Most books on cybercrime are written by national security or political experts, and rarely propose an integrated and comprehensive approach to cybercrime, cyber-terrorism, cyber-war and cyber-security. This work develops approaches to crucial cyber-security issues that are non-political, non-partisan, and non-governmental. It informs readers through high-level summaries and the presentation of a consistent approach to several cyber-risk related domains, both from a civilian and a military perspective. Explaining fundamental principles in an interdisciplinary manner, it sheds light on the societal, economic, political, military, and technical issues related to the use and misuse of information and communication technologies.
