Abstract
A method and an information handling system (IHS) for authenticating boot path updates in an IHS. The method includes initializing, by an image loader of the IHS, a current boot path associated with a first image. The method also includes detecting, by a processor of the IHS, detecting an attempt to update the current boot path to utilize a second image that is different from the first image. The method further includes, in response to detecting the attempt to update the current boot path, initializing a pre-authentication process to authenticate the second image. The method further includes, in response to the pre-authentication process authenticating the second image, updating the current boot path to utilize the second image and enabling a subsequent boot of the IHS using the second image.
