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?
Just because they can do X doesn’t mean you shouldn’t protect against Y.
Just as an example scenario, say border guards took my laptop out of my eyesight. A camera or USB keylogger won’t do anything in that case. Hijacking my bootloader though potentially gives them access to my machine without me having any clue.
Secure Boot is useful and worth setting up. But everyone has to decide their own level of comfort when it comes to security.
