Vulnerability 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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
