Abstract
Examples disclosed herein relate to a computing device that includes a central processing unit, a management controller separate from the central processing unit, and a security co-processor. The management controller is powered using an auxiliary power rail that provides power to the management controller while the computing device is in an auxiliary power state. The security co-processor includes device unique data. The management controller receives the device unique data and stores a representation at a secure location. At a later time, the management controller receives endorsement information from an expected location of the security co-processor. The management controller determines whether to perform an action on the computing device based on an analysis of the endorsement information and the stored representation of the device unique data.
