Fix Recommendation

1. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web UI and log on with multifactor authentication.

2. Click "Modules" on the top navigation banner.

3. Click "Interact".

4. Within "Interact", under "Explore Data", ask the question "Get Tanium Client Directory Permissions from all machines".

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

5. Click the "Not Restricted" row.

6. 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.

7. Choose a schedule to deploy the hardening.

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

9. Click "Deploy Action".

10. Verify settings.

11. Click "Show Client Status Details".
