Qubes Privacy Operating System


Qubes OS is a security-oriented operating system (OS). The OS is the software that runs all the other programs on a computer. Some examples of popular OSes are Microsoft Windows, Mac OS X, Android, and iOS. Qubes is free and open-source software (FOSS).

Supreme Isolationism

Qubes locks down each part of the OS by compartmentalizing it. Each component of the OS is relegated to a domain structure that is isolated from all other domains.

The concept is a bit strange to grasp until you see it in operation. You can have multiple domains running on the desktop at the same time. They appear on the screen as windows running applications in a traditional Linux desktop.

The applications actually are running in separate VM windows within the Qubes OS. The barriers between domains are rigidly enforced — even performing copy and paste operations from one domain window to another requires menu-driven procedures and authorizations.

The Qubes OS runs multiple color-coded Xen virtual machines as isolated windows that raise the bar for security.

This security barrier concept ensures that rogue code or other harmful intrusions in one domain do not affect any other component in the Qubes OS. A self-destructing domain brings an added security option.
