Abstract: The relevance of the topic under consideration is due to the globalization of the information space, which arises in connection with the intensive development of information technologies, which implies the need to develop new approaches to ensuring information security. Based on the principles of sovereign equality and international cooperation, States interact with each other in the common interest (including in the legal field), develop basic principles and norms on which the legal foundation for the legal provision of international information security is based. The author states that the importance of implementing coordinated measures by participants in international legal interaction in this area is due to the fact that if information security is an integral part of national security, then international information security is an immanent element of international security, without which it is impossible to build a system of secure interstate cooperation in modern realities. The author applied the method of theoretical analysis in the process of research, the conclusions are based on a formally logical method. The main conclusion of the author of the study is the following position: the goals of maintaining the state of security of the global information space may be unattainable without proper cooperation (in particular, organizational and legal in nature) in solving problems related to ensuring international information security at several levels of interaction: bilateral, regional, global. The high level of interdependence of countries and the need to ensure the principle of indivisibility of security form the global need to find compromises and common approaches in ensuring international information security. The definition of a single conceptual framework that does not allow ambiguity, contradictions and terminological uncertainty, as well as the basic principles that are the legal foundation of the legal regulation of international information security, should be implemented by developing a single international treaty. This conclusion is due to the ineffectiveness of the norms of "soft law" and international morality based on the principles of voluntary fulfillment of obligations implemented in the process of interstate interaction.
