abstract: The aim of this paper is to review and discuss how the advances in stochastic modeling and analysis techniques could be successfully used in modeling and simulating Critical Information Infrastructures (CII). To protect critical infrastructures, it is necessary to study their complex system behavior, when they are stressed or attacked, and to understand the emergent phenomena originated by the individual behavior of the infrastructure components, operators and the environment. Therefore, as demonstrated by previous work on this subject, a challenge is to provide formalisms, methodologies, and tools to model the entire complex system. In this paper, we review the advances in stochastic modelling and simulation of complex systems, focusing on how such techniques can be applied to CII analysis. We also discuss their advantages and drawbacks, against, for example, the event-driven simulation approach in all its variants (e.g., agent-discrete simulation).
