From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux security (feddit.dk)

Hi there,

Win10 is soon not supported. Tbh Linux have been on my radar since I started to break from the US big tech.

But how is security handled in Linux? Linux is pretty open-source, or am I not understanding it correctly. So how can I as a new user make sure to have the most secure machine as possible?

To have the most secure machine possible, you might need a hardened kernel but you absolutely need to have SELinux (or equivalent) rules set up.

The easiest way to have a go at this would be to install OpenSuSE (any version will do, they all ship with SELinux ootb) and follow guides on how to setup SELinux permissions.
