A method comprising may include storing, in a BIOS comprising a program of instructions executable by the processor and configured to cause the processor to initialize one or more information handling resources of an information handling system, a hardware profile of the information handling system, the hardware profile comprising identifying information of one or more information handling resources of the information handling system recorded during creation of the hardware profile. The method may also include, during a boot of the information handling system in a hardware verification mode, creating a new hardware profile comprising identifying information of the one or more information handling resources, comparing the new hardware profile to the hardware profile stored in the BIOS, and if the new hardware profile differs from the hardware profile stored in the BIOS, issuing an alert indicating potential tampering with hardware of the information handling system after creation of the profile.

Systems and methods for detecting hardware tampering of information handling system hardware

A method includes booting an information handling system, providing by an EFI of the information handling system a memory segment for a first EFI type memory access, reserving a first portion of the segment from access by an operating system of the information handling system, determining a size of the first portion, determining a size of a second portion of the segment based upon the size of the first portion, allocating a third portion of the segment for the first EFI type memory access, the third portion including the first portion and the second portion, and passing a memory map to the operating system, the memory map including the third portion, wherein the third portion is reserved from access by the operating system.

System and method for pre-operating system memory map management to minimize operating system failures

In accordance with embodiments of the present disclosure, a method may include generating a master cryptographic key for encrypting and decrypting the one or more variables stored in a non-transitory computer-readable medium accessible to a basic input/output system of an information handling system. The method may also include encrypting the master cryptographic key with a system password, such that the master cryptographic key as encrypted with the system password may be decrypted and used to encrypt and decrypt the one or more variables in response to entry by a user of the system password. The method may further include encrypting the master cryptographic key with an administrator password, such that the master cryptographic key as encrypted with the administrator password may be decrypted and used to encrypt and decrypt the one or more variables in response to entry by an administrator of the administrator password.
