Question 740
A risk review at a retail network focuses on preventing this issue again: An analyst creates a no-decrypt policy for an excluded URL but overlooks the rule position, so a higher decrypt rule still intercepts it. Which recurring control is most suitable?
Explanation
Correct Answer
Use rule precedence checks for exception lifecycle tests. This control reduces recurrence of the documented mechanism: Policy order governs which decryption action applies to a matching session. It creates a repeatable check around the needed response: Place the approved exclusion at the correct precedence and validate its matching conditions.
Incorrect Answers
Review jurisdictional and category-specific decryption exemptions during policy audits. That safeguard addresses another potential failure: A retail enterprise enables decryption on every financial-site connection, contrary to an approved privacy exemption for one regulated category. It is not the most targeted recurring control for the described cause: Policy order governs which decryption action applies to a matching session.
Inspect policy ordering and no-decrypt exceptions before rollout. That safeguard addresses another potential failure: A production decryption rule enables outbound SSL Forward Proxy for staff but a higher no-decrypt rule matches all Internet destinations. It is not the most targeted recurring control for the described cause: Policy order governs which decryption action applies to a matching session.
Test decryption issuer and endpoint trust after any signing CA rotation. That safeguard addresses another potential failure: A certificate renewal makes firewall-generated forward-proxy chains untrusted by managed endpoints while unchanged security rules continue allowing traffic. It is not the most targeted recurring control for the described cause: Policy order governs which decryption action applies to a matching session.
