UEFI security startup hacker Win8 security still needs to strengthen

Computer store news All Windows 8 hardware devices will default to UEFI (Unified Extensible Firmware Interface) Secure Boot (Secure Boot), Prevents the unauthorized boot loader (OS Loader) from starting in the BIOS, UEFI only launches the authenticated boot loader, and malware can no longer use this method to attack users.

Of course, this has caused dissatisfaction in the Linux community, although Microsoft said that this will not shut down other operating systems (by setting PC firmware can control any operating system to perform a secure boot, not just Windows System), the Free Software Foundation (FSF) also called on everyone to boycott Microsoft's move, which means that computers that are certified by Microsoft cannot start an unauthorized operating system, "Safe Boot" should be called “Limited startup”.

Fedora and Red Hat have found a way to sign an agreement with Microsoft to provide their own Windows 8 system-compatible UEFI secure launch button via electronic signature. Many Linux enthusiasts hate this compromise, but they can't help it. However, Linus Torvalds, the father of Linux, did not agree with this.

Linus Torvalds said: "I am certainly not a UEFI fan, but I understand why you want to sign up and so on." ” Torvalds believes that Microsoft's Windows 8 UEFI secure boot does not really make the system secure.

& ldquo; I think the real problem is that smart hackers will bypass the entire certification issue. Signing is a very useful tool, but it doesn't solve all the security problems, and I think some people care a little about it. ”
