Question 290
At a financial services branch, a test team is validating a change after this incident: A decryption exception is written for all finance subnets because one government portal cannot tolerate interception. What evidence most directly verifies the intended outcome?
Explanation
Correct Answer
Only documented exceptional sessions bypass inspection; other eligible flows continue to be inspected. This evidence directly tests the intended corrective action: Narrow the No Decrypt rule to the verified application or destination and retain decryption for unrelated finance traffic. It confirms the failure mechanism—A broad exception creates an unnecessary inspection blind spot beyond the problematic service.—has been addressed in the actual affected flow.
Incorrect Answers
A controlled inbound flow reaches the server and follows the intended decryption inspection path. This would verify resolution of a different case: An organization needs to inspect inbound HTTPS for an owned public server but configures SSL Forward Proxy instead of the appropriate inbound certificate-based model. It does not show that the reported issue was fixed or that its intended action—Narrow the No Decrypt rule to the verified application or destination and retain decryption for unrelated finance traffic.—worked.
The medical application remains functional while unrelated destination sessions no longer bypass inspection. This would verify resolution of a different case: An administrator excludes a medical service from decryption with an address object that includes adjacent unrelated business hosts. It does not show that the reported issue was fixed or that its intended action—Narrow the No Decrypt rule to the verified application or destination and retain decryption for unrelated finance traffic.—worked.
Session and decryption logs show the test flow matching the correct policy and inspection behavior. This would verify resolution of a different case: An analyst adds a Decryption profile but leaves the governing Decryption policy scoped to a different destination zone, resulting in no decryption for the tested traffic. It does not show that the reported issue was fixed or that its intended action—Narrow the No Decrypt rule to the verified application or destination and retain decryption for unrelated finance traffic.—worked.
