Testbed techniques of industrial control system

Industrial control system (ICS) plays an important role in the critical infrastructure, and any compromise in their security can result in grave consequences. Since the occurrence of “Stuxnet” event in 2010, the information security problems of ICS cause the intense attentions all over the world. How to assure the security of ICS has become a hot topic in governments, industrial sectors and academic community around the world. Currently, testbed technique has become an important and effective simulation solution for checking vulnerabilities and validating security solutions of ICS. In this paper, we review the existing research results of ICS testbeds in government sectors and academic community respectively, and analyze their functions and simulation capability. Furthermore, we make a discussion of ICS testbeds and a comparison of ICS testbeds in academic community. From this work, researchers can clearly know the status of ICS testbeds and promote the further searches in this hot field.
