Abstract
A method may include storing a first set of secrets associated with an information handling system in a credential vault of a management controller configured to be coupled to a processor of a host system of the information handling system in order to provide management of the information handling system via management traffic communicated between the management controller and an external management network such that the first set of secrets are accessible responsive to a verified boot of the management controller and storing a second set of secrets associated with the information handling system in a storage of a cryptoprocessor owned by the management controller such that access to the second set of secrets may be granted in response to an administrator's provision of authorization to the cryptoprocessor, and such that access to the second set of secrets is prevented during runtime of the host system in absence of authorization.
