![]() ![]() ![]() With Secure Boot active, the firmware checks for the presence of a cryptographic signature on any EFI program that it executes. Secure Boot, though, is designed to add a layer of protection to the pre-boot process. Until late 2012, this has been true of most production EFI implementations, too. By executing before an OS kernel gains control of the computer, malware can "hide out" in ways that aren't possible once an OS has taken over, thus making it virtually impossible for virus scanners to detect the malware-at least, not without rebooting into an emergency system that's not infected.īIOS provides few protections against infection by pre-boot malware in the BIOS boot path, the OS implicitly trusts whatever executes as the boot loader. Although other modes of virus transmission gained prominence as floppies faded in importance and Internet connections became common, pre-boot malware has always had its appeal to malware authors. Some of the earliest viruses for PCs spread as boot sector viruses: They resided as code in the boot sectors of floppy disks and spread from one computer to another when users booted their computers using infected DOS floppies. In other words, things may have changed! What Is Secure Boot?įor decades, PCs have been plagued by viruses, worms, and other malware. Although Secure Boot is developing less rapidly than it was in late 2012, when I first wrote this page, it's still a dynamic area. This page provides an overview of what Secure Boot is and how the Linux community is responding to it. By its very nature, though, Secure Boot can also make it harder to boot Linux, particularly on commodity PCs that ship with Windows pre-installed. As the name implies, Secure Boot is intended as a security feature. In addition to implementing a new boot protocol, UEFI adds a new feature that can improve system security, but that also has the potential to cause a great deal of confusion and trouble: Secure Boot.
