Abstract

In this paper we report on a recent study of the impact of cyber-attacks on the resilience of complex industrial systems. We describe our approach to building a hybrid model consisting of both the system under study and an Adversary, and we demonstrate its use on a complex case study - a reference power transmission network (NORDIC 32), enhanced with a detailed model of the computer and communication system used for monitoring, protection and control. We studied the resilience of the modelled system under different scenarios: i) a base-line scenario in which the modelled system operates in the presence of accidental failures without cyber-attacks; ii) scenarios in which cyber-attacks can occur. We discuss the usefulness of our findings and outline directions for further work.
