The Mechanism for Managing the Financial and Economic Security of an Enterprise in the Context of Instability

The development of the information sphere and the corresponding increase in its volume and cost is accompanied by the introduction of advanced information technologies in all spheres of public life of the state, which leads to an increase in the frequency of attacks and potential losses from information leakage. As a result, the complexity of protection systems and an increase in their cost. In these conditions, the task to efficiently distribute limited financial resources to protect the information of business entities becomes more and more important and largely determines the level of financial and economic security of the enterprise and the state as a whole. Of particular relevance is the development of issues of optimization of indicators of the information security system in a dynamic confrontation. Such indicators can be the amount of damage caused from the implementation of information threats, which determines the effectiveness of the protection system, the profit from making investments in information protection, their profitability, and the like. It was established that it is necessary to determine the total amount of protection resources, which minimizes the total losses from possible information leakage in conditions of instability. To determine the optimal strategy for such confrontations Gordon-Loeb model and asymmetric zero-sum game were used. The authors believe that the optimal control mechanism is the distribution of resources between objects that contain a different share of information and are distinguished by natural security, dynamic vulnerability, and the probability of an attack with the allocation of a certain amount of resources. Financial management is a complex system of knowledge about financial relations in the economic process, financial mechanism and technology of financial management of a company. The efficient creation and use of financial resources ensure the financial stability of a company and prevents its bankruptcy. The practical significance of the study lies in determining the optimal moment for the introduction of defense resources - after the direction and intensity of attacks and, accordingly, the possible level of losses was clarified.
