Palo Alto Networks Device Telemetry data, collected from firewalls with a device certificate installed, is stored on Palo Alto Networks Update Servers. This telemetry data includes information about threats, device health, and other operational metrics that are crucial for the continuous improvement of security services and threat intelligence. The collected data is anonymized and securely transmitted to Palo Alto Networks, where it is used to enhance the overall effectiveness of threat identification and prevention capabilities across all deployed devices. This collaborative approach helps in keeping the security ecosystem updated and resilient against emerging threats.

When implementing an application override in a Palo Alto Networks firewall, the primary goal is to explicitly define how specific traffic is identified and processed by the firewall, bypassing the regular App-ID process. This is particularly useful for traffic that might be misidentified by App-ID or for applications that require special handling for performance reasons.

To successfully implement application override, the following items must be configured:

B. Application override policy rule:This is a specialized policy rule that you create to specify the criteria for the traffic you want to override. In this rule, you define the source and destination zones, addresses, and ports. Instead of relying on the App-ID engine to identify the application, the firewall uses the criteria defined in the application override policy to classify the traffic.

C. Security policy rule:After defining an application override policy, you must also configure a security policy rule to allow the overridden traffic through the firewall. This rule specifies the action (allow, deny, drop, etc.) for the traffic that matches the application override policy. It's essential to ensure that the security policy rule matches the traffic defined in the application override policy to ensure that the intended traffic is allowed through the firewall.

For detailed guidance on configuring application override and the necessary security policies, refer to the official Palo Alto Networks documentation. This resource provides step-by-step instructions and best practices for effectively managing traffic using application overrides.

In Palo Alto Networks firewalls, the order of rule evaluation is critical for traffic enforcement. To ensure high priority evaluation, rules should be configured at the top of the rulebase so they are matched before others. The Security Pre-Rules are designed for shared policies across multiple device groups in Panorama, and by placing the block action rules at the top of the Pre-Rules, it guarantees that these rules are evaluated first, before any device-specific or post-rules.For verification, please refer to the Palo Alto Networks "PAN-OS® Administrator’s Guide" or the official configuration documentation for Panorama and device group rules.
