Results of a study into the ethnopolitical foundations of security at the levels of society, state, and individual are presented. Based on systemic and institutional approaches, the analysis conceptualizes the essence, content, and specificity of the ethnopolitical dimension of security within the general framework of national security. In contemporary multicultural societies, the ethnic factor is identified as a fundamental determinant of achieving and maintaining high security levels. Security is treated as a multidimensional construct encompassing interrelated physical, economic, social, cultural, and value-normative components requiring coordinated public policy. Key indicators of security and typical threats arising from external challenges and institutional dysfunctions are delineated. Concepts of ethno-security and ethnopolitics are clarified and positioned within the architecture of national security. Practical significance includes principles for preventing ethnic tension, early-warning mechanisms, and criteria for evaluating the effectiveness of governance decisions across administrative levels.
