When I was working server farms all external devices (ports, usb and drives) were disabled in the bios. It required admin rights to enable them and some of our extreme boxes, it took two people with admin rights to get to them.
Also, these servers were behind two sets of firewall hubs with another two sets where entering into the outside nets. I have read that these servers are directly connected to the net. Effin amazing
The more I read on the dominion boxes the more I realize just how vulnerable we are to fraud.
You’re speaking Ancient Sanskrit to the average state election bureaucrat who just recently learned to tie his\her shoes !
The machines should not be connected in any way. The fact that he plugged the Election Management System data into an external laptop and manipulated it in the file explorer before palming it is enough to consider the entire election in that county to be compromised.
