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 IOC content on a regularly scheduled basis. The items in an IOC stream can be separately manipulated after they are imported.

Check content

Consult with the Tanium System Administrator to determine if the Tanium Detect module is being used. If it is not, this finding is "Not Applicable". If it is being used, determine where the IOC stream comes from. Access the Tanium Module Server interactively. Log on with an account with administrative privileges to the server. Open an Explorer window. If the folder hosting the IOC Detect Folder streams is not mapped to the Tanium Module Server, temporarily map it to the Tanium Module Server. Right-click on the folder and choose "Properties". Select the "Security" tab. Click on the "Advanced" button. If the accounts listed in the "Security" tab do not match the list of accounts found in the Tanium documentation, this is a finding. If the folder was temporarily mapped to the Tanium Module Server, remove the folder mapping.

Fix text

Consult with the Tanium System Administrator to determine if the "Detect" module is being used. If it is not, this is "Not Applicable". Access the Tanium Module Server interactively. Log on with an account with administrative privileges to the server. Open an Explorer window. If the folder hosting the IOC Detect Folder streams is not mapped to the Tanium Module Server, temporarily map it to the Tanium Module Server. Right-click on the folder and choose "Properties". Select the "Security" tab. Click on the "Advanced" button. If the accounts listed in the "Security" tab do not match the list of accounts, with the exception of SYSTEM, remove the additionally listed accounts. If the accounts listed in the "Security" tab are missing accounts from the documentation, with the exception of SYSTEM, add the additionally listed accounts with a minimum of READ permissions. If the folder was temporarily mapped to the Tanium Module Server, remove the folder mapping.

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.
