Ensure DNS sinkholing is configured on all anti-spyware profiles in use
Beschreibung
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.
