QUBES OS

Qubes implements Security by Isolation approach. To do this, Qubes utilizes virtualization technology, to be able to isolate various programs from each other, and even sandbox many system-level components, like networking or storage subsystem, so that their compromise don’t affect the integrity of the rest of the system.
Qubes lets the user define many security domains implemented as lightweight Virtual Machines (VMs), or “AppVMs”. E.g. user can have “personal”, “work”, “shopping”, “bank”, and “random” AppVMs and can use the applications from within those VMs just like if they were executing on the local machine, but at the same time they are well isolated from each other. Qubes supports secure copy-and-paste and file sharing between the AppVMs, of course.

Key architecture features:

Based on a secure bare-metal hypervisor (Xen)
Networking code sand-boxed in an unprivileged VM (using IOMMU/VT-d)
No networking code in the privileged domain (dom0)
All user applications run in “AppVMs”, lightweight VMs based on Linux
Centralized updates of all AppVMs based on the same template
Qubes GUI virtualization presents applications like if they were running locally
Qubes GUI provides isolation between apps sharing the same desktop
Storage drivers and backends sand-boxed in an unprivileged virtual machine()
Secure system boot based on Intel TXT(

I think this is worth developing.

This was posted before :wink:

She also announced support for a Windows VM after the stable release.

Oh! Thanks for pointing that out. thought It’d be here in other security products section so i searched only here and got nothing. ;p

To be noted also Qubes OS couldn’t be installed in a virtual machine; only on real machine and 64bits.

Yes, so there really isn’t any other way to test it out other than using an actual installation.
