Cyber-physical testbed ? The impact of cyber attacks and the human factor

The case of Critical Infrastructures (CIs), and especially Cyber-Physical CIs, which nowadays rely on computers and the Internet for their operation, is an important research area. Decentralized Critical Infrastructure management systems play a key role in reducing costs and improving the quality of service of industrial processes, but also they introduce various security vulnerabilities. In this paper, we focus on the implementation of a Cyber-Physical testbed which includes physical equipment and the cyber security issues on the communication channel between the CIs, such as a power grid, a transportation infrastructure (railway) and the energy market. We simulate the energy (spot) market auctions and the power grid network, but we emulate the ICT information part which is the focus of our work. We set in motion a well-known attack, Denial-of-Service (DoS), in Cyber-Physical systems and we are able to identify the consequences not only in power distribution network but also in financial and transportation area.
