AsyncOS periodically queries the update servers for new updates to all security service components, 
including the AVC engine. AVC engine updates can include support for new application types and 
applications, as well as updated support for existing applications if any application behaviors change. 
By updating the AVC engine between AsyncOS version updates, the Web Security appliance remains 
flexible without requiring a server upgrade.

AsyncOS for Web assigns the following default actions for the Global Access Policy:

New Application Types default to Monitor.

New application behaviors, such as block file transfer within a particular application; defaults 
to Monitor.

New applications for an existing application type default to the Application Type’s default.

In the Global Access Policy, you can set the default action for each Application Type, so new 
applications introduced in an AVC engine update automatically inherit the specified default action. See
