Qubes is a security-oriented OS that is designed to provide strong security through isolation. Built upon Xen, X Windows, and Fedora Core 18 (as of Qubes R2 beta 2), in Qubes both the components of the operating system and the user workspaces are isolated into functional domains, such as Dom0 for the GUI and user interaction through keyboard and mouse, NetVM and FirewallVM for the network stack, network drivers and network access control, and various user AppVMs for your applications and data.

Likewise, it can also be used to protect internet-facing services from 0-day vulnerabilities, or to harden legacy applications that are no longer supported by their vendors.
