Antivirus updates are released every 24 hours
and include: WildFire signatures for newly-discovered malware.
To get these updates every five minutes instead of once daily, you’ll
need a WildFire subscription. (Requires Threat Prevention) Automatically-generated command-and-control
(C2) signatures that detect certain patterns in C2 traffic. These
signatures enable the firewall to detect C2 activity even when the
C2 host is unknown or changes rapidly. (Requires Threat Prevention) New and updated list entries for built-in
external dynamic lists. These lists include malicious, high-risk,
and bulletproof host-provided IP addresses, and can help to protect
you against malicious hosts. (Requires Threat Prevention) Updates to the local set of DNS
signatures that the firewall uses to identify known malicious domains.
If you’ve set up DNS sinkholing, the firewall
can identify hosts on your network that try to connect to these
domains. To allow the firewall to check domains against the complete
database of DNS signatures, set up DNS Security.
