Cyberspace determinants of the decision-making process

In today's world, information is an indispensable component of every human activity. Its significance is especially appreciated in various state security systems, the effectiveness of which depends, inter alia, on the decision-makers' skills in solving decision-making problems, as well as the quantity and quality of information held. The functioning of man in the information society made the gathering, storage and use of information a part of everyday life and, at the same time, an integral activity of social life.
This state of affairs has resulted in the popularization of the practical use of information technology, which creates perfect conditions for communication in the broadly understood cyberspace environment. In its area, new forms of social relations, cooperation, and threats have been developed, which determine the decision-making process. These days have become dominated by the increasing demand for information. The problem of its protection against unwanted obtaining (disclosure) has become a challenge for many scientific communities. This state of affairs has forced us to take a num-ber of steps to ensure the security of useful information, characterized by accuracy, unambiguity, completeness and authenticity. A particular need for information understood in this way is observed while solving complex decision problems (difficult to predict or with a structure that has not been seen so far). Therefore, the question arises: What methods can be used, of which the implementation would help to solve decision-making problems in the period of information deficit?
