Access Control Rule Trust Action

The Trust action allows traffic to pass without deep inspection or network discovery. Trusted traffic is still subject to identity requirements and rate limiting.

Diagram showing that the Trust rule action allows traffic to pass and you cannot further inspect the traffic with a file, intrusion, or network discovery policy.

Note

Some protocols, such as FTP and SIP, use secondary channels, which the system opens through the process of inspection. In some cases, trusted traffic can bypass all inspection, and these secondary channels cannot be opened properly. If you run into this problem, change the trust rule to Allow.
For an access control policy with rule action as Trust and logging options disabled, you will observe that the end-of-flow events are still generated in the system. The events are not visible on the management center event pages.
