Title

Tanium endpoint files must be excluded from host-based intrusion prevention intervention. (Cat II impact)

Discussion

Similar to any other host-based applications, the Tanium Client is subject to the restrictions other system-level software may place on an operating environment. Antivirus, IPS, Encryption, or other security and management stack software may disallow the Tanium Server from working as expected. https://docs.tanium.com/client/client/requirements.html#Host_system_security_exceptions

Check Content

Consult with the Tanium System Administrator to determine the HIPS software used on the Tanium Clients. Review the settings of the HIPS software. Validate exclusions exist which exclude the Tanium program files from being restricted by HIPS. If exclusions do not exist, this is a finding.
