The article proposes to determine the effectiveness of the use of information technologies in the interests of economic security using stochastic modeling. To evaluate the accuracy of a model means to find the discrepancy between the results obtained after the implementation of this model with the actual results. It is quite clear that the quality of each of the stages affects the final accuracy of the model. Life of the population, the development of a system of international economic dependence. The combination of these problems and the algorithm for their solution are closely related to the category of “security”, which in Greek means “to own the situation.“ Changes in internal and external factors in the development of the national economy actualize the study of the issue of ensuring the economic security of the state. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
