PCNSE Exam Dumps - Paloalto Networks Palo Alto Certifications and Accreditations Questions and Answers

The compare option for a specific rule in the New App Viewer under Policy Optimizer allows an administrator to compare the applications configured in the rule with the applications seen from traffic matching the same rule. This helps the administrator to identify any new applications that are not explicitly defined in the rule, but are implicitly allowed by the firewall based on the dependencies of the configured applications. The compare option also shows the usage statistics and risk levels of the applications, and provides suggestions for optimizing the rule by adding, removing, or replacing applications12. References: New App Viewer (Policy Optimizer), PCNSE Study Guide (page 47)

To configure SSL Forward Proxy decryption on a Palo Alto Networks firewall, certain key components must be set up to ensure secure and effective decryption and inspection of SSL/TLS encrypted traffic:

B. Define a Forward Trust Certificate:

A Forward Trust Certificate is essential for SSL Forward Proxy decryption. This certificate is used by the firewall to dynamically generate certificates for SSL sites that are trusted. When the firewall decrypts and inspects the traffic and then re-encrypts it, the new certificate presented to the client comes from the Forward Trust Certificate authority. This certificate must be trusted by client devices, often requiring the Forward Trust CA certificate to be distributed and installed on client devices.

C. Configure SSL decryption rules:

SSL decryption rules are the policies that determine which traffic is to be decrypted. These rules specify the source, destination, service, and URL category, among other criteria. The rules define what traffic the SSL Forward Proxy will apply to, enabling selective decryption based on security and privacy requirements.

Together, these components form the basis of the SSL Forward Proxy decryption setup, allowing for the decryption, inspection, and re-encryption of SSL/TLS encrypted traffic to identify and prevent threats hidden within encrypted sessions.
