SonicOS 7 Rules and Policies

Policy-based Application Rules

The SonicWall application signature databases are part of the application control feature, allowing very granular control over policy configuration and actions relating to them. These signature databases are used to protect users from application vulnerabilities as well as worms, Trojans, peer-to-peer transfers, spyware and backdoor exploits. The extensible signature language used in the SonicWall Reassembly-Free Deep Packet Inspection engine also provides proactive defense against newly discovered application and protocol vulnerabilities.

To create an App Rules policy

  1. Navigate to the OBJECT | Match Objects page.
  2. Click + Add. The Match Object Settings dialog opens.

  3. In the Match Object Settings dialog, create a match object of type Application List.

  4. Example Custom Match Object Targeting an Application shows a custom match object targeted at LimeWire and Kazaa Peer to Peer sharing applications.

    Example Custom Match Object Targeting an Application

    After creating an application-based match object, create a new App Rules policy of type App Control Content that uses the match object. Example: App Control Policy for Targeting Match Object shows a policy that uses the newly created “Kazaa/LimeWire P2P” match object to drop all Napster and LimeWire traffic.
