Screen Events and Logs Overview
You can use the Screen Events page to view the information about security events based on screen profiles. Analyzing screen logs yields information such as attack name, action taken, source of an attack, and destination of an attack.
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.
By default, you can view data for all the devices. To view data for a specific device, click on the link beside Devices and select a device.
There are two ways to view your data. You can select either the summary view or the detail view.
Screen Events—Summary View
Click Summary View for a brief summary of all Screen events in your network. The data presented in the area graph is refreshed automatically based on the selected time range.
You can use widgets to view critical information such as top sources, top destinations, top source countries, and top destination countries. See Table 1 for descriptions of the widgets in this view.
Table 1: Screen Events Summary View Widgets
Widget | Description |
|---|---|
Top Sources | Top source IP addresses of the network traffic; sorted by the number of event occurrences. |
Top Destinations | Top destination IP addresses of the network traffic; sorted by the number of event occurrences. |
Top Source Countries | Top source countries from where the event source originated; sorted by the number of IP addresses. |
Top Destination Countries | Top destination countries targeted for the attack; sorted by the number of destination IP addresses. |
Screen Events—Detail View
Click Detail View for comprehensive details of all screen events in a tabular format that includes sortable columns. You can sort the events using the Group by option. For example, you can sort the events based on threat severity. The table includes information such as the event name, source country, source IP, destination country, attack name, and so on.
The Legacy Node option is displayed in the event viewer after the legacy log collector node is added on the Logging Nodes page. We’ve added the legacy log collector support only for read only purpose to view existing log collector data. New logs should point to Security Director Insights VM as the log collector. Select the Legacy Node checkbox to view the existing log collector data. When you clear the Legacy Node checkbox, Security Director Insights log collector data is displayed.
