we were speaking about modeling for vpn systems, wait for a thread about air gapped networks to be fascinating enough and for me to stumble across it for me to give a wildly inappropriate but technically correct though complex and subjective answer.
however there is a significant issue with using hard drives to transfer data in airgapped networks without proper f-caging, optical transfer of data via taking a video of rapidly flashing QR codes is fairly secure when under enough blankets, but mylar shielding of walls and windows may be required depending on the adversary model.
