Survey on Cyber Security of Industrial Control Systems

Today all critical infrastructure and industrial systems apply network-based automation and control systems to monitor and control their processes. Safe، effective and efficient management، coordination and operation of these units are possible through these control systems. In other words، automation and control systems are considered as the brain and nervous systems of critical infrastructure and industrial systems. Using computer and information technology to enhance the quality، performance and reliability of control systems، caused them facing unexpected threats; Cyber attacks are the most important ones. Following the Stuxnet attack، Industrial Cyber Security (ICS) has become a serious challenge for control engineering studies. Over the last few years، many researches have been conducted in the field of ICS. In this paper، we survey the literature of this area from the perspective of control engineering to present an overview of this issue and informing experts of this field with the related importance and research opportunities.
