Idk if FDE is enough, what if the attacker can modify the boot code to capture the decryption keys and other stored passwords ? as far as I know this is exactly what secure boot protects against, it checks the validity of the boot code using the TPM chip, if it's already there, why don't most distros use it ? instead you'll see that secure boot is greyed out in the Bios ( which means it's not supported )
and yes, I did lock down the Bios too, with a different password
Edit: I'll check EndevourOS documentation, Mint is cool but it doesn't adobt newer standards or newer kernels ( newer kernels are just much more secure )
Oh, I never heard of this one before, it certainly meets the criteria, I read the documentation to understand it more
yes, the developer seem very opinionated :|
