This International Standard provides requirements and guidelines for preventing the unauthorizedmodification of Basic Input/Output System (BIOS) firmware on PC client systems. Unauthorized modificationof BIOS firmware by malicious software constitutes a significant threat because of the BIOS’s unique andprivileged position within the PC architecture. A malicious BIOS modification could be part of asophisticated, targeted attack on an organization —either a permanent denial of service (if the BIOS iscorrupted) or a persistent malware presence (if the BIOS is implanted with malware).As used in this publication, the term BIOS refers to conventional BIOS, Extensible Firmware Interface (EFI)BIOS, and Unified Extensible Firmware Interface (UEFI) BIOS. This International Standard applies tosystem BIOS firmware (e.g., conventional BIOS or UEFI BIOS) stored in the system flash memory ofcomputer systems, including portions that may be formatted as Option ROMs. However, it does not apply toOption ROMs, UEFI drivers, and firmware stored elsewhere in a computer system.Subclause 7.2 provides platform vendors with requirements for a secure BIOS update process.Additionally, subclause 7.3 provides guidelines for managing the BIOS in an operational environment.While this International Standard focuses on current and future x86 and x64 client platforms, the controlsand procedures are independent of any particular system design.
