A Review of Intrusion Detection Systems for Industrial Control Systems

Industrial Control Systems are found often in industrial sectors and critical infrastructures to monitor and control industrial processes. Recently, the security of industrial control systems has gained much attention as these systems now exhibit an increased interaction with the Internet. In fact, classical SCADA systems are already lacking with security problems, and with the increased interconnectivity to the Internet, they are now exposed to new types of threats and cyber-attacks. Intrusion detection technology is one of the most important security solutions used today in industrial control systems to detect potential attacks and malicious activities. This paper summarizes previous work for Intrusion Detection Systems approaches in Industrial Control Systems and highlights challenges and opportunities in implementing such solutions. We believe that such insights are valuable for further research in the industrial security context.
