Allows you to schedule the frequency for
retrieving updates. You can define how often and when the
dynamic content updates occur—the Recurrence and time—and
whether to Download Only or to Download
and Install scheduled updates For Antivirus and
Applications and Threats updates, you have the option to set a minimum
Threshold of time that a content update must be available before
the firewall installs it. Very rarely, there can be an error in
a content update and this threshold ensures that the firewall only
downloads content releases that have been available and functioning
in customer environments for the specified amount of time. For
Applications and Threats content updates, you can also set a threshold
that applies specifically to content updates with new and modified
applications. An extended application threshold gives you more time
to assess and adjust your security policy based on changes that
new or modified applications introduce. For WildFire updates,
you have the option to retrieve signatures in real-time, allowing
you to access the signatures as soon as they are generated. Signatures
that are downloaded during a sample check are saved in the firewall
cache, and are available for fast (local) look-ups. In addition,
to maximize coverage, the firewall also automatically downloads
an additional signature package on a regular basis when real-time
signatures is enabled. These supplemental signatures are added to
the firewall cache and remain available until they become stale
and are refreshed or are overwritten by new signatures. |
