The concept of cyber security has become part of the reality of the late 20th and 21st centuries. This term is understood as a system that blocks threats consisting in destroying, changing and unauthorized interception of data. The importance of the cybersecurity problem was emphasized by making legal regulations in the legislation of many countries around the world, including Poland, the United States, Russia and China, and on the basis of the provisions of state associations or international organizations, which is reflected in the relevant regulations of the European Union. The concept of cyber security is multi-faceted, becoming an object of interest not only to countries or organizations, but also to individual individuals living in given communities. The progressive digitization of many areas of life, regardless of the geographical location of the country, means that the need to ensure the proper and safe functioning of this sphere of reality determines the universality of cyber security.
