Abstract:
Systems and methods for detecting IHS attacks by monitoring chains of configuration changes made to Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) attributes are described. In some embodiments, an 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: monitor a chain of BIOS/UEFI configuration changes; compare the chain of BIOS/UEFI configuration changes against an Indication of Attack (IoA); and report an alert in response to the chain of BIOS/UEFI configuration changes matching the IoA.
