Title

The Tanium Application Server console must be configured to initiate a session lock after a 15-minute period of inactivity. (Cat II impact)

Discussion

The Tanium Console, when CAC is enabled, will initiate a session lock based upon the ActivClient or other Smart Card software. By initiating the session lock, the console will be locked and not allow unauthorized access by anyone other than the original user. Although this setting does not apply when CAC is enabled, it should be explicitly disabled in the event CAC authentication is ever broken or removed.

Check Content

Using a web browser on a system that has connectivity to the Tanium Server, access the Tanium Server web user interface (UI) and log on with CAC. After logging in, click on "Preferences" in the top right corner of the UI. Verify the "Suspend console automatically if no activity detected for:" is configured to a value of "15" minutes or less. If the "Suspend console automatically if no activity detected for:" is not configured to a value of "15" minutes or less, this is a finding.
