Description

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.

Access the Tanium Server console via a web browser. 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 DOD CA-##. On Certification “Path” tab, validate the path top-level is DoD Root CA 2. If the certificate authority is not DoD Root, this is a finding.
