Is Heads necessarily more secure?

[newbie]

hi @Insurgo , this is to continue the discussion in firmware backdoor
about recommendation to replace some peripherals in our computer,
although already flashing with heads.

@Insurgo

Is my only relevant answer to this thread outside of how Qubes prevents compromise, permits auditability of compromise and recovery. That is on top of a firmware that can be audited and auditable. On top of a reasonably secure computer, that is. You computer has EC controller firmware, which Heads cannot reprogram (Lenovo BIOS updater can), SSD drive firmware. Of course, there is firmware as well into other peripherals in your computer, one of which is recommended to be replaced, which is your wifi card.

so, what’s the reason behind to replace wifi card ?
how about bluetooth module, ram, ssd, harddisk ? recommended to replace too ?
is there a recommended wifi card to improve security ?

thanks and regards,
