Vulnerability discussion

The Tanium Console, when CAC is enabled, will initiate a session lock based upon the ActivClient or other Smart Card software.By initiating the session lock, the console will be locked and not allow unauthorized access by anyone other than the original user.Although this setting does not apply when CAC is enabled, it should be explicitly disabled in the event CAC authentication is ever broken or removed.

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. After logging on, in the top right corner of the UI select the drop-down arrow and click on "Preferences". Verify the "Suspend console automatically if no activity detected for:" is configured to a value of "15" minutes or less. If the "Suspend console automatically if no activity detected for:" is not configured to a value of "15" minutes or less, this is a finding.

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.
