Question 680
During a post-incident review at a regional data center, the original problem was: A medical application fails under a newly broad decryption policy because it rejects forward-proxy re-signing. Which preventive practice most directly addresses its cause?
Explanation
Correct Answer
Record decryption exception business owner and revalidation interval. This control reduces recurrence of the documented mechanism: Certificate-pinning applications may reject proxy certificates even when the policy otherwise matches. It creates a repeatable check around the needed response: Create a tightly controlled decryption exception only for the verified incompatible application flow.
Incorrect Answers
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: Certificate-pinning applications may reject proxy certificates even when the policy otherwise matches.
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: Certificate-pinning applications may reject proxy certificates even when the policy otherwise matches.
Reconcile certificate custody and renewal with inbound decryption policy. That safeguard addresses another potential failure: A bank enables inbound TLS inspection for a public service without importing an authorized server certificate and private key as required for the selected method. It is not the most targeted recurring control for the described cause: Certificate-pinning applications may reject proxy certificates even when the policy otherwise matches.
