The Signature Matching layer provides pattern protection for spyware and vulnerability exploits. This layer uses single pass pattern matching to identify and block known threats effectively. Security processing focuses on policy enforcement and reporting rather than directly matching threat patterns, while network processing handles basic network operations.

The correct attributes selectable when setting up application filters are Category, Subcategory, Risk, Standard Ports, and Technology. These are the relevant attributes typically considered for configuring application filters as they provide a comprehensive overview that includes not just the categories and risks but also the standard ports and technology used by the applications.

In a URL filtering security profile, actions such as block, alert, continue, override, or allow can be set for specific categories of URLs. These categories are either custom URL categories, which administrators define to control access to particular URLs relevant to their organization's security policy, or PAN-DB URL categories, which are predefined URL categories provided by the PAN-DB database. Both types allow administrators to specify the desired actions based on organizational needs.

Updated application content might change how Security policy rules are enforced. This is because new App-IDs and modifications to existing App-IDs can cause the firewall to categorize and handle applications differently. Additionally, after an application content update, new applications are automatically identified and classified by the firewall. This automatic identification and classification reduces manual administrative effort and ensures that the security policies are up to date with the latest application signatures.
