Managing-Cloud-Security WGU Managing Cloud Security (JY02) Question and Answers

This is an example ofsocial engineering, where attackers manipulate individuals into divulging confidential information or performing actions that compromise security. In this case, the fraudulent caller convinced the help desk to disclose sensitive employee data.

Man-in-the-middle attacks involve intercepting communication between parties, escalation of privilege involves gaining higher access rights, and internal threats come from legitimate insiders. None of these fit the situation as accurately as social engineering.

Social engineering exploits human trust rather than technical vulnerabilities. Common tactics include phishing, pretexting, and phone-based fraud (vishing). Preventing such threats requires strong identity verification processes, employee awareness training, and layered authentication mechanisms. By recognizing the human element as a weak point, organizations can better prepare staff to resist manipulative tactics.

Dedicated memoryallocation ensures isolation between virtual machines in a shared environment. Without memory isolation, remnants of one VM’s operations might remain in physical memory and be accessible to another VM, leading to cross-tenant data leakage. Assigning dedicated memory prevents attackers from exploiting memory-sharing vulnerabilities.

Encrypted network protocols protect data in transit, not memory. Encrypted file systems safeguard storage, not volatile memory. A dedicated processor helps with performance and isolation of compute tasks but does not secure temporary memory contents.

Cloud environments are multi-tenant, which makes memory isolation a critical safeguard. By dedicating memory or enforcing strict hypervisor-level isolation, providers prevent data exposure between customers. This aligns with best practices for virtualization security and the “resource pooling” characteristic of cloud computing, ensuring that shared infrastructure does not compromise confidentiality.

Thenetworkis the component that enables customers to transfer data into and out of a cloud environment. It provides the connectivity through which data is uploaded, downloaded, and exchanged between customer systems and cloud infrastructure.

Firewalls protect the network by filtering traffic, load balancers distribute requests across resources, and virtual displays present interfaces, but none directly facilitate the transfer of data.

In cloud models, secure networking is critical. Protocols like TLS encrypt traffic, while VPNs and private links provide additional isolation. Reliable networking ensures availability, while strong controls safeguard confidentiality and integrity. Customers must ensure that the cloud provider offers secure, high-performance network services to support business needs.

Agileis an iterative software development methodology designed to prioritize customer satisfaction, adaptability, and incremental delivery. Agile teams deliver small, working pieces of software frequently, ensuring feedback is incorporated throughout the process. This flexibility allows late-stage requirement changes to be accommodated without derailing the project.

Waterfall is a sequential approach with limited flexibility. Spiral combines iterative development with risk analysis, but it is not as customer-focused as Agile. Lean emphasizes efficiency and waste reduction but does not center on continuous delivery and adaptability.

Agile frameworks such as Scrum and Kanban embody this philosophy, supporting faster innovation, better collaboration, and responsiveness to evolving business needs.

A cloud service partner plays a complementary role by offering products or services that enhance or interact with the primary cloud provider’s offerings. Examples include managed service providers, value-added resellers, or software vendors that integrate their solutions with the core infrastructure or platform of a cloud service provider.

The customer is the end user of cloud services, regulators ensure compliance with laws, and developers create applications but do not represent an independent ecosystem role. Partners, on the other hand, extend the value of the primary offering by providing additional tools, support, or integrations that enhance customer experience.

This ecosystem role is recognized by major cloud frameworks, such as the Cloud Security Alliance, which notes the importance of partners in ensuring interoperability, extending services, and supporting shared responsibility. For customers, this means greater flexibility and choice in tailoring cloud solutions to business needs.

The most effective way to protect network traffic from interception isTransport Layer Security (TLS). TLS provides confidentiality, integrity, and authentication by encrypting data as it travels between client and server. Unlike older protocols like SSL, which is now deprecated due to vulnerabilities, TLS is the industry-standard protocol endorsed by modern security frameworks.

Compression and password protection through GZ is not a reliable method, as it does not offer strong encryption or resistance against sophisticated interception attacks. GRE is a tunneling protocol and does not inherently provide encryption.

By implementing TLS, organizations ensure protection against on-path attacks, replay attacks, and packet sniffing. TLS also supports features such as forward secrecy and certificate-based authentication, ensuring both secure data transmission and mutual trust between endpoints. In compliance-driven industries like healthcare and finance, TLS is explicitly mandated for protecting sensitive information in transit.

Infrastructure as a Service (IaaS) delivers fundamental computing resources over the cloud. These include virtual machines, block storage, networking, and load balancers. Customers use these resources to build and manage custom IT solutions, while the provider manages the underlying hardware.

