Russia today is a dynamically developing state that, despite external pressure, continues to strengthen its positions in the world arena, timely preventing external and internal threats to economic security. Social stability is a fundamental prerequisite for the dynamic development of the state. In this regard, the state's task is to prevent destructive processes in social and economic development, using a set of measures and management procedures. The state of the social sphere, trends and forecasts of its formation have always been in the focus of the interests of the leadership of our country, government organizations and the scientific community. This is because the social sphere is of primary importance for the development of society in particular and the state as a whole. In recent years, large-scale changes have begun to take place in the Russian Federation, including the development of new public legislation, the implementation of targeted projects, the formation of a new concept of public protection of the population, and many actions have been taken to provide a decent level of well-being and increase the quality of life of the Russian people. Despite the fact that the Russian government has made great efforts to reduce the scale of unemployment and poverty, improving the quality of life, the social problem remains quite acute. The main factor was the sudden change in the international situation in the last few years, the introduction of financial and restrictive sanctions, the implementation of hostile political activities by certain foreign states against Russia, and as a result, the complication of the social and financial situation within our state. However, successful social and financial development remains the highest value for the Russian state in the near future. The purpose of this activity is to identify the relevance and complexity of problems of economic security and assess indicators that determine threats to security in the public sphere. Observation and diagnosis of the degree of threats to the national interests of the state on the basis of indicators of socio-economic development indicators in the public domain is a priority task in the existing realities of our life. Modeling the threats to economic security, ie, obtaining specific values of economic security indicators depending on their belonging to a particular risk class (level), it is possible to develop an appropriate plan of measures to improve economic security in the social sphere on the basis of the proposed classification. Monitoring and diagnosing the level of threats to the national interests of the country on the basis of indicators of social and economic development in the social sphere is a paramount task in the existing realities of our life. At the same time, the results obtained serve as a good basis for developing development strategies for the future with the preservation of social stability. The aim of the study is to formulate methodological provisions for the development of the theory of economic security based on the definition of threats to the economic security of the social sphere, using the proposed model of the relationship between the key factors that affect the level of security in this area. The research uses a set of general scientific approaches (abstract-logical, deductive, complex and systemic). The realization of the research process was carried out with the help of the dialectical method of cognition, which predetermines the study of economic phenomena in their interconnection and development. To solve individual problems, economic-statistical methods, comparison methods, absolute, relative and average values, graphical and tabular data representation, correlation-regression analysis, Ward clustering were used.
