Question 490
At Redstone Aviation, the network engineering team administers FortiGate-based protection for approved aviation maintenance and scheduling networks under requirements for separated administrative flows and resilient site VPNs. Following the approved change, the team must validate: A security team mistakenly assumes an application-control block for a browser is equivalent to the web filter's URL category policy. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A category-specific controlled URL request is denied by web filtering while separate application-control rules are evaluated independently. This outcome validates the intended correction for: A security team mistakenly assumes an application-control block for a browser is equivalent to the web filter's URL category policy. The associated approved corrective action is: Use web filtering for category and URL decisions and application control for recognized application behavior under the intended policy. The Redstone Aviation reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
An authorized ordinary DNS resolution succeeds and a controlled disallowed encrypted-DNS client is blocked or explicitly audited. This would verify a separate corrective action: Evaluate supported application-control signatures or managed endpoint controls to restrict unauthorized encrypted DNS services. That separate change addresses: An application starts using encrypted DNS-over-HTTPS to evade approved DNS filtering and the firewall does not recognize its traffic type. It does not validate the current Redstone Aviation issue: A security team mistakenly assumes an application-control block for a browser is equivalent to the web filter's URL category policy. The relevant acceptance evidence is: A category-specific controlled URL request is denied by web filtering while separate application-control rules are evaluated independently.
A controlled nested test archive is evaluated according to the configured limit without exhausting firewall memory or CPU. This would verify a separate corrective action: Review supported archive scanning depth and resource constraints and apply an approved depth policy for the relevant traffic. That separate change addresses: A downloaded archive contains a harmless test detection nested inside it but the scanning policy has too restrictive an archive depth setting. It does not validate the current Redstone Aviation issue: A security team mistakenly assumes an application-control block for a browser is equivalent to the web filter's URL category policy. The relevant acceptance evidence is: A category-specific controlled URL request is denied by web filtering while separate application-control rules are evaluated independently.
A controlled oversized test transfer receives the documented action and log description without being mislabeled as fully scanned. This would verify a separate corrective action: Review supported oversized-file actions, protocol options and logging and apply the organization's fail-open or fail-closed decision. That separate change addresses: A file exceeds configured antivirus scanning limits and an analyst incorrectly reports it as fully inspected without reviewing oversized-file behavior. It does not validate the current Redstone Aviation issue: A security team mistakenly assumes an application-control block for a browser is equivalent to the web filter's URL category policy. The relevant acceptance evidence is: A category-specific controlled URL request is denied by web filtering while separate application-control rules are evaluated independently.
