Title

Tanium Comply must be configured to receive SCAP feeds only from trusted sources. (Cat II impact)

Discussion

NIST-validated SCAP XML documents are provided from several possible sources such as DISA, NIST, and the other non-government entities. These documents are used as the basis of compliance definitions leveraged to automate compliance auditing of systems. These documents are updated on different frequencies and must be manually downloaded on regular intervals and imported in order to be current. Non-approved SCAP definitions lead to a false sense of security when evaluating an enterprise environment.

Check Content

Using a web browser on a system that has connectivity to Tanium, access the Tanium web user interface (UI) and log on with CAC. Click on the navigation button (hamburger menu) on the top left of the console. Click on "Comply". Along the left side of the interface, click on "Benchmarks" then "Configuration Compliance". Verify all imported compliance benchmarks are from a documented trusted source. If any compliance benchmark is found that does not come from a documented trusted source, this is a finding.
