This thesis conducted a theoretical generalization of the development and establishment of the concept of "economic and financial security", "financial controlling" classification of approaches according to Ukrainian and foreign researches is done. Functional principles of financial controlling in the system of economic security, and its component - financial security - are revealed. Approaches to the principles of forming the systems of financial controlling and economic security are characterized. The theoretical basis for calculating the level of economic indicators of state security is added by the indicators of relation between currency-gold reserves and volume of GDP, and ratio the ratio of funds from debt service to exports. Trends of indicators of economic security with emphasis on criteria of financial security are settled. The results obtained in terms of financial security are compared to a threshold value, and, based on the forecasts, characteristics of the dynamics of key macroeconomic indicators are submitted, indicating the existence of threats to each of them. The preconditions of the shadow economy of Ukraine are outlined as one of the biggest threats to economic security and stable national development. The author's approach to determining criteria and interrelationships of threats to economic security and quality of life as a key component of national interests is given. Using forecasting models (Hoerl model, regression prediction) there was calculated the effectiveness of macroeconomic fundamentals on the economic security and sustainable development, the results of which indicate deterioration of the quality of life during 2011-2013, in contrast to official data, due to existing threats to the financial sector and economic security in general. Among the strategic decisions of counteracting shadow economy the introduction of the following measures were offered: determination of the dependence of illegalization dynamics on the changing external and internal factors, studying legal and regulatory framework and means of combating illegal activities for deficiencies in the national legislation, and testing management decisions in regulatory policy on the probability of increased risk of illegalization and attracting financial controlling elements. Experience in implementing measures against illegal economy was analyzed, and on their basis the application of principles of financial controlling in minimizing the shadow sector of the Ukrainian economy was worked out. The functions of currency control through cooperation of the National Bank, State Customs Service, Ministry of Finance and other executive bodies within the frames of strengthening financial security and currency regulation were emphasized. As financial controlling measures - regulatory monitoring of inflow and outflow of capital, the analysis of trends in raising funds and loans, management of distribution and redistribution, analysis of investment proposals, are introduced to be used in the system against illegal economy. Measures on minimizing, eliminating and preventing threats to economic security of the state through the use of financial controlling tools are designed. In particular, mechanisms of financial controlling in the process of ensuring security and improving financial system's state control over economic development and financial processes are proposed Key words: financial controlling, economic security of the state, shadow economy, the criteria for financial security.
