Cyber Operations and the Use of Force in International Law

The internet has changed the rules of many industries, and war is no exception. But can a computer virus be classed as an act of war? Does a Denial of Service attack count as an armed attack? And does a state have a right to self-defence when cyber attacked? With the range and sophistication of cyber attacks against states showing a dramatic increase in recent times, this book investigates the traditional concepts of 'use of force', 'armed attack', and 'armed conflict' and asks whether existing laws created for analogue technologies can be applied to new digital developments. The book provides a comprehensive analysis of primary documents and surrounding literature, to investigate whether and how existing rules on the use of force in international law apply to a relatively new phenomenon such as cyberspace operations. It assesses the rules of jus ad bellum and jus in bello, whether based on treaty or custom, and analyses why each rule applies or does not apply to cyber operations. Those rules which can be seen to apply are then discussed in the context of each specific type of cyber operation. The book addresses the key questions of whether a cyber operation amounts to the use of force and, if so, whether the victim state can exercise its right of self-defence; whether cyber operations trigger the application of international humanitarian law when they are not accompanied by traditional hostilities; what rules must be followed in the conduct of cyber hostilities; how neutrality is affected by cyber operations; whether those conducting cyber operations are combatants, civilians, or civilians taking direct part in hostilities. The book is essential reading for everyone wanting a better understanding of how international law regulates cyber combat.

Neutrality in Contemporary International Law

The law of neutrality - the corpus of legal rules regulating the relationship between belligerents and States taking no part in hostilities - assumed its modern form in a world in which the waging of war was unconstrained. The neutral State enjoyed territorial inviolability to the extent that it adhered to the obligations attaching to its neutral status and thus the law of neutrality provided spatial parameters for the conduct of hostilities. Yet the basis on which the law of neutrality developed - the extra-legal character of war - no longer exists. Does the law of neutrality continue to survive in the modern era? If so, how has it been modified by the profound changes in the law on the use of force and the law of armed conflict? This book argues that neutrality endures as a key concept of the law of armed conflict. The interaction between belligerent and nonbelligerent States continues to require legal regulation, as demonstrated by a number of recent conflicts, including the Iraq War of 2003 and the Mavi Marmara incident of 2010. By detailing the rights and duties of neutral states and demonstrating how the rules of neutrality continue to apply in modern day conflicts, this restatement of law of neutrality will be a useful guide to legal academics working on the law of armed conflict, the law on the use of force, and the history of international law, as well as for government and military lawyers seeking comprehensive guidance in this difficult area of the law.
