Security Profile: DNS Security (PAN-OS & Panorama)

1. To take advantage of DNS Security, you must have an active DNS Security and Threat Prevention (or Advanced Threat Prevention) subscription.

   Verify that you have the necessary subscriptions. To verify which subscriptions that you currently have licenses for, select DeviceLicenses and verify that the appropriate licenses display and have not expired.
2. Verify that the paloalto-dns-security App-ID in your security policy is configured to enable traffic from the DNS security cloud security service.

   If your firewall deployment routes your management traffic though an Internet-facing perimeter firewall configured to enforce App-ID security policies, you must allow the App-IDs on the perimeter firewall; failure to do so will prevent DNS security connectivity.
3. Configure DNS Security signature policy settings to send malicious DNS queries to the defined sinkhole.

   If you use an external dynamic list as a domain allow list, it does not have precedence over the DNS Security domain policy actions. As a result, when there is a domain match to an entry in the EDL and a DNS Security domain category, the action specified under DNS Security is still applied, even when the EDL is explicitly configured with an action of Allow. If you want to add DNS domain exceptions, either configure an EDL with an Alert action or add them to the DNS Domain/FQDN Allow List located in the DNS Exceptions tab.
4. Attach the Anti-Spyware profile to a Security policy rule.
5. Test that the policy action is enforced.
