Configuring category-based web control

To add or modify a Traffic Security category-based rule:

1. Open the Web Control rules window.
2. Open the Categorization tab.
3. Select the Apply rules for web traffic category control check box.
   

   If the check box is selected, Kaspersky Security for Windows Server categorizes and blocks web resources, that fall under the selected categories.

   If the check box is cleared, Kaspersky Security for Windows Server does not perform categorization.

   The check box is cleared by default.

   Category control settings become available.

4. Select or clear the following check boxes:
   • Allow access if the web page can not be categorized.
   • Allow access to legitimate web resources that can be used to damage your device.
   • Allow access to legitimate advertisement.
5. In the list of available categories:
   • Select the corresponding check box to allow a category.

     The Type column changes to Allowing.

   • Clear the corresponding check box to block a category.

     The Type column changes to Denying.

   The list of categories is predefined and cannot be modified (you cannot add or remove categories).

6. Click Save.

The rule configuration is saved.

Using the not-a-virus mask

To use the not-a-virus mask for category analysis:

1. In the Application Console tree, open the KSN Usage task settings.
2. Select the Send data about scanned URLs check box.
3. Start the KSN Usage task.
4. In the Traffic Security settings window, select the Use KSN for protection check box.
5. In the Web Control rules window, on the Categorization tab, select the Apply rules for web traffic category control check box.
6. In the list of categories, select the categories for which you want to apply the not-a-virus mask.

   The Traffic Security task will not detect objects corresponding to the mask in the selected categories.
