Vulnerability discussion

An IOC stream is a series or “stream” of IOCs that are imported from a vendor based on a subscription service or manually downloaded and placed in a folder. IOC Detect can be configured to retrieve the manually pulled IOC content on a regularly scheduled basis. The items in an IOC stream can be separately manipulated after they are imported.

Check content

Using a web browser on a system that has connectivity to the Tanium Server, access the Tanium Server web user interface (UI) and log on with CAC. Click on "IOC Detect". Along the right column of the interface, click on the icon with the down arrow. Verify all configured IOC Detect Streams are configured to a documented trusted source. If any configured IOC Detect Stream is configured to a stream which has not been documented as trusted, this is a finding.

Fix text

Using a web browser on a system that has connectivity to the Tanium Server, access the Tanium Server web user interface (UI) and log on with CAC. Click on "IOC Detect". Along the right column of the interface, click on the icon with the down arrow. Delete IOC streams which are configured to non-trusted source, or re-configured to point to a trusted source.

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.
