Configure DNS Security Over TLS (NGFW (Managed by PAN-OS or Panorama))

1. Log in to the NGFW.
2. Enable DNS Security is configured to inspect DNS requests. You can use your existing security profile if you want to use the same DNS Policies settings for DNS Security over TLS traffic.
3. Create a decryption policy rule (similar to the example below) with an action to decrypt HTTPS traffic on port 853, which includes DNS Security over TLS traffic (refer to the Decryption Best Practices for more information). When DNS Security over TLS traffic is decrypted, the resulting DNS requests in the logs appear as conventional dns-base applications.
4. (Optional) Search for activity on the firewall for decrypted TLS-encrypted DNS queries that have been processed using DNS Security.

   1. Select MonitorLogsTraffic and filter based on the application using dns-base and port 853 (which is exclusively used for DNS Security over TLS transactions), for example, ( app eq dns-base ) and ( port.src eq 853 ).
   2. Select a log entry to view the details of a detected DNS threat.
   3. The Application should display dns-base in the General pane and the Port in the Source pane of the detailed log view. Other relevant details about the threat are displayed in their corresponding windows.
