Title

The Tanium enterprise audit log reduction option must be configured to provide alerts based off Tanium audit data. (Cat II impact)

Discussion

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

Check Content

Using a web browser on a system that has connectivity to the Tanium Application, access the Tanium Application web user interface (UI). Log on with CAC. Click on the navigation button (hamburger menu) on the top left of the console. Click on "Connect". Review the configured Tanium Sources listed. If an "Audit Log" source does not exist, this is a finding. Select the "Audit Log" source. Select the audit connection found in the lower half of the screen. Verify the "Destination Type" is a SIEM tool. If the "Destination Type" is not a SIEM tool, this is a finding.
