The Tanium documentation identifying recognized and trusted IOC Detect streams must be maintained.

An IOC stream is a series or "stream" of IOCs that are imported from a vendor based on a subscription service. An IOC stream can be downloaded manually or on a scheduled basis. The items in an IOC stream can be separately manipulated after they are imported.

Consult with the Tanium System Administrator to determine if the "Tanium Detect" module is being used. If it is not, this is "Not Applicable".

Review the documented list of IOC trusted stream sources.

If the site does use an external source for IOCs and the IOC trusted stream source is not documented, this is a finding.

Consult with the Tanium System Administrator to determine if the "Tanium Detect" module is being used. If it is not, this is "Not Applicable".

Prepare and maintain documentation identifying the Tanium IOC trusted stream sources.
