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, which 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".
