Security by isolation
Qubes OS, whose main concept is “security by isolation” by using domains implemented as lightweight Xen virtual machines. It attempts to combine two contradictory goals: how to make the isolation between domains as strong as possible, mainly due to clever architecture that minimizes the amount of trusted code, and how to make this isolation as seamless and easy as possible.
