An administrator has configured SSL Forward Proxy decryption for outbound internet traffic on a Palo Alto Networks NGFW They want to exclude a specific application internal-app') running on HTTPS (port 443) from decryption because it uses client-side certificates. The 'internal-app' is hosted externally but accessed by internal users. There is a general 'Decrypt all outbound HTTPS' rule lower in the policy. Which configuration steps are necessary to create the exclusion rule?
Correct Answer: A
Exclusions in Decryption policy are achieved using 'No Decrypt' rules placed strategically. - Option A (Correct): This is the correct method. You create a separate rule in the Decryption Policy that specifically matches the traffic you want to exclude (based on source/destination zones, the specific application, etc.) and set the action to 'No Decrypt'. Placing this rule above the broader 'Decrypt' rule ensures that this specific traffic is evaluated and exempted from decryption before the general decryption rule is encountered. - Option B: 'No Decrypt' is a Decryption Policy action, not a Security Policy action. - Option C: While some policies allow specific exclusions within a rule, the standard and more flexible method for defining broad exceptions based on multiple criteria is through separate 'No Decrypt' rules. - Option D: Decryption Profiles handle error actions and unsupported parameters, not lists of URLs to exclude from decryption policy matching itself. - Option E: Removing 'SSI' from the decrypt rule would prevent decryption for all HTTPS traffic, not just the specific application. Using separate rules for applications is valid in Security Policy but the exclusion itself is configured in the Decryption Policy.
