The article analyses contemporary legal aspects and current cybersecurity issues, cybercrime features of Rus- sian and foreign law of information and communication technologies. The research methods consist of comparative legal analysis of contemporary Russian and foreign legislation and law enforcement practice, as well as, a formal and logical study of a conceptual apparatus, content and struc- ture of the research object. The study results enable the authors to formulate the awareness of cybercrime legal content, that includes not only offenses committed by using computer technology, but other information and communication equipment and tools, including software either. The rapid spread of cybercrime, the emergence of new forms of organized crime using the global Internet, intended and well-organized cyber attacks on a critical infrastructure of states and private companies indicate the formation of a special area of crime - cybersecurity crime and information technol- ogy, which goes beyond a common insight of crime of information technology and communications. Therefore, the authors came to certain conclusions to conceptualize theoretical and methodological principles, develop the foundations of law and order of cybersecurity, clarify the conceptual apparatus and specifics of legal regulation of cybersecurity in public and private law, as well as the formation of a new line of criminology of cybercrime. The scientific novelty of the study consists of a conceptual justification of a cybercrime countering, as an ele- ment of national cybersecurity, as well as, the substantiation of a specific line of criminology - cybercriminology.
