Security Intelligence Categories

Security Intelligence categories are determined by the system-provided feeds described in Security Intelligence.

These categories are used in the following locations:

  • The Networks sub-tab on the Security Intelligence tab of an access control policy

  • The URLs sub-tab beside the Networks tab on the Security Intelligence tab of an access control policy

  • In a DNS policy on the DNS tab in the DNS rule configuration page

  • In events generated when traffic matches Block or Monitor configurations in the above locations

Note

If your organization is using Secure Firewall threat intelligence director: When viewing events, you may see categories that indicate that the action was taken by TID, such as TID URL Block.

Categories are updated by Talos from the cloud, and this list may change independently of Firepower releases.
