The reliability of the Tanium client's ability to operate depends upon controlling access to the Tanium client service. By restricting access to SYSTEM access only, the non-Tanium system administrator will not have the ability to impact operability of the service.
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 - Allow Only Local SYSTEM to Control Service". If a scheduled action titled "Client Service Hardening - Allow Only Local SYSTEM to Control Service" does not exist, this is a finding. 5. 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 restrict control of the Tanium Client service to "Allow Only Local SYSTEM to Control Service," 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.
