Which of the following allows the firewall or Panorama to tag a policy object when it receives a log that matches specific criteria?

The concept of auto-tagging is fundamental in the context of security management, particularly when it comes to firewall policies. Auto-tagging allows a firewall or management tool like Panorama to automatically assign tags to policy objects based on predefined criteria derived from log data. This feature enhances the organization and management of policies by enabling automated categorization, which supports better visibility and compliance.

When log entries match specific criteria, auto-tagging helps in dynamically updating the associated policy objects with relevant tags without requiring manual intervention. This capability is particularly useful for adapting to changing network conditions, threats, or compliance requirements, allowing administrators to maintain an agile and effective security posture.

The other options do not fundamentally address the functionality of tagging policies based on log data. While DAG (Data Access Gateway) relates to data management, Zero Trust is a security model that emphasizes strict access controls, and Universal policy refers to configurations that can be applied across different devices and environments but doesn't inherently include the auto-tagging functionality described in the question. Therefore, auto-tagging stands out as the correct answer because it directly describes the ability of a firewall or Panorama to tag objects based on log matches automatically.
