Windows The story about how secure boot for Windows 8, part of UEFI, will hinder the use of non-signed binaries and operating systems, like Linux, has registered at Redmond as well. The company posted about it on the Building Windows 8 blog - but didn't take any of the worries away. In fact, Red Hat's Matthew Garrett, who originally broke this story, has some more information - worst of which is that Red Hat has received confirmation from hardware vendors that some of them will not allow you to disable secure boot.

Part of UEFI design is that you cannot probe from OS side what keys are in the store. So yes it will be leap of faith at times if you try just putting up signed boot-loaders guessing what key works. This is about making attackers life harder.

So providing multi copies of the bootloader are not going to cut it either. Also once key is breached you don't want to keep on using it. Since attackers these days are after to place bootloader before OS so anti malware software inside the OS cannot detect the virus /bot/worm is there. Breached key equals exploited OS at core.

So yes only way to see what keys are in there would basically have something in the bios dialogs to show you. This is also useful for techs debuging why something has gone south. Go into bios look at the keys and go o boy that bios needs a update. If you can add keys you could just add the missing one remove the now expired one problem solved.

Now if you have to go by bios version numbers to makers site to find out if a particular version of windows can be installed is going to be a complete pain in but.

nonoitall the average user has nothing todo with why the secuirty is being done in the first place. What has better chance of average user being able to cope with secure boot. Having to visit a makers site or being able to check page in bios for what is supported. Having to check page in bios for what is support is closer average users skill limits.

Many windows machines are being exploited by malware/bot/worm/virus boot loader that effectively render all forms of detection of infection bar booting from different media almost impossible.

The prime reason for this is not DRM. Its the rate of infected machines out there. Something has to be done when more and more users are getting infected and the infection not being detectable.

Breach of DVD and Blueray is not a major problem. Reason what can you make a Blueray machine do by the breach nothing. What can you make a standard computer do when you breach it.

List of items.
Send spam
DDOS attack
Infect Others
Steal Identities
Steal person money and many other evils.

Basically if we want to stop OS being infected we need auditing from boot up all the way to user applications. This is many times more effective than anti-virus software. White listing. If only white listed stuff can work areas that can be infected are reduced.

Mandatory secure boot I have no problem with as long as I can add my own keys when I want to. And remove keys I know they are breached.

Most of the Linux world would not care either if they can added the keys required.

Simple fact here the rate viruses are growing its getting too cpu consuming to be working by black list. Items like secure boot based on public key encryption has to come.

So secure boot provides the promise of less anti-virus scanning required.

Most import is the implementation is sane for consumers. Microsoft current implementation fails the sane test. Insane to take too much control out of consumers hands and transfer to hardware makers.
