Guidelines for Protecting Basic Input/Output System (BIOS) Firmware
Shirley M. Radack
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-147, BIOS Protection Guidelines: Recommendations of the National Institute of Standards and Technology. The publication was written by David Cooper, William Polk, Andrew Regenscheid, and Murugiah Souppaya of NIST. The guidelines assist organizations in protecting the security of their systems and in preventing the unauthorized modification of BIOS firmware on PC client systems. Modern personal computers (PCs) rely on the Basic Input/Output System (BIOS) to perform fundamental systems functions when the computer is turned on. The bulletin discusses the contents of the publication, including the security concerns and threats to BIOS firmware, security practices for a secure BIOS update process, and the management best practices, which complement the security guidelines. References are provided to NIST publications that support system BIOS developers, vendors and user organizations.
