A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
Arch Linux is an independently developed x86-64 general-purpose Linux distribution that strives to provide the latest stable versions of most software by following a rolling-release model. The default installation is intentionally minimal so that users can add only the packages they require.
This is a list of operating systems specifically focused on security. Similar concepts include security-evaluated operating systems that have achieved certification from an auditing organization, and trusted operating systems that provide sufficient support for multilevel security and evidence of correctness to meet a particular set of requirements.
seccomp is a computer security facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit , sigreturn , read and write to already-open file descriptors. Should it attempt any other system calls, the kernel will either just log the event or terminate the process with SIGKILL or SIGSYS. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.
Fedora Linux is a Linux distribution developed by the Fedora Project. It was originally developed in 2003 as a continuation of the Red Hat Linux project. It contains software distributed under various free and open-source licenses and aims to be on the leading edge of open-source technologies. It is now the upstream source for CentOS Stream and Red Hat Enterprise Linux.
Lynis is an extensible security audit tool for computer systems running Linux, FreeBSD, macOS, OpenBSD, Solaris, and other Unix derivatives. It assists system administrators and security professionals with scanning a system and its security defenses, with the final goal being system hardening.
NixOS is a free and open source Linux distribution based on the Nix package manager. NixOS uses an immutable design and an atomic update model. Its use of a declarative configuration system allows reproducibility and portability.
Solus is an independently developed operating system for the x86-64 architecture based on the Linux kernel and a choice of Budgie, GNOME, KDE Plasma or Xfce as the desktop environment. Its package manager, eopkg, is based on the PiSi package management system from Pardus Linux, and it has a semi-rolling release model, with new package updates landing in the stable repository every Friday. The developers of Solus have stated that Solus was intended exclusively for use on personal computers and will not include software that is only useful in enterprise or server environments.
Qubes OS is a security-focused desktop operating system that aims to provide security through isolation. Isolation is provided through the use of virtualization technology. This allows the segmentation of applications into secure virtual machines called qubes. Virtualization services in Qubes OS are provided by the Xen hypervisor.
elementary OS is a Linux distribution based on Ubuntu LTS. It promotes itself as a "thoughtful, capable, and ethical" replacement to macOS and Windows and has a pay-what-you-want model. The operating system, the desktop environment, and accompanying applications are developed and maintained by elementary, Inc.
Whonix is a Linux distribution, based on Kicksecure OS, claimed to be security hardened by its developers.
Void Linux is an independent Linux distribution that uses the X Binary Package System (XBPS) package manager, which was designed and implemented from scratch, and the runit init system. Excluding binary kernel blobs, a base install is composed entirely of free software.
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to also work for Internet of Things devices and desktop applications.
Flatpak is a utility for software deployment and package management for Linux. It is advertised as offering a sandbox environment in which users can run application software in isolation from the rest of the system. Flatpak was known as xdg-app until 2016.
Cub Linux was a computer operating system designed to mimic the desktop appearance and functionality of ChromeOS. It was based on Ubuntu Linux LTS 14.04 "Trusty Tahr". It used Openbox as the window manager and tools taken from LXDE, Gnome, XFCE as well as a number of other utilities. It was a cloud-centric operating system that was heavily focused on the Chromium Browser. Cub Linux's tagline was "Cub = Chromium + Ubuntu".
postmarketOS is an operating system primarily for smartphones, based on the Alpine Linux distribution.
IPFire is a hardened open source Linux distribution that primarily performs as a router and a firewall; a standalone firewall system with a web-based management console for configuration.
KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the LibreOffice office suite, and other popular software applications that use the Qt toolkit.
Azure Linux, previously known as CBL-Mariner, is a free and open-source Linux distribution that Microsoft has developed. It is the base container OS for Microsoft Azure services and the graphical component of WSL 2.
