In the past, control networks were completely isolated from exterior attack with the use of proprietary control protocols running on specialized hardware and software. Since then, TCP/IP based systems have made their way into the industrial control system. Control networks based on TCP/IP provide better connectivity and remote access capabilities, making the industrial control system vulnerable to cyber threats such as computer virus, internet worm, manipulation of operational data which can result in the disruption of the entire control system. In this paper, security risks of the industrial control system based on control network are analyzed and the differences between the disruption of control performance and that of control function are presented. The countermeasures are put forward. © 2011 Springer-Verlag Berlin Heidelberg.
