Monitoring Antivirus Events

Purpose

Use this page to view information about security events based on antivirus policies. The event viewer provides a view of all antivirus events and the action taken by the virus scanner.

The antivirus scanner inspects files transmitted over several protocols to determine if the files exchanged are malicious (for example, viruses, Trojans, rootkits, and worms).

Action

To monitor events select Monitor>Events>Antivirus in the J-Web user interface.

Meaning

Time Range graph displays the trend of all events or flow for all the events that has transpired in the device.

You can specify the duration of time for which you want to view the trend for all events. The available options are 30m, 1h, 2h,…, and so on, which are displayed at the top right hand side of the page. For example, if you choose 30m, the end time is the current system time and the start time is the preceding 30 minutes from the current system time.

Click Custom to specify a customized time range. The Custom Time Range Selection popup window is presented. You can set the from and to date and time, and click OK to set the time range.

To refresh the graph on demand, click the refresh button.

You can also drag the slider in the Time Range graph from the extreme left or right of the graph and set the time range to see the trend or flow of events that has transpired in that time range.

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

The Summary View is selected by default, and it gives a brief summary of all the antivirus events in your network.

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 antivirus events.

Below the swim lanes are widgets displaying critical information such as top five sources and top five destinations.

See Table 26 for descriptions of the widgets.

Table 26: Widgets in Summary View

Widget Name

Displays

Top Sources

Top five source IP addresses of the network traffic; sorted by event count.

Top Destinations

Top five destination IP addresses of the network traffic; sorted by event count.

Click the Detailed View for comprehensive details of events in a grid format that includes sortable columns. It displays information in grids that are lazy loaded with infinite scrolling. You can narrow down your search to a particular event based on Event-Name, Source-Address, or Destination-Address. The table includes information such as the rule that caused the event, severity for the event, event ID, traffic information, and how and when the event was detected.

Table 27: Filter Options in Detailed View

The dropdown filter that is displayed above the grids.

Options available in the filter dropdown are: Event-Name, Source-Address, Destination-Address, Source-Name, User, Role, Reason, Profile, Protocol, and Category.

Select the criteria or parameter on which you want to construct the filter statement.

Text box

Displays the filter parameter that you selected from the filter dropdown.

Note:

In the filter statement the following limitation exists.

  • You can use only one operator at a time.
  • You can use only one instance of the criteria or paramenter in one filter statement.

For example, if you have used & operator and the parameter Event-Name once, I cannot use them again in the same filter statement

CORRECT USAGE: Event-Name = rt_flow_session_close & application=TELNET

WRONG USAGE:event name = rt_flow_session_close & event-name = rt_flow_session_create

WRONG USAGE:event name = rt_flow_session_close & source-address = x.x.x.x & application = TELNET

Note: The filter statement is NOT case-sensitive.

Add the parameter for which you want to filter. For example, in the dropdown filter if you selected event-name as the parameter, the text box displays Event-Name =. If you add AV_VIRUS_DETECTED_MT to see only antivirus events then the text box displays Event-Name = AV_VIRUS_DETECTED_MT.
