Qubes OS 4.2.2 (2024) 64bit Live Bootable DVD DL Secure Linux Operating System
Qubes OS is a free and open-source, security-oriented operating system designed for single-user desktop computing. It utilizes Xen-based virtualization to create and manage isolated compartments known as qubes, which are essentially secure virtual machines (VMs) with specific purposes, natures, and levels of trust. These qubes can be full-fledged or stripped-down VMs based on various operating systems like Fedora, Debian, and Windows, and they are visually distinguished by unforgeable colored window borders for easy identification of their security levels.
Qubes OS is particularly noted for its strong isolation features, allowing users to separate different software as if they were installed on separate physical machines. It also includes a unique Template system for sharing a root file system among app qubes without compromising security, and it supports the use of multiple operating systems simultaneously. With integrated Whonix support, Qubes OS enables safe and easy system-wide use of the Tor network for enhanced privacy.
Due to its technical nature and focus on security through compartmentalization, Qubes OS is recommended for users with prior experience in Linux. It’s an innovative approach to digital security, providing a way to manage activities and data across various secure compartments.
