I have extended the Self-Defense BaseCamp – the entry point to privacy defense and online security – with an article on security for computers running Microsoft Windows, Apple macOS and Linux.
In the first section, I give a brief assessment of security and protecting your privacy when using Windows, macOS, or Linux. Since there is not only one Linux, I focus on Ubunto and Linux Mint. These are two popular beginner-friendly Linux variants.
Section 2-5 is about making your operating system more secure and also more “private”. You will find there configuration recommendations that you can implement step by step on your computer.
Have fun working through it.
