Title

Computer Groups must be used to restrict console users from affecting changes to unauthorized computers. (Cat II impact)

Discussion

Computer Groups allow a site running Tanium to assign responsibility of specific Computer Groups to specific Tanium console users. By doing so, a desktop administrator, for example, will not have the ability to enforce an action against a high visibility server. For large sites, it is crucial to have the Computer Groups and while a smaller site might not seem to require Computer Groups, creating them provides for a cleaner implementation. All sites will be required to have some kind of Computer Groups configured other than the default "All Computers".

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. Click on "Administration". Select the "Computer Groups" tab. Under the "Group Name" column, verify specific groups exist other than the default "All Computers" and "No Computers". If site or organization specific computer groups do not exist, this is a finding.

Fix Text

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. Click on "Administration". Select the "Computer Groups" tab. Configure specific Computer Groups in order to facilitate the management of computers by authorized individuals for those computers. Note: Active Directory Computer Groups may also be used to sync with Tanium Computer Groups as a means to satisfy this requirement.
