About the Firewall Events Page

 

To access this page, click Monitor > Security Events > Firewall.

Use the Firewall Events page to view information about security events based on firewall policies. Analyzing firewall logs yields useful security management information, such as attempts to breach your network and observing the inherent characteristics of your traffic in real-time. 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 firewall 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 data presented in the line graph (also known as swim lanes) is refreshed automatically based on the selected time range. The line graph shows light blue lanes that represent all firewall events and dark blue lanes represent blocked firewall events.

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

Table 1 describes the widgets on the Summary View page.
