Question 360
At the Thornfield retail company, the firewall logs a known exploit signature but does not block the connection because the action is alert-only. Which ongoing control best prevents this issue from recurring?
Explanation
Correct Answer
The continuing safeguard is to review intrusion rule overrides and threat intelligence changes. It helps avoid the original condition: an alerting-only signature does not enforce packet prevention.
Incorrect Answers
Monitor file-disposition updates and inspection coverage. That safeguard would help prevent recurrence of: Network permission to connect does not imply all transferred file content is safe. The risk being reviewed here is instead: An alerting-only signature does not enforce packet prevention. The matching ongoing control is: Review intrusion rule overrides and threat intelligence changes.
Review client certificate expiry and revocation handling is not the primary recurring safeguard for this problem. The team should review intrusion rule overrides and threat intelligence changes. For the Thornfield retail company, the direct corrective action is to apply the intended intrusion policy and tested blocking disposition to matching traffic.
Revalidate internal application flows whenever a workload moves. That safeguard would help prevent recurrence of: Perimeter inspection does not monitor or restrict movement between internal workloads. The risk being reviewed here is instead: An alerting-only signature does not enforce packet prevention. The matching ongoing control is: Review intrusion rule overrides and threat intelligence changes.
