Title

The Tanium application must restrict the ability of individuals to use information systems to launch organization-defined denial-of-service (DoS) attacks against other information systems. (Cat II impact)

Discussion

The Tanium Action Approval feature provides a two-person integrity control mechanism designed to achieve a high level of security and reduce the possibility of error for critical operations and DoS conditions. 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.
