The assumption is that there can be no perfect, bug-free desktop environment: such an environment counts millions of lines of code and billions of software/ hardware interactions. Qubes implements a Security by Isolation approach. Other proposals of similar systems have surfaced and SecureView is a commercial competitor, however Qubes OS is the only system of the kind actively being developed under a free and open-source software (FOSS) license. Systems like Qubes are referred to in academia as Converged Multi-Level Secure (MLS) Systems. Qubes Windows Tools support Microsoft Windows 7 and later. Virtualization is performed by Xen, and user environments can be based on (with official support) Fedora or Debian, or (with community support "these templates may be somewhat less stable, since the Qubes developers do not test them") Whonix, Ubuntu, Arch Linux, CentOS, or Gentoo among other operating systems e.g. ![]() Qubes OS is a security-focused desktop Linux distribution that aims to provide security through isolation.
