Empirical findings on European critical infrastructure dependencies

One type of threat consistently identified as a key challenge for critical infrastructure protection (CIP) is that of dependencies and interdependencies among different critical infrastructures (CI). This article draws on a hitherto untapped data source on infrastructure dependencies: a daily maintained database containing over 4500 serious disruption events in different CI all over the world as reported by news media. This article based upon the empirical data set until June 2009 analyses this data to discover patterns in CI failures in Europe like cascading, dependencies, and interdependencies. Some analysis results indicate that fewer sectors than many dependency models suggest drive cascading outages and that interdependencies are hardly reported.
