The semantic uncertainties between the basic concepts in the field of cybersecurity significantly narrow the range and reduce the effectiveness of scientific research on methods of analysis and forecasting, for example, APT cyberattacks or the development of security complexes based on formal models of proof their effectiveness. The direction of the possible overcoming of the problem is the development of a conceptual model of cyberspace and cybersecurity, which reduces the level of possible uncertainties in describing various complex situations in cyberspace due to the use of special tools terminology, graphics, and mathematical formalization. The beginning of the research - the selected statement: the physical basis of cyberspace are information and telecommunication systems (ITS). The analysis of the information processes of such systems was carried out on the basis of the attributive-transfer approach to the essence of information. It defines “information” how to get the properties (attributes) of the object, reflecting the properties of another object. Electronic devices and physical environments for signal transmission constitute the technological basis of the ITS. Discrete electronic and electromagnetic signals circulating between electronic devices allow the formation of information, transform it and transmit it in space at different distances. Through various sets of electronic devices and signals in the ITS, various information processing technologies are implemented. They provide ITS users with various information services. Users of ITS can be people or technical systems (devices). According to the results of the analysis, a conceptual model of cyberspace and cybersecurity has been developed. The model consists of: 1) a set of interconnected basic terms that reflect the essence of information processes in the ITS. Due to these terms, synthesized definitions for the terms “cyberspace” and “cybersecurity”; 2) graphic model of cyberspace, which explains the ratio of its components; 3) mathematical model of cyberspace is a collection of mathematical constructions based on the theory of sets that specify the nature of the relationship between components of cyberspace. Cyberspace models have developed mathematical cybersecurity criteria for the cyberspace segment. The model also makes it possible to significantly simplify the process of analyzing APT attacks or complex security processes in cyberspace.
