Risk and Interdependencies in Critical Infrastructures, 2012
A Guideline for Analysis
Springer Series in Reliability Engineering Series

Today?s society is completely dependent on critical networks such as  water supply, sewage, electricity, ICT and transportation. Risk and vulnerability analyses are needed to grasp the impact of threats and hazards. However, these become quite complex as there are strong interdependencies both within and between infrastructure systems. Risk and Interdependencies in Critical Infrastructures: A  guideline for analysis provides methods for analyzing risks and interdependencies of critical infrastructures.

 A number of analysis approaches are described and are adapted to each of these infrastructures. Various approaches are also revised, and all are supported by several examples and illustrations. Particular emphasis is given to the analysis of various interdependencies that often exist between the infrastructures.

 Risk and Interdependencies in Critical Infrastructures: A  guideline for analysis provides a good tool to identify the hazards that are threatening your infrastructures, and will enhance the understanding on how these threats can propagate throughout the system and also affect other infrastructures, thereby identifying useful risk reducing measures. It is essential reading  for municipalities and infrastructure owners  that are obliged to know about and prepare for the risks and vulnerabilities of the critical infrastructures for which they are responsible.
