The most secure GNU / Linux distributions of 2018

Cyber ​​padlock

In these times it is good to have all possible shields and more to protect our teams. Many believe that Linux it is 100% and that is not true, in fact, no operating system or software of any kind is 100% secure. Nor does the hardware escape from vulnerabilities as we have seen with the latest Specter and Meltdown scandals, but there is something we can do and that is at least have a secure OS as a foundation.

Although Unix-like systems are not 100% secureThey are generally more secure than Microsoft Windows, as well as being open source and being able to subject their source code to scrutiny for vulnerabilities, intentional or unintended backdoors, etc. And if you want to know which are the safest distros that we have listed for this year that ends, 2018, I encourage you to continue reading our post:

  • WHAT IS IT?: it is an old acquaintance of LxA, since it is not the first time that we talk about it in this blog. This operating system, as we already have, has two virtual machines or virtualized environments to create a very secure isolation, separating processes. For this it makes use of the famous Xen hypervisor. Surely this sounds familiar to you from another old acquaintance, Whonix ... Eduard Snowden himself has spoken quite positively about this distro. Go ahead and try it! Official Web.
  • TAILS OS: also another one that we have talked a lot about on our blog and also related to Edward Snowden. In this case, more than security itself, this distro is a Debian-based one with a special emphasis on privacy and anonymity, avoiding leaving a trace when we surf the net. To get that extra security and privacy, it is downloaded in projects as well known as Tor. Also, it can be run in Live mode and consumes little RAM, making it quite light. Official Website!
  • HEADs OS: This is not such a well-known project, but it is also a 100% FOSS Linux distro that has arrived in the last year to position itself as a good alternative for TAILS, using some improvements to strengthen the security of the kernel (hardened kernel) and the use TOR-routed navigation. Official Website!
  • Whonix: there is little to say about this distro with almost paranoid security measures ... It is also based on Debian and runs two VMs. One of these virtual machines is the so-called workstation, that is, the one for the operating system. While the other, known as the gateway, is the one that carries the network traffic through Tor. Unlike Tails, which removes the previous state after restarting, in this case it is maintained, so it could be a problem ...  Official Website!
  • Subgraph OS: It is a project designed to be a robust platform, and its developers have worked hard to improve security. Edward Snowden has also complimented it, although keep in mind that in this case it is in an alpha phase of development, therefore, too early to recommend it until it matures something else.   Official Website!
  • OtherThere are many more, and even other non-Linux-based secure operating systems projects, I mean the BSD-based ones if you are interested. We could even cite other distros, like IprediaOS y Discreet Linux with important security and / or privacy improvements.

But if what you want is a more generic distro for day to day, you can opt for Debian or CentOS, which are two of the safest for most users.
