Discussion

System access should be reviewed periodically to verify that all Tanium users are assigned the appropriate role, with the least privileged access possible to perform assigned tasks being the recommended best practice. Users who have been removed from the documentation should no longer be configured as a Tanium Console User. Consider removing users that have not logged onto the system within a predetermined time frame. When using Active Directory synchronization, as is required by this STIG, User Roles assignments are via the AD Sync connector. AD security groups correlate, one to one, to Tanium User Roles. To change a Tanium user's User Role, their Active Directory account needs to be moved to the AD security group that correlates with the applicable User Role.

Check Content

Using a web browser on a system that has connectivity to Tanium, access the Tanium web user interface (UI) and log on with CAC.

Click on the navigation button (hamburger menu) on the top left of the console.

Click on "Administration".

Select the "Users" tab.

Verify each user against the Tanium approved users list, and review the assigned roles for each user against the "User Role" column.

If any user exists in Tanium but is not on the Tanium-approved users list and/or if any user exists in Tanium at a more elevated User Role than that documented on the list, this is a finding.
