Abstract
At the present stage, the international information and communication network Internet is actively used to host extremist materials. The problem is global in nature and very relevant for the Russian Federation as one of the main participants in the global political process. Using the global Internet and the possibilities of computer communication, ideologists of extremist movements and groups actively influence the consciousness of citizens and, first of all, young people. As a result, the problem of extremism, which can now be regarded as a problem of national importance and a threat to Russia's national security, has been escalating in recent years. The paper describes the essence of extremism as a negative social phenomenon in modern conditions. The role of state law enforcement agencies in combating it. Statistical data of the General Prosecutor's office and the Judicial Department of the Supreme Court of the Russian Federation are presented and analyzed. It is concluded that at present, ensuring national security in the field of information technology, improving the regulatory framework and the development of new technical means to counter the spread of extremist ideas in the information space of Russia are among the priorities for both public authorities and law enforcement agencies.
