Securing industrial systems is a major problem. Security - when not done perfect - is a disruption into efficiency, usability, and functionality. If you calculate the expected cost of a hack vs. the expected value of rebuilding the electronic infrastructure, in some situations being hacked is cheaper. Further, being hacked is rolling the dice... there is a probability it won't happen. Whereas, an electronic infrastructure rebuild is a guaranteed expense... and expensive. Then there's the Columbine mentality, "It could never happen here". That's pretty pervasive.
