Abstract

An information handling system may include a host system comprising a host system processor, a logic device configured to perform a functionality of the information handling system in accordance with code stored on non-transitory computer-readable media of the logic device, and a management controller communicatively coupled to the host system processor and the logic device and configured to perform out-of-band management of the information handling system. The management controller may be further configured to: during a boot of the management controller, perform an initial authentication of the code via an immutable interface of the logic device, after the initial authentication and prior to completion of boot of the management controller, enable a hardware lock to prevent write access to the logic device via the immutable interface, and in response to a power on request of the host system, perform a second authentication of the code via a mutable interface of the logic device.
