DESCRIPTION:

This is a scenario based article of the SonicWall App Control Advanced feature. In this scenario we describe how to block the App Control Advanced Category - IM for all users except one user group and to allow Yahoo! Messenger, Skype, Trillian and Windows Live Messenger for selected users.

The following application needs to be blocked / allowed for the following users:

 Managers would be allowed all IM applications. All IM applications other than the above would be blocked for the rest.

RESOLUTION:

Create User Groups

• Login to the SonicWall management interface. 
• Navigate to Manage at the top of the page.
• Navigate to the Users | Local users & Groups page.
• Select the Local Groups tab.
• Create the following user groups.
  • Managers
  • Accounts
  • Marketing
    

Configure Authentication

• In order for the SonicWall to enforce Application Control based on users/groups, we need to enable authentication on the SonicWall. Authentication can be either explicit, using Policies | Rules | Access Rules, or implicit, using Single Sign-on. In this example we create the following LAN | WAN rule to force authentication.

Configure App Control Advanced - IM Category

• Check the box under Enable App Control and click on Accept at the top of the page.

• Select Enable under Log.
• Select All under Included Users/Groups.
• Select the user group Managers under Excluded Users/Groups.
• Click OK .
  
• With this, all users or groups would be blocked from IM applications except the user group Managers. Now we configure individual applications to allow specific user groups.
