i wont use it, because i dont really understand half of what is written in the article, they lost me at Bare Metal Hypervisor, but what the hell is with the seemingly random picture of the woman with the scarfe around her neck?

The "bare metal hypervisor" is Xen. In a nutshell, it runs directly on the hardware of the server machine, and that is all it does (you install Xen, and it consumes the whole drive) You then install your operating systems virtually ontop of Xen. To access your operating system, you login to it from another machine using special Xen client software.

As Xen is what runs the amazon elastic cloud, there is need for high security OSes like Qubes for enterprise business applications.

Life always finds a way. I just wonder if you put a function for a USB and a function for an ethernet port in the same code, won't that start two kernels even if they are isolated and basically give you access to both in the same code? I might not be getting something, but I could see the same program having a hard time accessing all of the other kernels, since they are not in the same process. Could be good I guess, but I can see sorta a way around that if you have other malicious software already running hidden.

So this is essentially the same thing as Minix, only that it's been reinventing Minix again (just like about 20 other projects during the last 15 years that have never come as far as EU funded Minix which is even partially POSIX compatible)?

So what they are doing is sandboxing stuff into partitions using Xen ? WHY?
I am more interested how are they making the transition between the domains, because if they're using IOMMU to have a discrete videocard available to the domains, how are they sharing it between the domains ?

Tom's, you could make an article about virtualizing Windows 7 on top of xen with a normal Ubuntu install in dom0 and have a discreet videocard for windows 7 and use the integrated one for ubuntu/linux, like a sandy bridge igpu and some nvidia/radeon. If you prove that the transition between the domains is fast and easy, this would be AWESOME for regular linux users, as I hate to reboot to play some games. But that way, I could just switch between the domains, at any given time. I mean, RAM is cheap.

Lol there would be more comments on this particular article but veterans know they'd quickly get decimated with thumbs downs ;)

I won't even bother with mentioning "kitchen" in any context :D

You know, most viruses come from the internet. You could simply install VirtualBox and download Slitaz (a very small Linux LiveCD distribution - around 30 MB), and use that for your basic browser needs, completely separate from your main OS.

As long as you don't set up shared folders and only share the clipboard, you should be ok.

OpenBSD, SELinux, ... this sounds like a vaporware puff piece.

The NSA has been using(and actually wrote much of) SELinux for years, and it seems to be working out for them.

Except that if you follow the link you can download the beta?

She doesn't say much about microkernels. I would like to know what she thinks about this blog post about OKL4 : http://www.ok-labs.com/blog/entry/microkernels-vs-hypervisors/

By the way, the same people have created a version of L4 that, as I understand it, is formally verified to function exactly as specified, http://www.nicta.com.au/media/previous_releases3/2009_media_releases/world-first_research_breakthrough_promises_safety-critical_software_of_unprecedented_reliability . This should surely help to improve stability and security.

All there doing here is taking the same technology Sun Microsystems used to create Zones and repackaged it with Xen overhead. Look up Solaris 10 Trusted Extenstions .. same stuff..

This is the same woman who said she had a 100% undetectable virus a few years back. She was challenged at the Black Hat conference that year and wouldn't present it without a large upfront payment.

Do people still take her seriously?

I know of a 100% undetectable virus, its called origin. You can download it from EA.

The typical application for this Os would be secure environments like banking or government. It would be interesting to know if they will submit it for FIPS-140 approval.
