Ensure DNS sinkholing is configured on all anti-spyware profiles in use
Descrição
Configure DNS sinkholing for all anti-spyware profiles in use. All internal requests to the selected sinkhole IP address must traverse the firewall. Any device attempting to communicate with the DNS sinkhole IP address should be considered infected. PASS requires default-paloalto-dns with action sinkhole in an anti-spyware profile; confirm every profile in use and the sinkhole IPv4/IPv6 addresses. Audited against the PAN-OS running configuration in set format: run 'set cli config-output-format set', then 'configure' and 'show' (or 'show config running') and save the full output.

This should be set to sinkhole.paloaltnetworks.com, or if an internal host is set then that host IP or FQDN should be in that field Verify the 'Sinkhole IPv6' IP address is correct. This should be set to IPv6 Loopback IP (::1), or if an internal DNS Sinkhole host is set then that host IP or FQDN should be in that field Navigate to Policies > Security Policies For each outbound security Policy, in the Actions tab, set the Anti-Spyware setting to include the Spyware Profile created, either explicitly or as a Group Profile
