NIST is releasing a publication that will help organizations prepare better against potentially destructive attacks to the collection of hardware and firmware components of a computer system, also called the platform. Special Publication 800-193, Platform Firmware Resiliency Guidelines provides technical guidelines and recommendations supporting resiliency of platform firmware and data against such attacks. These guidelines describe security mechanisms for protecting the platform against unauthorized changes, detecting unauthorized changes that occur, and securing recovery from attacks. This document is intended to guide implementers, including system manufacturers and component suppliers, on how to use these mechanisms to build a strong security foundation into platforms.
