Abstract: The article examines the phenomenon of national security through the prism of the organic theory of state and law. According to the author, national security is a projection of a person's vital needs for self-preservation, self-maintenance and self-reproduction of the multinational people of Russia. The novelty of this statement lies in the expansion of the traditional approach to the concept of security by the needs of self-maintenance and self-reproduction. The object of ensuring national security is the multinational people of the Russian Federation, which currently exists in the form of an individual, society and the state, in the past as a national history, culture, values, in the future - as a steadily developing independent subject of international relations. The main role of the national security is to find an optimal compromise between the interests of ensuring the security of the currently existing individuals, society and the state for the purpose of self-preservation, self-maintenance and self-reproduction of the multinational people of the Russian Federation in the past, present and future. The multinational people of the Russian Federation were formed as a result of the cultural and biological evolution of people with an optimal balance of altruistic and selfish behavior. Preserving and multiplying the population of people with these innate and acquired properties, as well as maintaining proportions between population groups with different ideological attitudes to perform a wide range of tasks is one of the first tasks of ensuring national security, normatively expressed as saving the people of the Russian Federation. The emergence of the institute of national security in law is connected with the need to harmonize the legal virtuality created over the past 30 years with human nature and objective geopolitical reality. The appeal to the institute of national security will lead to the creation of a national order, as enshrined in law, perceived by all and implemented in the present optimal algorithm of behavior of the individual, society and the state, ensuring the preservation of the past and sustainable development in the future of the multinational people of the Russian Federation.
