The advent of cyberspace has led to a dramatic increase in state-sponsored political and economic espionage. This monograph argues that these practices represent a threat to the maintenance of international peace and security and assesses the extent to which international law regulates this conduct. The traditional view among international legal scholars is that, in the absence of direct and specific international law on the topic of espionage, cyber espionage constitutes an extra-legal activity that is unconstrained by international law. This monograph challenges that assumption and reveals that there are general principles of international law as well as specialised international legal regimes that indirectly regulate cyber espionage. In terms of general principles of international law, this monograph explores how the rules of territorial sovereignty, non-intervention and the non-use of force apply to cyber espionage. In relation to specialised regimes, this monograph investigates the role of diplomatic and consular law, international human rights law and the law of the World Trade Organization in addressing cyber espionage. This monograph also examines whether developments in customary international law have carved out espionage exceptions to those international legal rules that otherwise prohibit cyber espionage as well as considering whether the doctrines of self-defence and necessity can be invoked to justify cyber espionage. Notwithstanding the applicability of international law, this monograph concludes that policymakers should nevertheless devise an international law of espionage which, as lex specialis, contains rules that are specifically designed to confront the growing threat posed by cyber espionage.

This book examines how espionage and its applications have changed since World War II and how domestic, regional, and international legal mechanisms can provide an effective legal solution to this change affecting the economic well-being of individuals, companies, and states.

This compact, highly engaging book examines the international legal regulation of both the conduct of States among themselves and conduct towards individuals, in relation to the use of cyberspace. Chapters introduce the perspectives of various stakeholders and the challenges for international law. The author discusses State responsibility and key cyberspace rights issues, and takes a detailed look at cyber warfare, espionage, crime and terrorism. The work also covers the situation of non-State actors and quasi-State actors (such as IS, or ISIS, or ISIL) and concludes with a consideration of future prospects for the international law of cyberspace. Readers may explore international rules in the areas of jurisdiction of States in cyberspace, responsibility of States for cyber activities, human rights in the cyber world, permissible responses to cyber attacks, and more. Other topics addressed include the rules of engagement in cyber warfare, suppression of cyber crimes, permissible limits of cyber espionage, and suppression of cyber-related terrorism. Chapters feature explanations of case law from various jurisdictions, against the background of real-life cyber-related incidents across the globe. Written by an internationally recognized practitioner in the field, the book objectively guides readers through on-going debates on cyber-related issues against the background of international law. This book is very accessibly written and is an enlightening read. It will appeal to a wide audience, from international lawyers to students of international law, military strategists, law enforcement officers, policy makers and the lay person.

This revised and expanded edition of the Research Handbook on International Law and Cyberspace brings together leading scholars and practitioners to examine how international legal rules, concepts and principles apply to cyberspace and the activities occurring within it. In doing so, contributors highlight the difficulties in applying international law to cyberspace, assess the regulatory efficacy of these rules and, where necessary, suggest adjustments and revisions.

The result of a three-year project, this manual addresses the entire spectrum of international legal issues raised by cyber warfare.

This book offers a comprehensive overview of the international law applicable to cyber operations. It is grounded in international law, but is also of interest for non-legal researchers, notably in political science and computer science. Outside academia, it will appeal to legal advisors, policymakers, and military organisations.

Tallinn Manual 2.0 expands on the highly influential first edition by extending its coverage of the international law governing cyber operations to peacetime legal regimes. The product of a three-year follow-on project by a new group of twenty renowned international law experts, it addresses such topics as sovereignty, state responsibility, human rights, and the law of air, space, and the sea. Tallinn Manual 2.0 identifies 154 'black letter' rules governing cyber operations and provides extensive commentary on each rule. Although Tallinn Manual 2.0 represents the views of the experts in their personal capacity, the project benefitted from the unofficial input of many states and over fifty peer reviewers.
