Question 610
At Oakridge Public Services, the municipal network protection team administers FortiGate-based protection for citizen services and remote public offices under requirements for restricted data exchange and defensible access policy. Following the approved change, the team must validate: An IPS sensor is set to monitor a high-confidence threat signature but the approved policy requires preventing that traffic. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
A safe controlled signature test is denied and the IPS event identifies the selected block action and policy. This outcome validates the intended correction for: An IPS sensor is set to monitor a high-confidence threat signature but the approved policy requires preventing that traffic. The associated approved corrective action is: Change the targeted signature action to block in the matching IPS sensor and retain audit logging. The Oakridge Public Services reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The relevant controlled application event is detected under the proper inspection path without claiming certificate-only visibility into payload bytes. This would verify a separate corrective action: Validate the visibility needed by the intended application signature and configure supported deep inspection only for authorized managed endpoints. That separate change addresses: An administrator expects application-control rules to detect a specific command within encrypted HTTPS traffic under certificate-only inspection. It does not validate the current Oakridge Public Services issue: An IPS sensor is set to monitor a high-confidence threat signature but the approved policy requires preventing that traffic. The relevant acceptance evidence is: A safe controlled signature test is denied and the IPS event identifies the selected block action and policy.
The approved collaboration flow works while a separate prohibited application in the same category remains blocked. This would verify a separate corrective action: Create a narrowly scoped application override for the approved signature, users and destinations without disabling the rest of the sensor. That separate change addresses: A help desk creates an unrestricted application-control exception for a single business collaboration app and unintentionally bypasses the whole category. It does not validate the current Oakridge Public Services issue: An IPS sensor is set to monitor a high-confidence threat signature but the approved policy requires preventing that traffic. The relevant acceptance evidence is: A safe controlled signature test is denied and the IPS event identifies the selected block action and policy.
An approved server with a complete chain passes inspection while a deliberately invalid certificate is still reported and denied. This would verify a separate corrective action: Keep upstream certificate validation enabled and remediate the specific trust chain or narrowly authorized exception. That separate change addresses: An administrator changes the SSL inspection profile to disable all certificate validation after encountering one untrusted upstream server. It does not validate the current Oakridge Public Services issue: An IPS sensor is set to monitor a high-confidence threat signature but the approved policy requires preventing that traffic. The relevant acceptance evidence is: A safe controlled signature test is denied and the IPS event identifies the selected block action and policy.
