The thesis "Social Protection of the Population in the System of Economic Security of Ukraine" deepens the theoretical foundations and develops scientific and practical recommendations for the innovative transformation of social protection of the population, the mechanism of its regulation in order to achieve economic security of Ukraine. The paper substantiates a scientific approach to the development and implementation of strategic directions for reforming the social protection sector in Ukraine, including a list of components that include: purpose, goals, objectives, principles, subjects and objects, tools and resources, requirements, strategic indicators, sequence of actions and focus on the introduction of innovations based on digital and information technologies within the development of an integrated social protection platform, a single digital social protection platform, a single information space for social protection of the population. The definition of the essence of the principles and problematic aspects of state policy in the field of social protection of the population is developed. The approaches to defining and evaluating the mechanisms of interaction between the social protection of the population and the economic security system of Ukraine are revealed. A scientific and methodological approach to diagnosing the development of social protection of the population as a component of economic security of Ukraine is proposed. The directions of reforming the social protection of the population to strengthen the economic security of Ukraine are substantiated, based on the implementation of foreign experience of economically developed countries, countries with transition (transitional) economies, developing countries and taking into account the limitations on the application of foreign experience for the country. The classification of key risks, hazards and threats to the economic security system of the state has been further developed. The positive and negative aspects of the social protection sector, as well as the positive and negative aspects of the impact of social protection on economic security are identified. Approaches to assessing the functioning of the social protection sector of Ukraine in the context of interaction between the SS and the economic security of the State are formed. The content of social protection of the population as the main component of measures to prevent and facilitate the solution of social problems and provide conditions for improving the quality of life of the country's population is disclosed. The connection between the SPP and the economic security of the country is determined. It is proved that within the framework of historical development there have been changes in the relationship and mutual influence between social protection and economic systems of different levels. The current direct and indirect impact of social protection on economic growth at the macro-, meso-, and micro-levels is determined. The features of four global approaches that form the link between social protection and economic development (SRM, SRP, TSP, CCT) are revealed. The scheme of the relationship between social protection and the economy at different levels of their functioning (global, international, national) is presented. The author decomposes the systems of national and economic security of the country and, based on the analysis of primary sources, defines the essence of the terms "economic security", "economic security of the State", "system of economic security of the State". The peculiarities of ensuring the totality of the country's national interests through the system of economic security of the State are revealed. A theoretical characterization of the economic security system of the State is provided, which reveals the purpose, tasks, conditions, subjects, objects, levels, functions, principles, indicators (indicators) of the SES. The author provides an interpretation and defines the essence of the terms "risk", "danger", "threat", and also identifies the relationship between risks, dangers and threats. A set of key risks, hazards and threats to the DBMS is formed. The components of the state economic security system are identified and characterized. The connection between social policy, social protection, social security, development of the country's economic system, national economic policy and the system of economic security of the state is revealed. The mechanisms of interaction between the sphere of social protection of the population and the system of economic security of Ukraine are determined, and a comparative assessment of the identified mechanisms is carried out. Based on the analysis, the author substantiates the characteristics of the social protection sphere in Ukraine (positive and negative aspects) and its impact (positive and negative) on the economic security of the State. The study of the institutional and legal framework for the interaction between soc
