Trustix Distro

Linux, an open-source, community-driven, and secure operating system (OS), stands as a Unix-like platform utilized across various devices such as computers, servers, mainframes, mobile devices, and embedded systems.

Known for its stability, security, and open-source nature, Linux has become a go-to choice for individuals, businesses, and governments worldwide. One of the unique aspects of Linux is the availability of various Linux distributions, also known as "distros." These distributions combine the core Linux kernel with different software packages, configurations, best and the most secure operating systems, and philosophies, catering to specific needs and preferences.

In the latest version of this blog, we will discuss Trustix, a Linux distribution celebrated for its security and ease of installation media use, and explore modern Linux distributions used today to make security issues meet evolving user demands.

What is Trustix?

Trustix Linux emerged as a secure Linux distribution in the early 2000s, developed by the Norwegian company Trustix AS. Built upon the foundation of the Linux kernel, Trustix Linux quickly gained recognition for its robust security features and user-friendly approach.

With its proactive security measures, Trustix Linux incorporated system hardening techniques, access controls, and secure remote administration, ensuring a secure boot and solid foundation of identity protection for server and desktop environments. It leveraged technologies like grsecurity to enhance kernel security and OpenSSH for secure remote access to network calls.

One notable feature of Trustix Linux was its package management system called "swup" (Software Update Program). Swup was the most secure operating system, allowing users to easily install, update, and manage packages on their Trustix systems.

Key Features

  • Trustix Secure Linux was initially developed by Trustix AS. The company offered paid services, including support, training, and custom development. Robust security measures, system hardening techniques, and secure remote administration with OpenSSH integration. With a user-friendly interface for an intuitive experience. Automatic security updates through the swup package management system.

  • Server-oriented capabilities for reliable server infrastructure. Trustix Secure Linux is focused on providing a highly secure environment ideal for server usage. This was achieved by minimizing the number of installed packages to reduce the attack surface and providing automatic security updates. Extensive repository of software packages for easy customization. Trustix was not directly based on major Linux distributions like Debian, Fedora, or Arch Linux, although it shared the common Linux base.

  • Creation and History: Trustix was created in 1999 by Trustix AS, a company based in Trondheim, Norway. Trustix Secure Linux went through several versions throughout its life, with Trustix Secure Linux 3.0.5 being one of the last stable releases made available.

  • End of Life: Trustix AS filed for bankruptcy in 2005, and further development on Trustix Secure Linux was halted. After that, Comodo attempted to revive the distribution, but these efforts were ultimately unsuccessful.

  • Legacy: Even though Trustix Secure Linux is no longer maintained, its philosophy and design principles have had an impact on other Linux distributions, and its focus on security is echoed in many server-oriented distributions available today.

As Trustix Linux flourished, it faced several serious security issues, vulnerabilities, and challenges that eventually led to its discontinuation. The project's final release occurred in 2007, and since then, this Linux distribution has not received active maintenance or updates.
