About the Web Filtering Events Page

To access this page, click Monitor > Logs > 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.

Note:

You can only recategorize the Juniper NextGen URL categories. To recategorize the URL, right-click on the URL or click More and select Request URL Categorization. The Request URL Categorization page opens. For more information on the URL recategorization, see Request URL Recategorization.

The following examples indicate the types of logs that the Web Filtering Events page displays: WEBFILTER_URL_BLOCKED and all WEB filter related events

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.

Note:

This information is sourced from Web filtering in content security.

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 an area graph of all the Web filtering events against the blocked events. Below the area graph 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.
