Rules and Policies > App Rules

You must enable application control before you can use App Rules policies, although you can create policies without enabling the feature. Application control is enabled with a global setting, and must also be enabled on each network zone that you want to control.

For any of the listed access rules, when the Enabled checkbox is selected from the POLICY | Rules and Policies > Access Rules page, then the dpi=1 Syslog tag is seen in Connection Closed Syslog messages for all traffic that passed through Deep Packet Inspection. Traffic that did not pass through DPI shows dpi=0 in the Connection Closed Syslog messages. For more information about the Index of Syslog Tags Field Descriptions and Syslog examples showing the SPI tag, see the SonicOS Log Events Administration Guide.

You can configure application control policies by using the App Rule wizard or manually on the POLICY | Rules and Policies > App Rules page. The wizard provides a safe method of configuration and helps prevent errors that could result in unnecessary blocking of network traffic. Manual configuration offers more flexibility for situations that require custom actions or policies.

App Rules policies require a match object (or application list object) and an action object. You can configure match objects on the OBJECT | Match Objects > Match Objects pages. You also configure application list objects on the OBJECT | Match Objects > Match Objectspages. When creating an application list object, you choose from the same application categories, signatures, or specific applications that are shown on the POLICY | Security Services > App Control page. Action objects are created on the OBJECT | Action Objects pages.

By comparison, you can configure application control global blocking or logging settings on the POLICY | Rules and Policies > App Control > App Rule Actions page. No match objects or action objects are required.

For information about configuring App Rules policies and the objects used in them, see the following topics:
