Abstract
A method, an information handling system (IHS) and a detection system for detecting runtime tampering of unified extensible firmware interface (UEFI) images in an IHS. The method includes retrieving, via a board management controller (BMC) from a first memory device, a first UEFI driver associated with a first component of the IHS. The method also includes generating a first hash of the first UEFI driver and retrieving, from a second memory device, a second hash associated with an initial first UEFI driver of the first component of the IHS. The method further includes determining if the first hash and the second hash match, and in response to the first hash and the second hash not matching, generating an error message that indicates detection of runtime tampering with the first UEFI driver and storing the error message to an error log.
