NSE5_FWB_AD-8.0 Fortinet NSE 5 - FortiWeb 8.0 Administrator Question and Answers

The goal is to detect bots that avoid normal human interaction, specifically mouse use and clicking, while logging the event and treating it as high severity. In FortiWeb biometrics-based bot detection, monitored client events such as mouse movement, click, keyboard, screen touch, page focus, and scroll help FortiWeb distinguish human behavior from automated behavior. Since the question specifically mentions mouse and clicking, the correct monitored events are Mouse Movement and Click . The current action is Deny (no log) , which would not meet the logging requirement. Changing the action to Alert logs the event instead of silently denying it, and setting severity to High aligns with the requirement for a high-severity alert.

True transparent proxy mode is the correct fit when the organization cannot change the current IP addressing or client-server communication flow. In this mode, FortiWeb is deployed transparently in the traffic path, usually using a Layer 2 bridge or v-zone, so clients still send traffic to the original web server IP address rather than to a FortiWeb virtual server IP. Unlike transparent inspection, true transparent proxy mode can more reliably block malicious traffic inline before forwarding it to the server. Reverse proxy mode normally requires clients or upstream devices to send traffic to FortiWeb’s virtual server address. WCCP requires redirection design changes. Decryption mirror mode is mainly passive inspection and is not the best answer for inline blocking.

Traffic logging is more storage-intensive than normal event or attack logging, so FortiWeb does not always expose policy traffic-log selection by default. The Study Guide states that traffic logs must be enabled from the CLI before they can be selected in a server policy. This matches the exhibit: the administrator is in the server policy wizard but cannot see the traffic log option. FortiAnalyzer or FortiSIEM can receive logs, but they do not make the policy option appear. Deployment mode is also not the determining factor here. FortiAppSec Cloud licensing is unrelated. The correct cause is that global traffic logging must first be enabled manually through the CLI, after which policy-based traffic logging can be selected.

A WAF such as FortiWeb is specifically built to protect web applications and web servers from HTTP and HTTPS application-layer attacks. SQL injection and cross-site scripting are Layer 7 threats that exploit web application input handling, not general network-layer forwarding. FortiWeb inspects HTTP/S requests, applies attack signatures, protocol validation, parameter validation, and other web protection controls to detect malicious payloads before they reach the protected application. Option A is wrong because protecting user browsers is mainly endpoint or client security, not WAF server-side protection. Option B is too generic and describes network firewall or IPS-style inspection rather than web application firewall enforcement. The two correct WAF actions are detecting Layer 7 attacks and analyzing HTTP/S requests targeting the web server.

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

The ABP workflow begins when FortiWeb challenges the browser by injecting JavaScript used to collect behavior data. The client browser then executes that JavaScript and sends the observed behavior information to the ABP service. FortiWeb then uses the ABP service decision process to determine whether the browser behavior looks human or automated. If the ABP service identifies the activity as malicious or bot-like, FortiWeb blocks the request before it reaches the protected application. If the request is validated as coming from a real user, FortiWeb allows the traffic to continue to the back-end server. The order is important because FortiWeb cannot allow or block based on ABP until browser behavior has first been collected and evaluated.

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

When multiple HTTPS applications share one public IP address, the client begins the TLS connection and includes the requested hostname in the SNI field. FortiWeb uses SNI-based certificate selection to choose the appropriate certificate for that hostname. After presenting the correct certificate and completing the TLS handshake, FortiWeb decrypts the HTTPS session so it can inspect HTTP content. Content inspection then evaluates the host header and URL path, which are needed for application-aware routing decisions. Finally, intelligent traffic routing forwards the request to the correct back-end server or server pool. The sequence matters: FortiWeb cannot inspect the host and URL path or route by content until the HTTPS session is terminated and decrypted.

To validate HA synchronization, the administrator should compare the configuration areas that affect traffic handling and security enforcement. Network configuration, such as interface and routing alignment, is important because HA peers must process traffic consistently. Policy configuration is also critical because server policies, protection profiles, rules, and related web security settings determine how FortiWeb inspects and blocks requests. Logs are not the right synchronization target for this question; log files are used for investigation, not for proving configuration synchronization. Firmware images and upgrade history are also not the normal operational configuration areas used to verify HA policy behavior. The correct verification focus is network configuration consistency and web protection/server policy consistency across the HA cluster.
