The information revolution has transformed both modern societies and the way in which they conduct warfare. Cyberwar and the Laws of War analyses the status of computer network attacks in international law and examines their treatment under the laws of armed conflict. The first part of the book deals with the resort to force by states and discusses the threshold issues of force and armed attack by examining the permitted responses against such attacks. The second part offers a comprehensive analysis of the applicability of international humanitarian law to computer network attacks. By examining the legal framework regulating these attacks, Heather Harrison Dinniss addresses the issues associated with this method of attack in terms of the current law and explores the underlying debates which are shaping the modern laws applicable in armed conflict.
