Abstract:

A method may include determining if both of two redundant operating system images for executing functionality of a chassis management controller were found during one or more previous boot sessions of the chassis management controller to be unsecure, wherein each operating system image comprises an integrated kernel and initial file root system stored in a respective first partition of a memory of the chassis management controller, verity hashes of a root file system of such operating system image, the verity hashes stored in a respective second partition of the memory, and the root file system of such operating system image stored in a respective third partition of the memory. The method may also include, in response to determining that one of the two redundant operating system images is secure, initiate verification of such operating system image to determine if such operating system image has indicia of tampering.

International Classification:

G06F 21/57
G06F 21/64

Abstract:

A verification for a secure boot process may include determining a determined signature for a compendium stored in a memory where the compendium includes a bootloader and an operating system, accessing a verification signature corresponding to the compendium, and comparing the verification signature with the determined signature where if the verification signature is the same as the determined signature, the compendium is verified as secure and a secure boot process is performed with the bootloader and operating system. The compendium may include one or more applications such that the applications may be verified as secure with the verification signature.

International Classification:

G06F 21/57
G06F 12/00

Abstract:

A service processor of an information handling system receives a Secure Boot database from a provisioning server coupled to the service processor by a data communication network. The Secure Boot database is stored at a memory device included at the service processor. The Secure Boot database is provided to a basic input output system (BIOS) at the information handling system in response to a request issued by intrinsic BIOS instructions executed during initialization of the information handling system.
