Fix Recommendation

1. Using a web browser on a system that has connectivity to the Tanium Application, access the Tanium Application web user interface (UI) and log on with multi-factor authentication.

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

3. Under Permissions, select "Users".

4. Analyze the users configured in the Tanium interface.

5. Determine least privileged access required for each user to perform their respective duties.

6. Move users to the appropriate LDAP security group to ensure the user is synced to the appropriate Tanium User Role.

7. If the appropriate LDAP security groups are not already configured, create the groups and add the appropriate users.

8. Ensure LDAP sync repopulates the Tanium Users' associated Roles accordingly.

Check Contents

1. Consult with the Tanium System Administrator to review the documented list of Tanium users.

2. Review the users' respective approved roles, as well as the correlated LDAP security group for the User Roles.

3. Validate LDAP security groups/Tanium roles are documented to assign least privileged access to the functions of the Tanium Server through the Tanium interface.

If the documentation does not reflect a granular, least privileged access approach to the LDAP Groups/Tanium Roles assignment, this is a finding.