PaaS abstracts infrastructure further, providing a development environment for applications without requiring infrastructure management. SaaS delivers fully functional applications over the internet. NaaS is a narrower category focusing on network delivery.

IaaS is the correct answer because it gives maximum flexibility and control compared to the other models, allowing organizations to build tailored environments. It also requires customers to manage operating systems, middleware, and runtime security, making shared responsibility an essential part of the model.

Continuous auditingin the context of Information Rights Management (IRM) allows organizations to monitor access events in real time. It records who accessed a file, when, and how often. This enables organizations to enforce accountability and detect unusual access patterns, which are crucial for both security monitoring and compliance reporting.

Automatic expiration sets a time limit on file availability, while dynamic policy control adjusts permissions based on context (such as location or device). Persistent protection ensures files remain encrypted and controlled wherever they travel. While each feature is valuable, only continuous auditing provides the tracking and visibility into usage required by the scenario.

This approach aligns with governance requirements, providing an audit trail that supports incident response and compliance with data protection regulations. Continuous auditing strengthens both operational security and accountability.

The correct contractual safeguard is anescrow agreement. Data escrow involves storing critical data or software with a neutral third party, which can release it to the customer if the provider fails to meet obligations, such as bankruptcy or service discontinuation.

Indemnification covers liability, offboarding manages termination processes, and encryption secures data but does not ensure availability if the provider disappears.

Escrow provisions protect business continuity by guaranteeing customer access to data regardless of provider viability. They are especially important for organizations handling mission-critical workloads or long-term regulatory obligations in the cloud.

TheAssurancesection of a contract specifies the customer’s rights to verify that the vendor is meeting contractual and compliance obligations. This often includes the right to audit, request independent certifications, or require compliance reports such as SOC 2 or ISO 27001.

Indemnification deals with liability coverage, termination outlines exit conditions, and litigation describes dispute resolution mechanisms. None of these provide the customer with ongoing oversight rights.

Audit rights are critical in cloud contracts to maintain transparency, enforce accountability, and verify that shared responsibility is being upheld. Assurance provisions give customers confidence in the provider’s security and operational practices, ensuring compliance with industry regulations.

Indirect identifiersare pieces of information that may not identify an individual on their own but, when combined with other data, can uniquely identify someone. Examples include birthdate, ZIP code, or gender. Together, these can re-identify a person, even when names or direct identifiers are removed.

Direct identifiers (such as Social Security numbers) uniquely identify an individual alone. Data subjects are the individuals to whom the data refers, while personal details is too broad and not a formal term.

Understanding indirect identifiers is essential in privacy regulations like GDPR and HIPAA, where pseudonymization or anonymization must account for potential re-identification risks. Safeguarding indirect identifiers reduces the chance of privacy violations and unauthorized profiling.

TheSarbanes-Oxley (SOX) Act of 2002was enacted to restore investor confidence after major corporate accounting scandals. It requires publicly traded corporations to maintain accurate financial reporting and implement internal controls to safeguard the integrity of disclosed information.

GLBA focuses on protecting consumer financial data, GDPR is a European regulation governing privacy, and the CLOUD Act addresses cross-border law enforcement access to data. Only SOX directly mandates financial disclosure and corporate accountability.

SOX compliance includes maintaining audit trails, securing data integrity, and ensuring that executives certify financial statements. Failure to comply carries severe penalties, both civil and criminal. For cloud environments, SOX compliance extends to ensuring IT systems used for financial data are secure, monitored, and auditable.

Thecomputecomponent of a cloud platform encompasses resources used to run workloads, includingcontainers, virtual machines, and storage tied directly to those workloads. Compute services are the foundation of cloud infrastructure, enabling execution of applications and management of data.

Security, monitoring, and networking are supporting components but do not include execution environments. Compute resources scale elastically, allowing organizations to match demand and optimize cost.

By combining containers and storage within compute, cloud platforms allow rapid deployment, portability, and isolation of applications. This component underpins modern architectures like Kubernetes and serverless computing, providing agility and efficiency.

Theprocurementfunction is directly responsible for vendor selection and contract management, including risk assessments of new or renewed vendor relationships. This ensures that third-party providers meet security, compliance, and performance requirements.

Software development and quality assurance focus on product creation and validation. Marketing manages branding and outreach. None of these directly involve evaluating external vendor risk.

Procurement integrates due diligence, contract clauses, and performance monitoring into enterprise risk management. This reduces exposure to third-party threats and ensures compliance with frameworks such as ISO 27036 (supplier relationships) and NIST vendor risk management guidelines.

