Using a web browser on a system that has connectivity to Tanium, access the Tanium web UI and log on with CAC.

On the Dashboard, select "Client Service Hardening".

Select the "Set Client Directory Permissions".

Tanium will parse the script and return a row for "Restricted" and a row for "Not Restricted", with their respective client counts.

Click on the "Not Restricted" row.

Select "Deploy Action".

In the "Deploy Action" dialog box, the package "Client Service Hardening - Set SYSTEM only permissions on Tanium Client directory" will be selected.

The clients that have their Tanium Client directory "Not Restricted" will be displayed in the bottom window.

Choose a schedule to deploy the hardening.

Under "Targeting Criteria", in the Action Group select "All Computers" from the drop-down.

Click on "Deploy Action".

Verify settings.
