About the Web Filtering Events Page

To access this page, click Monitor > Security Events > Web Filtering.

Use the Web Filtering page to view information about security events based on Web filtering policies. Web filtering allows you to permit or block access to specific websites by URL or by URL category using cloud-based lookups, a local database, or an external Websense server. Analyzing Web filtering logs yields useful security management information such as users detected accessing restricted URLs and actions taken by the system. Using the time-range slider, you can quickly focus on the area of activity that you are most interested in. Once the time range is selected, all of the data presented in your view is refreshed automatically. You can also use the Custom button to set a custom time range.

There are two ways to view your data. You can select either the Summary View tab or the Detail View tab.

Tasks You Can Perform

You can perform the following tasks from this page:

  • View a brief summary of all the Web filtering events in your network. See Summary View.

  • View the comprehensive details of events in a tabular format that includes sortable columns. See Detail View.

Summary View

The top of the page has a swim lane graph of all the Web filtering events against the blocked events.

Below the swim lanes are widgets displaying critical information such as top sources, top destinations, top users, and top reporting devices.

You can use the widgets at the bottom of the page to view critical information such as top URLs blocked, top matched profiles, top sources, and top destinations.

Table 1 describes the widgets on the Summary View page.
