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 "Set Client Directory Permissions".

The results will show a "Count" of clients' compliant and non-compliant hardening for the "Tanium Client Directory Permissions".

Non-compliant clients will have a count other than "0" for "Not Restricted" or "Error: No Permissions".

Select each of the "Not Restricted" or "Error: No Permissions" statuses.

Select "Deploy Action".

In the "Deploy Action" dialog box change the package to "Client Service Hardening - Set SYSTEM only permissions on the Tanium Client directory" as the package.

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 in the bottom.

Click on "Deploy Action".

Verify settings.

Click on "Show Client Status Details".
