The creation of a system of economic security of the enterprise in the conditions of each enterprise should be accompanied by the awareness of the fact of the need for its development to maintain the ability to respond in a timely manner to changes in the significance of the impact of key threats and to prepare the basis for the most effective use of each new opportunity. The issue of information provision is exacerbated by the exponential increase in information messages, only a limited portion of which is suitable for use in security activities. The purpose of the research is to develop a model of the information support subsystem as an important component of the enterprise's economic security system. In order to form the theoretical basis for the development of the enterprise's economic security system, the following methods were applied: induction and deduction, comparison and systematization – in the study of the essential characteristics of the term "information provision"; synthesis and analysis – to form the content of each component subsystem of the information support system of the enterprise's economic security; morphological analysis – to clarify the nature of changes in the information support system of enterprise management, which will allow to form a subsystem of information support for the implementation of security activities in the conditions of the enterprise; graphic – for visual representation of theoretical and methodical material; abstract-logical – for theoretical generalizations and research conclusions. The construction of the information support subsystem requires the modification of certain parameters of the information support system of enterprise management, based on the tasks that are set before the security subjects. A model has been developed that outlines the purpose and tasks of the information support subsystem, contains functions and principles, and also defines the objects and subjects that are activated within the mechanism of information processing, which involves receiving, checking, supplementing, processing, sending and saving information messages. The practical application of the developed model of the information support subsystem will make it possible to form an information basis for the development of the enterprise's economic security system based on tracking trends in the digital transformation of the economy and the enterprise, as well as the results of security activities.
