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?
Okay, so my original post I think I was thinking of TPM rather than Secure Boot. TPM would protect against a hostile OS, I think. I think most of my greviences mentioned above are to do with TPM rather than Secure Boot. But they still apply to either.
There are ways to put keyloggers in devices stealthily to where they’re not perceptible to a normal person. For example, they could replace one of the USB leads in your bag with one that transmits keystrokes over bluetooth. If you’re at home, a maid could just plug a keylogger behind your desktop because most people don’t check behind their system when they boot it.
It all feels like a wierd threat model to me. You can either assume that physical access is or isn’t covered by it. If you are worried about physical access (beyond your device being stolen), there is a lot more you need to do to secure it. “It’s better than nothing” isn’t really that convincing to me with regards security models; either you’re protected or you aren’t.
