Introduction. In the modern humanitarian science, there is no unanimity in understanding the essence of national security and the main object it is to ensure due to detachment of the modern jurisprudence from the genuine nature and innate capabilities of a human being. The modern geopolitical confrontation clearly shows the constraints of the existing approaches, which consider the national security as a simple aggregate of a person’s, society’s and the state’s security at the present time, whereas the contemporary hybrid wars are first of all aimed at destroying the enemy’s past and programming its future. Therefore, the task to elucidate the relevant subject matter of the national security relations has become an urgent issue for further successful survival of the multinational people of Russia and preservation of the checks and balances principle existing in the world. The aim of the study is to determine the relevant subject and object of ensuring the national security of the Russian Federation.Materials and Methods. The result of the analysis of more than 1000 files containing scientific, methodological, regulatory and educational materials regarding the national security as a legal category has become the material for the present research. The multifacetedness of the studied legal phenomena has induced the application of the interdisciplinary approach and reference to the data obtained by the representatives of anthropological, theological, philosophical and historical legal sciences. The diagrams and categories of the theories of the legal order of society, institutional changes, the geopolitical and security theories have been used as the specific scientific methods. The method of dialectical scientific knowledge, the social systems, management and gaming theories methods were widely used enabling considering the behavior of the security ensuring process participants from the pragmatic perspective.Results. Today’s Russia, as a moment of being of the multinational people of the Russian Federation in the current spatial-temporal reality, is the sovereign unity of the Russian person, society and state formed for collective survival, provision of protection and safety through availability of the necessary forces and facilities, single national order and worldview, along with the single will embodied in the presidential power. “The national security of the Russian Federation” is the result of assessment and maintenance of such beingness of the multinational people of the Russian Federation by means of the citizens’, society’s and state’s forces and facilities, that satisfies in the sovereign and independent way its vital needs for self-preservation, self-renewal and self-reproduction in the past, present and future. By introducing a relevant object of ensuring the national security and by changing the nature of relationships between the subjects, the proposed definition creates the doctrinal basis for transition to a collective model of survival in the present geopolitical situation.Discussion and Conclusions. The essence of the notion “national” in the context of the “National Security Strategy” is manifested as a single state form, comprising the existence and beingness of the Russian state, society and personality in the frame of their genesis and evolvement in the past, present and future in the geopolitical philosophical dimension. This corresponds to the notion "civilization" as a social form of the motion of matter, providing its stability and ability to self-development through self-regulation and exchange with the environment. The multinational people of the Russian Federation as a civilization or a “thousand-year-old state” possesses the real sovereignty, its own national order and worldview; it had never lost its statehood, was able to survive all the fatal threats to its secure existence. In our opinion, in the current spatial-temporal reality, an efficient subject of security, which is at the same time the main object of ensuring security and the only form of collective survival for a person, is the multinational people of the Russian Federation as a nation united by the state form and governed by it. Motherland as a pathetic designation of the Russian civilization, legislatively defined by the Russian Constitution as “the multinational people of the Russian Federation”, is a relevant form of collective survival for the Russian person, personality, society and the state.
