Abstract
Systems, computing devices, and methods for authenticating privileged subsystem access by policy and by use of a security key generated at boot are disclosed herein. According to an aspect, a method includes generating a security key upon boot of a host-facing interface for a client. The method also includes communicating the security key to a baseboard management controller. Further, the method includes authenticating, to the host-facing interface commands, based on the security key. The method may also include implementing a policy associated with the security key. Further, in response to determining that a received command is not allowed by policy or the security key is not authenticated, an external server port or debug header may be disabled to prevent execution of the command.
