Cyber Risks in Energy Grid ICT Infrastructures

The objective of the chapter is to present the role of cyber security experiments within a methodological approach for the evaluation of cyber risks in grid control systems. As a starting point, a cyber-power risk index has been defined to support the identification of relevant risk factors across network attack models. Instances of attack models have been then experimented on an ICT architecture implementing grid operation scenarios with the double aim of evaluating the attacks’ effects by means of communication performance measures and of tuning the configuration of security mechanisms. The chapter discusses the results of a variety of attack experiments and their role in the calculation of the risk index.
