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.
Using a web browser on a system that has connectivity to Tanium, access the Tanium web user interface (UI) and log on with CAC. Click on the navigation button (hamburger menu) on the top left of the console. Click on "Administration". Select the "Scheduled Actions" tab. 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. 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.
Using a web browser on a system that has connectivity to Tanium, access the Tanium web UI and log on with CAC. From the Dashboard, under "Client Service Hardening", click on "Control Service State Permissions". The results will show a "Count" of clients matching the "Service Control is set to default permissions" query. Select the result line for "Service Control is set to default permissions". Choose "Deploy Action". Deployment Package drop-down select "Client Service Hardening - Allow Only Local SYSTEM to Control Service". Configure the schedule to repeat at least every hour for the requested action. Under "Targeting Criteria", in the Action Group select "All Computers" from the drop-down. Click on "Show preview to continue". Non-compliant systems will be displayed at the bottom. Click on "Deploy Action". Verify settings. Click on "Show Client Status Details".
