**Abstract**

The objective of the research is considering the international information security concept that has developed at the global and regional levels and analysis of legal instruments for its implementation and resolving problems of the regulation of relations in the global information society. A complex of general scientific and philosophical methods including the formal-logical, comparative-legal, formal-legal, systemic-structural, and problematic-theoretical methods, as well as methods of analysis and synthesis, generalization and description, and comparison, was used in the research. As a result of the research, it has been found that a unified concept of provision of the international information security has developed at the global and regional levels, which needs legal instruments for its implementation at the global level. In the drafting and acceptance of international treaties at the global level, the experience of the Council of Europe in prosecution of cybercrime and protection of privacy should be used. The findings can be used in the activities of international organizations in execution of their functions of unification and harmonization of the international information security law and by the national telecommunication operators in the process of entering international and foreign markets.
