Systems and methods for preventing attachment of malign code to unused firmware memory are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: read contents of a non-volatile memory (NVM); and determine that the NVM does not include malign code stored thereon, at least in part, by determining that selected memory locations in the NVM where firmware is not stored contain pre-determined values.

Detecting malign code in unused firmware memory

In accordance with embodiments of the present disclosure, a method may include storing a system fingerprint of an information handling system, the system fingerprint comprising information associated with one or more information handling resources of the information handling system recorded during creation of the system fingerprint including information regarding a security seed, wherein the security seed comprises a value stored at a location of a non-transitory computer readable medium integral to an information handling resource of the one or more information handling resources. The method may also include during a verification mode, based on the information in the system fingerprint, determining whether potential tampering of the information handling system has occurred, and if potential tampering has occurred, issuing an alert indicating potential tampering with the information handling system.

Systems and methods for detecting tampering of an information handling system

A method may include: calculating approximate power requirements of components, the components supplied with electrical energy from a plurality of power supplies, each of one or more of the plurality of power supplies capable of being enabled and disabled from supplying electrical energy to the components; determining a set of possible configurations of the plurality of power supplies such that for each possible configuration, enabled power supplies of the possible configuration have adequate aggregate capacity to deliver the approximate power requirements and switching to the possible configuration from a then-present configuration would require no more than one of then-disabled power supplies be enabled and no more than one of then-enabled power supplies be disabled; and determining which of the set of possible configurations has the highest expected power efficiency.
