The scenario describes distributed scraping where each individual IP stays below request-rate thresholds. A simple DoS threshold is weak here because the attacker avoids volume-based detection per source. Static blocklists are also ineffective because many botnet IPs may appear only once or rotate frequently. Blocking every non-allowlisted user agent would cause severe false positives and is easy for bots to evade by spoofing headers. FortiWeb bot mitigation is the correct control because it can evaluate behavior beyond source IP volume. Device fingerprinting, browser behavior, headers, JavaScript challenges, and client characteristics help correlate suspicious automation even when requests are spread across many addresses. Therefore, bot mitigation with behavioral/device fingerprinting is the strongest answer.

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

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.

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.

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.

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

FortiWeb machine learning uses layered detection rather than treating every unusual value as malicious. The HMM layer models normal parameter behavior and can flag a value as abnormal when it falls outside the learned distribution. However, abnormal does not automatically mean hostile. FortiWeb then uses additional ML classification logic, including SVM-based evaluation, to determine whether the anomaly resembles an actual attack or simply a legitimate unusual input. In this case, HMM noticed that the value was uncommon, but SVM classified it as normal, so FortiWeb allowed the request. That is expected behavior. Raising thresholds, disabling models, or assuming FortiWeb failed would misunderstand the two-stage ML decision process.
