Question 130
At a distributed branch estate, a test team is validating a change after this incident: An enterprise deploys an antivirus profile with an exception for one test signature but that exception is copied into the production profile without review. What evidence most directly verifies the intended outcome?
Explanation
Correct Answer
The exception inventory contains only approved exclusions and the relevant safe signature is handled as policy requires. This evidence directly tests the intended corrective action: Remove the unjustified exception or narrowly scope it under documented acceptance, then validate coverage. It confirms the failure mechanism—Signature-level exceptions can override otherwise restrictive profile defaults.—has been addressed in the actual affected flow.
Incorrect Answers
A controlled benign test confirms the rule references the full group and logs show each applicable inspection profile. This would verify resolution of a different case: A branch Security rule allows employee web browsing but attaches only URL Filtering, leaving malware downloads unscanned by its intended threat controls. It does not show that the reported issue was fixed or that its intended action—Remove the unjustified exception or narrowly scope it under documented acceptance, then validate coverage.—worked.
A safe validation signature is prevented with its associated threat event and no unrelated rules are changed. This would verify resolution of a different case: A Vulnerability Protection rule is configured only to alert for a known exploit signature despite policy requiring prevention of critical severity attacks. It does not show that the reported issue was fixed or that its intended action—Remove the unjustified exception or narrowly scope it under documented acceptance, then validate coverage.—worked.
Vendor access remains functional only for the approved scope and its allow traffic is inspected and logged. This would verify resolution of a different case: An emergency Security rule is placed above the normal rules without any attached security profiles, making it a broad inspection bypass for a temporary vendor. It does not show that the reported issue was fixed or that its intended action—Remove the unjustified exception or narrowly scope it under documented acceptance, then validate coverage.—worked.
