Industrial Network Security...or lack of....

Ever since Shodan came along, we will be seeing more of this in industrial settings. The big issue is the industrial controls that control material handling, processing, and manufacturing. These systems/networks MUST be air gapped (although that is not full proof as we have seen with the Stuxnet worm) to increase the difficulty level of performing a breach to very difficult to impossible for hackers, crackers, and state sponsored actors. Additionally, epoxy the USB ports and disconnect the optical drives so that nobody can slip something onto the network (not fool proof, but it does help).

Air gaped networks force an intruder to perform a up-front intrusion (they have to be on site). Physical security is another matter though.
