Probably one of the most important things we can do well. When involved in this space in the 80s, things were far less connected, so both the threats and remedies are far more possible. Here an overview of SCADA. And add to that the ability to find patterns of much more subtle changes in a system.
Protecting Industrial Control Systems By Keith Kirkpatrick

While most commercial and government organizations have a corporate network to handle administrative, sales, and other back- or front-office data, a growing number of organizations also have implemented one or more supervisory control and data acquisition (SCADA) systems. These systems incorporate software and hardware elements that allow industrial organizations, utility companies, and power generators to monitor and control industrial processes and devices, including sensors, valves, pumps, and motors. Today's SCADA systems also allow organizations to harvest data from these devices, and then to analyze and make adjustments to their operational infrastructure to improve efficiency, make smarter decisions, and quickly address system issues to help mitigate downtime. ....
