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.

Hardening Arch Linux (monero.town)

Hi, I'm in a process of making fast, (extrenely) secure, and modern laptop. Currently I have Arch Linux with encrypted root partition (unlocked with Nitrokey or long password), secure boot, linux-hardened, firewalld, etc.

I'm running linux-hardened with custom config. I enabled AMD SME, kernel lockdown, added some xanmod patch for more specific cpus, and disabled some unnedded drivers (only those that I'm 100% sure I don't need - Intel, NVidia, Microsoft, Google, Amazon, Virtio). Currently it takes ~50 minutes to recompile the kernel. Are there any tutorials what drivers to disable to speed up this process? After doing that I will try to compile it with -O3 and LTO. Do you know any patches for performance?

I'm planning to enable encrypted swap, install ClaimAV and install flatpak versions for every non open-source app I have.

I also want to have SELinux. Does anyone know where can I learn it? I had it on Fedora and it was not fun using it.

What are other ways I can make my laptop more secure?

Look into installing AppArmor instead of SELinux. AppArmor is easier to configure, and SELinux is not officially supported on Arch.

I will try it out, thank you :)
