See How New and Modified App-IDs Impact Your Security Policy
Newly-categorized and modified App-IDs can change
the way the firewall enforces traffic. Perform a content update
policy review to see how new and modified App-IDs impact your security
policy, and to easily make any necessary adjustments. You can perform
a content update policy review for both downloaded and installed
content.
For a downloaded or currently installed content release,
click Review Policies in the Action column. The Policy
review based on candidate configuration dialog allows
you to filter by Content Version and view
either new or modified App-IDs introduced in a specific release
(you can also filter the policy impact of new App-IDs according
to Rulebase, Virtual System,
and Application).
Select an App-ID from the Application drop-down
to view policy rules that currently enforce the application. The
rules displayed are based on the App-IDs that match to the application
before the new App-ID is installed (view application details to
see the list of application signatures that an application was Previously
Identified As before the new App-ID).
Use the detail provided in the policy review to plan
policy rule updates to take effect when the App-ID is installed,
or if the content release version that included the App-ID is currently
installed, the changes you make take effect immediately.
You can Add app to selected policies or Remove
app from selected policies.
