Title

The ability to uninstall the Tanium Client service must be disabled on all managed clients. (Cat II impact)

Discussion

By default, end users have the ability to uninstall software on their clients. In the event the Tanium Client software is uninstalled, the Tanium Server is unable to manage the client and must re-deploy to the client. Preventing the software from being displayed in the client's Add/Remove Programs will lessen the risk of the software being uninstalled by non-Tanium System Administrators.

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. From the Dashboard, under "Client Service Hardening", click on "Hide From Add-Remove Programs". The results will show a "Count" of clients matching the "Tanium Client Visible in Add-Remove Programs" query. If the "Count" shows any quantity other than zero, this is a finding.
