How to Block Toolbar Search using App Rules (Application Firewall) and Client DPI-SSL
Resolution
Enabling Client DPI-SSL
Note: Before enabling Client DPI-SSL, administrators must be aware that Client DPI-SSL will proxy all outgoing SSL connections. To this end, SonicWall will re-sign the SSL certificates passing to hosts. This will trigger certificate errors in the browsers. To avoid these errors, import the SonicWall DPI-SSL CA certificate as a trusted Root CA into the browser's (or the computer's) certificate store. For more information, see UTM: Distributing the Default SonicWall DPI-SSL CA certificate to client computers using Group Policy
1. Navigate to the DPI-SSL | Client SSL page.
2. Enable check box Enable SSL Client Inspection
3. Enable check box Application Firewall
4. Click on Accept at the top to save the changes.
Create a Match Object of type HTTP URI Content
1. Click on Add New Match Object to open the Add/Edit Match Object window.
2. Enter a name for the match object.
