The problem of economic security continues to remain relevant today, since the unstable, rapidly changing social and economic situation does not allow hoping for a quick solution to the institutional and infrastructural aspects of the development of economic systems. An important place in this issue is occupied by theoretical and methodological principles of ensuring economic security, the degree of development of which is still far from satisfactory. A review of regulatory documents and scientific papers on the principles of ensuring economic security indicates the dominance of the legislative and doctrinal approach. At the same time, systemic, process, situational approaches to the problem of economic security and the principles of its provision remain poorly studied and insufficiently developed. The purpose of the study is to substantiate the development feasibility of additional methodological tools, the core of which can be system, process, situational approaches, and the underlying principles along with the widespread legislative and doctrinal approach in the field of ensuring economic security. The proposed methodology based on systemic, process and situational approaches is based on principles that have proven themselves well in various branches of science. These principles are especially widespread in the theory and practice of both public administration and corporate management. The article proposes the principles of ensuring economic security, including the principle of increasing and orchestrated efforts, the principle of balance, and the principle of cyclical development, which can be useful in developing methodological measures defined in the Economic Security Strategy of the Russian Federation for the period till 2030.
