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.

Using a web browser on a system that has connectivity to Tanium, access the Tanium web user interface (UI) and 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.
