The rapid inclusion in the international information space, as well as the accelerated process of informatization, which is one of the characteristic features of modern Ukrainian society, carries both positive and negative trends, which requires the creation of a comprehensive system for ensuring information security, an integral part of which is the administrative- legal regulation of this sphere.
