The article considers the problem of choosing criteria for the task of optimizing resource allocation when implementing an information leakage prevention system in an enterprise. An information leakage prevention system is a software and hardware system designed to detect unauthorized transmission of information. The choice and implementation of an information leakage prevention system in an organization is a time-consuming task that requires an integrated approach and optimal allocation of resources. To obtain the best option for implementing an information leakage prevention system in a particular organization, it is necessary to solve the problem of optimizing the distribution of resources of this organization. The article considers the characteristics of the information leakage prevention system that affect its effectiveness. The boundaries of the optimization problem are determined, the restrictions on the controlled variables are described. As controlled variables for optimization, an economic indicator, human resource, implementation time, structure and technical equipment of the organization were chosen.
