It is not recommended to create more than 1000 rules of access to web resources, as this can cause the system to become unstable.
A web resource access rule is a set of filters and actions that Kaspersky Endpoint Security performs when the user visits web resources that are described in the rule during the time span that is indicated in the rule schedule. Filters allow you to precisely specify a pool of web resources to which access is controlled by the Web Control component.
The following filters are available:
Filter by content. Web Control categorizes web resources by content and data type. You can control user access to web resources with content and data falling into the types defined by these categories. When the users visit web resources that belong to the selected content category and / or data type category, Kaspersky Endpoint Security performs the action that is specified in the rule.
Filter by web resource addresses. You can control user access to all web resource addresses or to individual web resource addresses and / or groups of web resource addresses.
If filtering by content and filtering by web resource addresses are specified, and the specified web resource addresses and / or groups of web resource addresses belong to the selected content categories or data type categories, Kaspersky Endpoint Security does not control access to all web resources in the selected content categories and / or data type categories. Instead, the application controls access only to the specified web resource addresses and / or groups of web resource addresses.
Filter by names of users and user groups. You can specify the names of users and / or groups of users for which access to web resources is controlled according to the rule.
Rule schedule. You can specify the rule schedule. The rule schedule determines the time span during which Kaspersky Endpoint Security monitors access to web resources covered by the rule.
After Kaspersky Endpoint Security is installed, the list of rules of the Web Control component is not blank. Two rules are preset:
Scripts and Stylesheets rule, which grants all users access at all times to web resources whose addresses contain the names of files with the CSS, JS, or VBS extensions. For example: http://www.example.com/style.css, http://www.example.com/style.css?mode=normal.
Default rule. This rule is applied to any web resources that are not covered by other rules, and allows or blocks access to these web resources for all users.
