list outbound deny 0.0.0.0/0 0.0.0.0/0 port 53

The first rule permits outbound traffic from the source address 10.50.10.25/32 (a single host) to any destination address (0.0.0.0/0) on port 53 (DNS). The second rule denies all other outbound traffic on port 532.

A watering-hole attack is a type of cyberattack that targets groups of users by infecting websites that they commonly visit. The attackers exploit vulnerabilities to deliver a malicious payload to the organization’s network. The attack aims to infect users’ computers and gain access to a connected corporate network. The attackers target websites known to be popular among members of a particular organization or demographic. The attack differs from phishing and spear-phishing attacks, which typically attempt to steal data or install malware onto users’ devices1

In this scenario, the compromised industry blog is the watering hole that the attackers used to spread malware across the company’s network. The attackers likely chose this blog because they knew that the employees of the company were interested in its content and visited it frequently. The attackers may have injected malicious code into the blog or redirected the visitors to a spoofed website that hosted the malware. The malware then infected the employees’ computers and propagated to the network.

Firmware is a type of software that is embedded in a hardware device, such as a router, a printer, or a BIOS chip. Firmware controls the basic functions and operations of the device, and it can be updated or modified by the manufacturer or the user. Firmware version is a hardware-specific vulnerability, as it can expose the device to security risks if it is outdated, corrupted, or tampered with. An attacker can exploit firmware vulnerabilities to gain unauthorized access, modify device settings, install malware, or cause damage to the device or the network. Therefore, it is important to keep firmware updated and verify its integrity and authenticity. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 67.

A Host-based Intrusion Prevention System (HIPS) acts as a preventive control by actively blocking threats and a detective control by monitoring and alerting to suspicious activities on endpoints.

An evil twin attack involves setting up a fraudulent Wi-Fi access point that mimics a legitimate one to intercept network traffic or steal credentials. This attack exploits insecure wireless networks and is focused on network infrastructure.

Impersonation, watering hole, and pretexting are social engineering or web-based attacks, not primarily network attacks.

The evil twin attack is a well-known wireless threat discussed under Threats and Vulnerabilities in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Web-based administration is a feature that allows users to configure and manage routers through a web browser interface. While this feature can provide convenience and ease of use, it can also pose a security risk, especially if the web interface is exposed to the internet or uses weak authentication or encryption methods. Web-based administration can be exploited by attackers to gain unauthorized access to the router’s settings, firmware, or data, or to launch attacks such as cross-site scripting (XSS) or cross-site request forgery (CSRF). Therefore, disabling web-based administration is a good practice to harden the routers within the corporate network. Console access, routing protocols, and VLANs are other features that can be configured on routers, but they are not the most appropriate to disable for hardening purposes. Console access is a physical connection to the router that requires direct access to the device, which can be secured by locking the router in a cabinet or using a strong password. Routing protocols are essential for routers to exchange routing information and maintain network connectivity, and they can be secured by using authentication or encryption mechanisms. VLANs are logical segments of a network that can enhance network performance and security by isolating traffic and devices, and they can be secured by using VLAN access control lists (VACLs) or private VLANs (PVLANs).

Acknowledgement and attestationinvolveformal confirmationthat an application is no longer in scope for compliance, auditing, or reporting requirements. This typically includes documentation signed by relevant stakeholders confirming that the software no longer processes, stores, or transmits relevant data.

Data inventory and retention (A)is related to managing data assets, not software scope confirmation.

Right to be forgotten (B)pertains toprivacy laws (e.g., GDPR), allowing individuals to request data deletion.

Due care and due diligence (C)focus on security best practices rather than software applicability.

The least privilege principle states that users and processes should only have the minimum level of access required to perform their tasks. This helps to prevent unauthorized or unnecessary actions that could compromise security. In this case, the patch transfer might be failing because the user or process does not have the appropriate permissions to access the critical system or the network resources needed for the transfer. Applying the least privilege principle can help to avoid this issue by granting the user or process the necessary access rights for the patching activity. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 931

