This book combines game theory and complex networks to examine
intentional technological risk through modeling. As information security
risks are in constant evolution, the methodologies and tools to manage
them must evolve to an ever-changing environment. A formal global
methodology is explained in this book, which is able to analyze risks in
cyber security based on complex network models and ideas extracted from
the Nash equilibrium. A risk management methodology for IT critical
infrastructures is introduced which provides guidance and analysis on
decision making models and real situations. This model manages the risk
of succumbing to a digital attack and assesses an attack from the
following three variables: income obtained, expense needed to carry out
an attack, and the potential consequences for an attack. Graduate
students and researchers interested in cyber security, complex network
applications and intentional risk will find this book useful as it is
filled with a number of models, methodologies and innovative examples.
