BIOS Protection Guidelines

    BIOS Protection Guidelines

    Minimize security risks by implementing protective measures that make your desktop and mobile workstations less vulnerable to BIOS-targeting malware.

    Modern computers rely on fundamental system firmware, commonly known as the system
    Basic Input/Output System (BIOS), to facilitate the hardware initialization process and
    transition control to the operating system. The system BIOS is typically developed by
    both original equipment manufacturers (OEMs) and independent BIOS vendors, and is
    distributed to end users by motherboard or computer manufacturers. Manufacturers
    frequently update system firmware to fix bugs, patch vulnerabilities and support new

    Malicious code in the system BIOS is a significant security threat because the BIOS
    executes very early in the boot process and initializes many key hardware and software
    components. While there are a variety of threats to the integrity of the system BIOS,
    this guide is focused on preventing the update of the system BIOS by malicious
    software. The security controls and procedures specified in this document are oriented
    to desktops and laptops deployed in enterprise environments.
