Vulnerability 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

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.

Fix text

Request or regenerate the certificate from a DoD Certificate Authority.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
