About the Content Filtering Events Page

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

Use this page to view information about security events based on content filtering policies. The event viewer provides a view of all content filtering events and how the events are handled by content filter. This page can be used to view traffic on the network in real time or as a debugging tool to view how content filtering is operating.

Content filtering provides basic data loss prevention functionality. Content filtering screens traffic based on MIME type, file extension, protocol commands, and embedded object type. It either permits or blocks specific commands or extensions on a protocol-by-protocol basis.

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:

Summary View

The top of the page has a swim lane graph of all the content filtering events against the blocked events. You can use the widgets at the bottom of the page to view critical information such as top blocked protocol commands, top reasons, and top sources.

Table 25 describes the widgets on the Summary View page.

Table 25: Widgets on the Summary View Page



Top Blocked Protocol commands

Top Reasons

View the top reasons for blocking the content. For example: Inappropriate or harmful communication.

Top Sources

Detail View

You can aggregate the events using the Group By option. For example, you can group the events based on source country. The table includes information such as the event name, UTM category, source IP address, source country, and so on.
