A framework for modeling interdependencies in Japan's critical infrastructures

Abstract

This paper discusses Japanese efforts related to critical infrastructure protection, including several case studies to clarify the risk components and countermeasures. An interdependency modeling framework that combines the inoperability input-output model (IIM) for economic interdependences and Bayesian networks for operational dependencies is presented. Also, the paper provides new multidimensional measures for interpreting interdependency modeling results. © IFIP International Federation for Information Processing 2009.
