Managing an IBM QRadar integration

You can take advantage of the rich data gathered by Change Auditor and use it with QRadar on-premises deployments. To begin sending event data, you need to create the QRadar extension and a QRadar event subscription with Change Auditor. The subscription contains information about where to send the notifications and heartbeats and the event subsystems to include.

Select Extensions Management | Add.
If prompted that the extension is not signed, select Install. When prompted to overwrite or keep existing data, select Overwrite.

Working with QRadar subscriptions through the client

From the Administration Tasks, select Configuration | Event Subscriptions.

Click Add QRadar Subscription to open the event subscription wizard.

Click Next to select the events to forward based on subsystem and event date. Once the subscription is created the starting event date and time cannot be changed.
By default, events start sending after the subscription is created. To change when to begin sending events, click Send events starting and select the desired date and time. The time cannot be more than 30 days prior to the Change Auditor 7.0 installation date.

Click Next to create the required extension to import to your QRadar instance. The extension instructs QRadar on how to read and present Change Auditor events. Specifically, it defines the log source (coordinator) and maps Change Auditor event columns to QRadar event columns.
NOTE: If you have previously configured your QRadar instance for Change Auditor, you can select My QRadar instance is already configured and click Finish to complete the subscription setup.

The Change Auditor extension must be added to QRadar for it to read and present Change Auditor events. Specifically, the extension defines the log source (coordinator) and maps Change Auditor event columns to QRadar event columns.

Use this command to create and generate a zip file that contains XML with the required extension. The extension must then be imported to QRadar.
