Paloalto Networks Updated PCNSE Exam Questions and Answers by aysha

If some sites cannot be decrypted due to technical reasons, such as unsupported ciphers, and blocking them is not an option, then the engineer should add the sites to the SSL Decryption Exclusion list to exempt them from decryption. The SSL Decryption Exclusion list is a predefined list of sites that are not subject to SSL decryption by the firewall. The list includes sites that use certificate pinning, mutual authentication, or unsupported cipher suites. The engineer can also add custom sites to the list if they have a valid business reason or technical limitation for not decrypting them34. Adding the sites to the SSL Decryption Exclusion list will allow the traffic to pass through without being decrypted or blocked by the firewall. References: SSL Decryption Exclusion, Troubleshoot Unsupported Cipher Suites

For HIP match logs to be visible on the data center firewall, the following conditions must be met:

HIP profiles added to security rules: HIP profiles must be applied to security rules on the data center firewall to enforce access restrictions based on the received HIP reports. If the HIP profiles are not associated with the security rules, the firewall will not evaluate traffic against these profiles, and consequently, no HIP match logs will be generated.

User-ID enabled on the incoming zone: User-ID must be enabled on the zone where the users are located in the data center firewall. The User-ID feature is responsible for mapping IP addresses to user names, which is critical for applying policies based on user identity and, by extension, for HIP-based policy enforcement.

The other options (A and D) are related to logging and log forwarding but would not directly impact the generation or visibility of HIP match logs on the data center firewall itself.

Decryption Mirror is a feature that allows a Palo Alto Networks firewall to send a copy of decrypted traffic to an external security device or tool for further analysis. The potential risk associated with Decryption Mirror is that if the firewall administrator's credentials are compromised, a malicious user could potentially access sensitive decrypted information. Hence, it's advised to be cautious and ensure proper handling of this feature.

Additionally, laws and regulations regarding the decryption, storage, inspection, and use of SSL/TLS encrypted traffic vary by country and industry. It is crucial to ensure compliance with relevant laws and best practices when using Decryption Mirror. This often requires consultation with corporate legal counsel to understand the implications and ensure that the use of such features does not violate privacy laws or regulatory requirements.

The need for administrative consent and the legal implications of using Decryption Mirror features are outlined in Palo Alto Networks' "PAN-OS® Administrator’s Guide" and best practice documentation. It is not specifically required to have a tap interface to use Decryption Mirror, which eliminates option A. Option C is incorrect because it is not just management consent but legal compliance that needs to be considered.
