The history of intercourse of states, nations, alliances of countries their associations dates back several thousand years. Such relationships sequentially fulfill several stages, such as cooperation, integration, competition and confrontation. It should be noted that the listed stages unite many areas - political, military, economic, technological, social and ideological. Interaction and confrontation are carried out at different levels - global, strategic, tactical and individual. In this article, the main attention is paid to the stage of confrontation in a relatively new, insufficiently explored field of activity - the domain of cyberspace. The importance of this topic is determined by the desire of each state to ensure the protection of national interests in terms of cybersecurity. It is worth to note the difference between the cyberspace domain and other domains as it stated. First of all, cyberspace is man-made. Secondly, military and civilian (diplomatic, trade, etc.) capabilities in other domains are managed with the help of and through the cyber domain. Third, the military and civilian aspects of cyber operations are difficult and sometimes impossible to distinguish because they are tightly intertwined. Fourth, it is very difficult to establish the attribution of operations in cyberspace. Absence of such indicators (or measurement units) as mass, gravity, friction or distance is yet another feature of cyberspace. In addition, the following statements have become widespread: cyberspace is an abstract space; cyberspace has no natural boundaries; cyberspace can obtain any number of subspaces (eg Internet, telephone system, radio communication system); cyberspace is not limited in its dimensions (for example, the Internet has an IP address, MAC address, port number, etc.); each dimension of cyberspace has no limits; each cyber object has its own coordinates; one cyber object can belong to more than one subspace; objects in cyberspace can interact with objects in physical space.
