Discussion

Using trusted and recognized IOC sources may detect compromise and prevent systems from becoming compromised. An IOC stream is a series or stream of intel that is imported from a vendor based on a subscription service or manually downloaded and placed in a folder. Threat Response can be configured to retrieve the IOC content on a regularly scheduled basis. The items in an IOC stream can be manipulated separately after they are imported.

Check Content

Consult with the Tanium system administrator to determine if the Threat Response module is being used. If it is not, this is not applicable.

1. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web user interface (UI) and log on with multifactor authentication.

2. Click "Modules" on the top navigation banner.

3. Click "Threat Response".

4. Expand the left menu.

5. Click "Intel".

6. Select "Sources".

7. Verify all configured Threat Response Streams are configured to a documented trusted source.

If Threat Response is configured to a stream that has not been documented as trusted, this is a finding.
