A survey of SCADA test bed

The proliferation of computer network technology in Supervisory Control and Data Acquisition (SCADA) makes security issues more and more prominent. In order to protect the SCADA system, researchers should analyse potential vulnerabilities and propose relevant solutions to deal with malicious attacks. However, it is difficult to evaluate the abilities of the secure solutions being developed, because most research institutes lack modelling tools. Thus, building a SCADA test bed is indispensable to carry out some necessary experiments for evaluating those solutions before deployment. Relevant experiments can be conducted with such test beds. This paper analyses the construction schemes of the SCADA test beds proposed and shows the components and protocols used to construct such test beds. We also describe a series of attack experiments and mitigation strategies. Finally, we give the future directions in this research field.
