Vulnerability discussion

Computer Groups allow a site running Tanium to assign responsibility of specific Computer Groups to specific Tanium console users. By doing so, a desktop administrator, for example, will not have the ability to enforce an action against a high visibility server.For large sites, it is crucial to have the Computer Groups and while a smaller site might not seem to require Computer Groups, creating them provides for a cleaner implementation. All sites will be required to have some kind of Computer Groups configured other than the default "All Computers".

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 "Administration". Select the "Computer Groups" tab. Under the "Name" column, verify specific groups exist other than the default "All Computers" and "No Computers". If site or organization specific computer groups do not exist, this is a finding.

Fix text

Using a web browser on a system that has connectivity to Tanium, access the Tanium web UI and log on with CAC. Click on the navigation button (hamburger menu) on the top left of the console and then click on "Administration". Select the "Computer Groups" tab. Configure specific Computer Groups in order to facilitate the management of computers by authorized individuals for those computers. Note: Tanium offer two ways to define computer groups. Refer to documentation for explanation found here: https://docs.tanium.com/platform_user/platform_user/console_computer_groups.html#Computer_Group_types Note: Active Directory Computer Groups may also be used to sync with Tanium Computer Groups as a means to satisfy this requirement.

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.