Arollbackis the safeguard that restores a system to its previous, stable state when a new code release introduces issues. In DevOps workflows, rollbacks provide a rapid recovery mechanism, reducing downtime and minimizing customer impact.

Staging, code review, and testing are preventive controls that reduce the likelihood of defects reaching production, but once a bug has already been deployed, rollback is the corrective control.

Rollback strategies often rely on version control systems, container orchestration, or infrastructure-as-code automation to quickly revert to earlier configurations. This practice is essential for maintaining reliability and availability, especially in cloud environments with continuous deployment pipelines.

The engineers are concerned aboutportability. Vendor-specific APIs and tools create a dependency on a single provider, leading to vendor lock-in. This limits the ability to migrate services or workloads to another provider without significant rework.

Reliability and availability refer to service uptime and continuity, while scalability addresses performance under demand. Although important, none of these directly relate to cross-platform flexibility. Portability ensures that services, data, and applications can be easily moved or integrated across environments.

By adopting portable solutions—such as open standards, containerization, and multi-cloud strategies—organizations reduce long-term risks, increase negotiation power with providers, and enhance resilience.

TheChange Management Board (CMB), also called the Change Advisory Board (CAB), is the formal authority responsible for reviewing, assessing, and approving planned modifications to IT environments. This group ensures that proposed changes align with business objectives, do not introduce unnecessary risks, and comply with security and regulatory requirements.

Event management teams focus on monitoring events, problem management teams handle root-cause analysis, and executive boards provide strategic direction but are not operational approval authorities. Only the CMB has the explicit role of validating technical and security implications before implementation.

By involving the CMB, organizations enforce structured governance, minimize disruptions, and establish accountability. This practice is central in ITIL and ISO/IEC 20000 standards, ensuring that operational integrity and security are preserved during change cycles.

Resource pooling is one of the core characteristics of cloud computing defined by NIST. It refers to the provider’s ability to serve multiple customers by dynamically allocating and reallocating computing resources such as storage, processing, memory, and network bandwidth. These resources are abstracted using virtualization, ensuring that customers remain isolated from one another even though they share the same physical assets.

Rapid scalability describes elasticity, on-demand self-service allows users to provision resources without provider intervention, and measured service refers to metering usage. None of these concepts directly describe the multi-tenant model of shared resources.

Resource pooling improves efficiency, reduces costs, and provides flexibility, but it also introduces new security considerations such as data isolation and hypervisor security. Customers must ensure that providers implement strong controls to prevent data leakage or cross-tenant compromise.

TheZero Trustsecurity model assumes that no user, device, or application should be trusted by default, whether inside or outside the network perimeter. Every access request must be continuously verified using strict identity, authorization, and context-based checks.

Unlike traditional perimeter security, Zero Trust emphasizes the principle of “never trust, always verify.” Traffic inspection looks at data packets, intrusion prevention identifies malicious activity, and secret management safeguards sensitive keys and credentials. None of these approaches enforce constant, adaptive identity verification the way Zero Trust does.

By adopting Zero Trust, organizations ensure that access is not granted simply because a user is “inside” the network. Instead, continuous checks evaluate credentials, device posture, location, and other risk factors. This significantly reduces the risk of insider threats, credential theft, and lateral movement within cloud environments.

The described scenario is aninjection attack. Injection occurs when unvalidated input—such as SQL commands, script code, or OS instructions—is sent to an application through API forms or parameters. If the application fails to sanitize input, the attacker’s code may be executed with full system privileges.

On-path attacks intercept communication, credential attacks target authentication, and denial-of-service floods services. None involve code execution via unvalidated input.

Injection is a top risk in OWASP API Security Top 10. Developers must implement input validation, parameterized queries, and least privilege principles to mitigate this risk. API gateways and WAFs provide additional layers of protection but cannot replace secure coding practices.

The correct answer iselectronic discovery (e-discovery). This process involves identifying, collecting, and producing electronically stored information (ESI) that may serve as evidence in legal proceedings. E-discovery ensures that relevant data such as emails, logs, or documents is preserved and made available in a legally defensible manner.

Chain of custody refers to documenting the handling of evidence once collected, while forensic imaging creates exact copies of digital media. Gap analysis identifies weaknesses in processes but is unrelated to evidence collection.

E-discovery is essential in both corporate and cloud contexts, as data is often distributed across multiple environments. Cloud providers may assist customers with e-discovery by providing tools for searching, tagging, and exporting relevant data. A sound e-discovery process ensures compliance with legal obligations and prevents spoliation of evidence.
