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.

How do you secure your bootloader without secure boot or why doesn't it matter? (lemmy.world)

I've made the effort to secure mine and am aware of how the trusted protection module works with keys, Fedora's Anaconda system, the shim, etc. I've seen where some here have mentioned they do not care or enable secure boot. Out of open minded curiosity for questioning my biases, I would like to know if there is anything I've overlooked or never heard of. Are you hashing and reflashing with a CH341/Rπ/etc, or is there some other strategy like super serious network isolation?

Don't trust Secure Boot.

That's the second best thing as long as you don't worry about nation state actors (you're fucked by then anyway). Only requirement is a board/laptop manufacturer with a proper uefi setup (eg ability to set your own keys, not using those "do not use" test keys, etc) - that usually comes with business machines.