Safety controls are security controls that are designed to protect human life and physical assets from harm or damage. Examples of safety controls include fire alarms, sprinklers, emergency exits, backup generators, and surge protectors. Safety controls should fail open, which means that they should remain operational or allow access when a failure or error occurs. Failing open can prevent or minimize the impact of a disaster, such as a fire, flood, earthquake, or power outage, on human life and physical assets. For example, if a fire alarm fails, it should still triggerthe sprinklers and unlock the emergency exits, rather than remain silent and locked. Failing open can also ensure that essential services, such as healthcare, transportation, or communication, are available during a crisis. Remote access points, logging controls, and logical security controls are other types of security controls, but they should not fail open in a data center. Remote access points are security controls that allow users or systems to access a network or a system from a remote location, such as a VPN, a web portal, or a wireless access point. Remote access points should fail closed, which means that they should deny access when a failure or error occurs. Failing closed can prevent unauthorized or malicious access to the data center’s network or systems, such as by hackers, malware, or rogue devices. Logging controls are security controls that record and monitor the activities and events that occur on a network or a system, such as user actions, system errors, security incidents, or performance metrics. Logging controls should also fail closed, which means that they should stop or suspend the activities or events when a failure or error occurs. Failing closed can prevent data loss, corruption, or tampering, as well as ensure compliance with regulations and standards. Logical security controls are security controls that use software or code to protect data and systems from unauthorized or malicious access, modification, or destruction, such as encryption, authentication, authorization, or firewall. Logical security controls should also fail closed, which means that they should block or restrict access when a failure or error occurs. Failing closed can prevent data breaches, cyberattacks, or logical flaws, as well as ensure confidentiality, integrity, and availability of data and systems.

Comprehensive and Detailed Explanation From Exact Extract:

Endpoint protection systems rely on policy rules, signatures, behavioral analytics, and heuristics. When the analyst identifies the event as a false positive, this indicates the file itself was not malicious, but the endpoint protection solution incorrectly identified it as a threat. According to CompTIA Security+ SY0-701 concepts, false positives commonly occur due to overly aggressive configuration settings, outdated rules, unrefined behavioral baselines, or incorrect threat signatures.

Zero-day vulnerabilities (B) would cause a true positive because the file contains unknown malware, not a false alert. A supply chain attack (C) would impact the vendor or update delivery, not a user download event. Incorrect file permissions (D) prevent access but do not trigger malware alerts.

Misconfigurations are identified in SY0-701 under Security Operations → Monitoring, alerting, tuning, and false positives, which emphasizes the need for refining security controls to reduce erroneous blocks. Therefore, the most likely cause of a blocked benign download is a misconfigured endpoint protection policy.

A Virtual Private Network (VPN) is the best solution to allow remote employees secure access to company resources without interception concerns. A VPN establishes an encrypted tunnel over the internet, ensuring that data transferred between remote employees and the company is secure from eavesdropping.

Proxy server helps with web content filtering and anonymization but does not provide encrypted access.

NGFW (Next-Generation Firewall) enhances security but is not the primary tool for enabling remote access.

Security zone is a network segmentation technique but does not provide remote access capabilities​​​.

An endpoint detection and response (EDR) system is a security tool that monitors and analyzes the activities and behaviors of endpoints, such as computers, laptops, mobile devices, and servers. An EDR system can detect, prevent, and respond to various types of threats, such as malware, ransomware, phishing, and advanced persistent threats (APTs). One of the features of an EDR system is to block the automatic execution of downloaded programs, which can prevent malicious code from running on the endpoint when a user clicks on a link in a phishing message. This can reduce the impact of a phishing attack and protect the endpoint from compromise. Updating the EDR policies to block automatic execution of downloaded programs is a technical control that can mitigate the risk of phishing, regardless of the user’s awareness or behavior. Therefore, this is the best answer among the given options.

The other options are not as effective as updating the EDR policies, because they rely on administrative or physical controls that may not be sufficient to prevent or stop a phishing attack. Placing posters around the office to raise awareness of common phishing activities is a physical control that can increase the user’s knowledge of phishing, but it may not change their behavior or prevent them from clicking on a link in a phishing message. Implementing email security filters to prevent phishing emails from being delivered is an administrative control that can reduce the exposure to phishing, but it may not be able to block all phishing emails, especially if they are crafted to bypass the filters. Creating additional training for users to recognize the signs of phishing attempts is an administrative control that can improve the user’s skills of phishing detection, but it may not guarantee that they will always be vigilant or cautious when receiving an email. Therefore, these options are not the best answer for this question. References = Endpoint Detection and Response – CompTIA Security+ SY0-701 – 2.2, video at 5:30; CompTIA Security+ SY0-701 Certification Study Guide, page 163.
