Who added a new account ?
Sometimes is necessary to audit the configurations of the QRadar and find the people involved on the changes in the system. Those changes can be verified inside the “events” tab of QRadar (and filtering by the events from the QRadar device). Another quick way to find the audit information about the QRadar is checking it own logs. For example, to check the history of accounts added on the system, there is a quick command that you can execute to check who and when added new account. To get this information just execute the following command :
[root@MY_RADAR]# cat /var/log/audit/audit.log | grep ‘AccountAdded’ | less
You will get log lines such as the example below :
Jun 12 14:34:37 127.0.0.1 X&Y (7638) /console/JSON-RPC/QRadar.saveUser QRadar.saveUser | [Configuration] [UserAccount] [AccountAdded] ID: 24 | Username: ABC | Email: ABC@DEF | Description: | Role ID: 2 | Security Profile ID: 1
By analyzing the log line, we can verify that X&Y added new account ABC with the e-mail address of ABC@DEF at Jun the 12th at 14:43.
