Title

The Tanium Action Approval feature must be enabled for two person integrity when deploying actions to endpoints. (Cat II impact)

Discussion

The Tanium Action Approval feature provides a "four eyes" control mechanism designed to achieve a high level of security and reduce the possibility of error for critical operations. When this feature is enabled, an action configured by one Tanium console user will require a second Tanium console user with a role of Action Approver (or higher) to approve the Action before it is deployed to targeted computers. While this system slows workflow, the reliability of actions deployed will be greater on the Packaging and Targeting.
