Description
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 redeploy 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.

1. Using a web browser on a system that has connectivity to the Tanium Application, access the Tanium Application web user interface (UI) and log on with multi-factor authentication. 2. Click "Administration" on the top navigation banner. 3. Under Actions, select "Scheduled Actions". 4. Look for a scheduled action titled "Client Service Hardening - Hide Client from Add-Remove Programs". 5. If a scheduled action titled "Client Service Hardening - Hide Client from Add-Remove Programs" does not exist, this is a finding. If the scheduled action exists, select it and if it is not approved (the "Approve" button at the top of the section will be displayed if not approved), this is a finding. If the scheduled action exists and has been approved but does not disable the visibility of the client in Add-Remove Programs, this is a finding. If the action is not configured to repeat at least every hour, this is a finding. If the scheduled action is not targeted at an "All Computers" Action Group, this is a finding.
