A FortiWeb server policy binds the listener, destination pool, and service handling required for traffic flow. The virtual server defines the public-facing listener where client traffic arrives. The server pool defines the real back-end servers or load-balanced pool where FortiWeb forwards accepted traffic. The service or port settings define whether FortiWeb handles HTTP, HTTPS, or another configured service. A WAF profile is important for security inspection, but the question asks for the three components needed to complete the forwarding policy. DNS resolver, URL rewrite, health checks, IPsec tunnels, and static routes may be useful in some deployments, but they are not the required core components of the server policy.

FortiWeb machine learning protection depends on observed application traffic. The administrator must first collect traffic samples so FortiWeb can learn normal behavior and create a useful baseline. After sample collection, FortiWeb uses the collected data to build the detection model. Once the model is built, it must be enabled or run in the live environment so FortiWeb can evaluate production requests and detect abnormal or bot-like behavior. Manual verification on test data only is not enough to activate the model for real traffic. Bayesian analysis is not the FortiWeb configuration step shown for this process; the platform handles model logic internally. The practical workflow is collection, model building, and live enforcement or detection.

The URL https://www.example.com/25.3.6/Browse/MediaData exposes internal application structure and what appears to be a version number. Revealing version information, framework paths, or internal directory names gives attackers useful reconnaissance data. Attackers can correlate exposed versions with known vulnerabilities and target the application more precisely. FortiWeb URL rewriting can reduce this risk by hiding or transforming sensitive internal URLs before users or scanners see them. The other URLs are normal-looking public paths or common application resources. A WordPress RSS feed may or may not be appropriate depending on business requirements, but it does not clearly expose internal versioned routing in the same way. The risky URL is the one containing 25.3.6/Browse/MediaData.

The layered browser-protection model separates prevention, runtime detection, and post-compromise mitigation. CORS protection belongs in the first stage because it restricts which origins can interact with protected resources, helping prevent unauthorized cross-origin access before exploitation occurs. Subresource integrity belongs in the second stage because it detects whether externally loaded scripts or resources have been modified at runtime by comparing them against expected integrity values. HTTP header-based protection belongs in the mitigation stage because security headers can limit the impact of browser-side compromise by controlling browser behavior, enforcing restrictions, and reducing exploit capability. The correct sequence is therefore CORS first, subresource integrity second, and HTTP header request last.

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

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.

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

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.

This is a stored cross-site scripting attack. The attacker submits JavaScript into a product review form, and the application stores and displays it later to other users. When victims view the review, their browsers execute the attacker’s script as if it came from the trusted site. That is dangerous because the script can access browser-side data available to the page, such as cookies, tokens, page content, or session-related information depending on browser and cookie security settings. It does not directly leak the back-end database; that would be more aligned with SQL injection. It also does not inherently bypass login pages or require the victim to click a link. The core risk is malicious code execution in the victim’s browser.

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

The mapping follows the security risk each FortiWeb feature mitigates. User Tracking maps to Broken Access Control because it helps enforce authenticated-session behavior and can prevent unauthorized access patterns. HSTS Header Security maps to Cryptographic Failures because it forces browsers toward HTTPS and reduces downgrade or weak transport behavior. Padding Oracle Protection also maps to Cryptographic Failures because padding oracle attacks exploit weaknesses in encrypted session or token handling. Web Vulnerability Scan maps to Security Misconfiguration because scans help expose misconfigured, exposed, or vulnerable application components. Session Forwarding fits Insecure Design because it helps enforce expected application flow rather than allowing users or attackers to jump through weakly designed paths.

FortiWeb bot mitigation is designed to distinguish automated clients from real human users by evaluating request behavior and browser interaction signals. Request-rate limits help detect automation patterns such as excessive requests over a short period, while mouse movement tracking is a behavioral or biometric-style control that helps confirm whether a browser session is being operated by a human. Blocking all unknown devices is too aggressive and would create major false positives. Disabling JavaScript for anonymous users would actually weaken behavior collection because FortiWeb uses JavaScript-based techniques in some bot workflows. Login-failure IP blocklists help against credential attacks, but they do not broadly identify nonhuman users. Therefore, request limits plus mouse movement tracking is the best answer.

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

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.
