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?
I consider bootloader attacks a very low-probability threat, and quite honestly I don’t trust the average board vendor to produce anything that’s actually secure anyway. If I were in the habit of carrying a laptop back and forth across international borders I might feel differently, but for a desktop stuck in a room in Canada that hardly anyone enters when I’m not present, Secure Boot is a major hassle in return for a small security gain. So I just don’t bother.
