Critical infrastructures, such as electricity generation plants, transportation systems, oil refineries, chemical factories and manufacturing facilities are large, distributed complexes. Plant operators must continuously monitor and control many different sections of the plant to ensure its proper operation. During the last decades this remote command and control has been made feasible due to the development of networking technology and the advent of Industrial Control Systems (ICS). ICS are command and control networks and systems designed to support industrial processes. The largest subgroup of ICS is SCADA (Supervisory Control and Data Acquisition) systems.
