Question 210
At a retail network, a test team is validating a change after this incident: A branch TLS inspection setup accepts connections to servers with invalid certificates because the Decryption profile uses a permissive server-certificate failure action. What evidence most directly verifies the intended outcome?
Explanation
Correct Answer
A controlled invalid-chain site is handled according to the configured block or log requirement. This evidence directly tests the intended corrective action: Set the appropriate Decryption profile server-certificate checks to the approved failure behavior. It confirms the failure mechanism—A profile's certificate-validation actions determine whether untrusted server sessions proceed.—has been addressed in the actual affected flow.
Incorrect Answers
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—Set the appropriate Decryption profile server-certificate checks to the approved failure behavior.—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—Set the appropriate Decryption profile server-certificate checks to the approved failure behavior.—worked.
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—Set the appropriate Decryption profile server-certificate checks to the approved failure behavior.—worked.
