Media type filtering ensures that the users of your network can only access media belonging to types that are allowed under your web security policy. For example, access to streaming media might not be allowed because it consumes too many resources.
A default process for media type filtering is implemented on Web Gateway after the initial setup. This process includes the following important configuration item:
- Media Type Filtering rule set — Default rule set for media type filtering
The default process requires that you maintain lists of media types, which are used by the rules in the rule set for allowing and blocking access to particular media types.
You can further modify this process to meet the requirements of your organization. You can also extend the process in several ways or set up your own process.
