Title

The Tanium Server certificate must be signed by a DoD Certificate Authority. (Cat II impact)

Discussion

The Tanium Server has the option to use a "self-signed" certificate or a Trusted Certificate Authority signed certificate for SSL connections. During evaluations of Tanium in Lab settings, customers often conclude that a "self-signed" certificate is an acceptable risk. However, in production environments it is critical that a SSL certificate signed by a Trusted Certificate Authority be used on the Tanium Server in lieu of an untrusted and insecure "self-signed" certificate.

Check Content

Using a web browser on a system, which has connectivity to the Tanium Application, access the Tanium Application web user interface (UI). Log on with CAC. When connected, review the Certificate for the Tanium Server: In Internet Explorer, right-click on the page. Select "Properties". Click on the "Certificates" tab. On the "General" tab, validate the Certificate shows as issued by a DOD Root CA. On Certification "Path" tab, validate the path top-level is a DoD Root CA. If the certificate authority is not DoD Root CA, this is a finding.

Fix Text

Request or regenerate the certificate from a DoD Root Certificate Authority.
