Information Warfare as International Coercion: Elements of a Legal Framework Christopher C. Joyner * and Catherine Lotrionte ** Full text available: PDF format *** Abstract Worldwide interconnectivity through massive computer networks now makes states vulnerable to new threats. Foreign governments can launch computer-based assaults, or acts of information warfare, on another state's domestic systems such as energy grids, telecommunications, and financial facilities that could severely damage or disrupt national defence or vital social services. Even realizing the new forms of computer-generated weapons and changing concepts of sovereignty and territory brought about by global interdependence, international law is likely to rely on UN Charter principles to define the legal boundaries of cyberspace. While perhaps not armed force literally, resort to cyberforce may be viewed as a form of intervention that can produce harmful or coercive effects, and put at risk the national security of another state. There is need for modern international law to define more precisely the criteria used to distinguish which state actions are permissible as normal computer-generated transborder data flow from those cyberactivities that might qualify as an `armed attack' against a state. Clearer rules are also needed for what responses are permissible as self-defence by a state targeted in an information warfare situation and how international institutions might facilitate the attainment of these objectives. * Professor of International Law, Department of Government, Georgetown University. ** Assistant General Counsel, Office of the General Counsel, Central Intelligence Agency; Adjunct Professor, National Security Studies Program, Georgetown University.
