Linux Hardening Guide

Linux is not a secure operating system. However, there are steps you can take to improve it. This guide aims to explain how to harden Linux as much as possible for security and privacy. This guide attempts to be distribution-agnostic and is not tied to any specific one.

DISCLAIMER: Do not attempt to apply anything in this article if you do not know exactly what you are doing. This guide is focused purely on security and privacy, not performance, usability, or anything else.

    obscurity is the best security!

    I bench YABS 24/7/365 unless it's a leap year.

    Use a distribution with an init system other than systemd. systemd contains a lot of unnecessary attack surface; it attempts to do far more things than necessary and goes beyond what an init system should do. An init system should not need many lines of code to function properly.

    It seems Debian and CentOS, two main distros are abandoning/or abandoned init.

    Sounds remarkably like some control panels. ;)
