Enable Local Signature and URL Category Generation
The WildFire appliance can generate signatures
locally based on the samples received from connected firewalls and
the WildFire API, as an alternative to sending malware to the public
cloud for signature generation. The appliance can generate the following
types of signatures for the firewalls to use to block malware and
any associated command and control traffic:
—Detect and block malicious files. WildFire adds these
signatures to WildFire and Antivirus content updates.
—Detect and block callback domains for command
and control traffic associated with malware. WildFire adds these signatures
to WildFire and Antivirus content updates.
—Categorizes callback domains as malware
and updates the URL category in PAN-DB.
the firewalls to retrieve the signatures generated by the WildFire appliance
as frequently as every five minutes. You can also send the malware
sample to the WildFire public cloud, in order to enable the signature
to be distributed globally through Palo Alto Networks content releases.
This allows the WildFire appliance to receive the latest
threat intelligence from Palo Alto Networks.

It is a best practice to configure
your firewalls to retrieve content updates from both the WildFire
public cloud and WildFire appliance. This ensures that your firewalls
receive signatures based on threats detected worldwide, in addition
to the signatures generated by the local appliance.
