Title

The Tanium Module server must be installed on a separate system. (Cat II impact)

Discussion

Unauthorized access to the Tanium Server is protected by disabling the Module Server service on the Tanium Server and by configuring the Module Server on a separate system. When X509 smartcard certificates (CAC or PIV tokens) are used for access to the Tanium Server, the Tanium Module server must be on a separate system. In order to restrict access to the Tanium Server resulting from an attack on the Module Server, it is recommended that the Tanium Module Server be installed on a separate system or VM from the Tanium Server. Adding to this recommendation, if the Tanium Server is configured to accept X509 Smartcard certificates (also referred to as CAC or PIV tokens) in lieu of username/password logon, the requirement becomes explicit and the Tanium Module Server must be installed on a separate system or VM.
