Cyber security issues of critical components for industrial control system

The increasing interconnectivity of industrial control system (ICS) networks has exposed them to a wide range of security problems. In recent years, efforts from industries and research communities have been made in addressing the security issues of ICSs. However, the ICSs security for critical infrastructures is still a challenging issue today. Controller, supervisory software and control network are critical components of ICS, and those components, many designed without security in mind, are vulnerable to cyber-attacks and any of them attacked easily lead to system collapse. Much research work about this subject has been done and a lot of vulnerabilities and countermeasures were presented. In this paper, we surveys ongoing research and provide an overview of the cyber security of controller, supervisory software and control network.
