摘要：In the past two decades, cyber-space became the new, “fifth battlefield” in the field of international relations. Decision-makers and scholars agree that the major threat to national security of every state today is cyber-war, cyber-terror and cyber-crime. This is due to the lack of inter-state institutional and legal framework for cyber-space. Thus, the inter-state relations in cyber-space is one of classical Hobbesian anarchy. This article examines: 1. the essence and nature of cyber-space and its relation to international society, in the context of world technological domination that makes anarchy possible; 2. the main aspects of anarchy in cyber-space during the past two decades; 3. the possibility of institutionalization of international legal system (through multilateral treaty) in cyber-space, from the perspective of three distinct IR theoretical traditions: Hobbesian, rationalist and Kantian/moral.
