The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to Contributions welcome!

This page explains how coreboot can help with various security aspects of your system, compared to closed-source, legacy BIOS/EFI/firmware implementations.

This page is work in progress!

Common security features

  • Boot password (like BIOS password)
  • RAM wiping after each boot
  • Signature verification - option to boot from payload only signed images
  • Support to encrypted block devices/volumes

Bayou / coreinfo have "BIOS password"-like feature, using SHA-1 hashes stored in NVRAM or the (flash) ROM chip.

Coreboot can be full-secure solution for your hardware, without this issues, which have "legacy" BIOS:

Current BIOS issues

RAM wiping

SMI issues

ATA issues

Firewire issues

TPM issues
