Why didn't anyone ask Dominion in Michigan if their machines have an inbuilt FIREWALL? I was waiting for this but it never came up? If someone connected the voting machine network to the internet (either by accident or mistake) ALL the machines are open to attack. They didn't even ask if the voting machine devices used encrypted communication between each other. Didn't ask if voting systems had any network intrusion protection/alerting either. They really need someone technical advising them on their questioning. Zzz
