PSE-Strata Leak Questions

When access to a business site is blocked by URL Filtering inline machine learning (ML) and it is identified as a false positive, the appropriate way to resolve this is to create a custom URL category and add the site to the exceptions list of the inline ML profile. This ensures that the specific URL is no longer subjected to the filtering rules applied by the inline ML, thereby allowing access to the site.

Creating a custom URL category and adding it to the exceptions of the inline ML profile ensures that the legitimate business site is accessible without completely disabling the URL Filtering inline ML feature, which would reduce overall security effectiveness.

When configuring the NGFW to act as a decryption broker for multiple transparent bridge security chains, the following items are required:

A unique Transparent Bridge Decryption Forwarding Profile to a single Decryption policy rule (B): Each decryption policy rule must be associated with a unique Transparent Bridge Decryption Forwarding Profile. This ensures that decrypted traffic is forwarded appropriately to the specific security chain.

A unique Decryption policy rule is required per security chain (C): You need to create a separate decryption policy rule for each security chain. This allows you to distribute the decrypted traffic among multiple security chains based on policy criteria.

These configurations enable the firewall to effectively manage and distribute the load across multiple security chains, ensuring optimal performance and security​ (Palo Alto Networks)​​ (Palo Alto Networks)

The Automated Correlation Engine in PAN-OS is designed to analyze firewall logs to detect and correlate actionable events on the network. This feature processes a series of related threat events to identify compromised hosts or other significant security issues. By automatically pinpointing areas of risk and providing detailed insights, it allows administrators to assess vulnerabilities and take preventive measures to protect network resources. This capability is crucial for optimizing security outcomes and maintaining a robust defense posture.

GlobalProtect is the Palo Alto Networks security component designed to extend next-generation firewall (NGFW) policies to remote users. It provides comprehensive security by ensuring that all network traffic from remote devices is inspected and secured, just as if the users were on the corporate network. This helps maintain consistent security policies and protections regardless of user location.
