Joanna Rutkowska Releases 'Qubes' Hardened OS
Joanna Rutkowska, a security researcher known for her work on virtualization security and low-level rootkits, has released a new open-source operating system meant to provide isolation of the OS's components for better security.
The OS, called Qubes, is based on Xen, X and Linux and is in a basic, alpha stage right now. Qubes relies on virtualization to separate applications running on the OS and also places many of the system-level components in sandboxes to prevent them from affecting each other.
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.
