What is Qubes OS?
Qubes OS is a security-focused, open-source operating system that is designed to provide better security and isolation for its users. Unlike traditional operating systems, Qubes OS uses a unique approach to security called "Security by Compartmentalization."
This approach involves separating different applications and tasks into isolated compartments, called "qubes," which are each assigned a specific level of trust. For example, you can have a qube for your personal documents, a qube for browsing the web, and a qube for running sensitive applications. This way, if one qube is compromised, the others remain secure and unaffected.
Qubes OS also provides other security features, such as strict isolation of networking and USB devices, enforced memory management, and compartmentalized cryptography. It is designed to be used on a variety of hardware, including laptops and desktops, and supports a range of applications, including web browsing, email, office productivity, and multimedia.
Qubes OS is free and open-source, which means that anyone can access the source code and contribute to its development. It is often used by journalists, activists, and security professionals who require a high level of security and privacy in their work.
