Description
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, intrusion prevention system (IPS), encryption, or other security and management stack software may disallow the Client from working as expected. For more information, refer to https://docs.tanium.com/platform_deployment_reference/platform_deployment_reference/security_exceptions.html?Highlight=exclusion.

ℹ️ Check
Review the settings of the antivirus software. Verify exclusions exist that exclude the Tanium Client process interactions from On-Access scans and are treated as Low-Risk. If exclusions do not exist, this is a finding.

✔️ Fix
Implement exclusion policies within the antivirus software to exclude the On-Access scanning of Tanium Client process interactions. These processes should be treated as Low-Risk and not scanned during read or write events.
