The information systems of an industrial enterprise are requirements in the field of information security and business continuity. Information infrastructure provides secure data processing and information support of business processes within an industrial enterprise and exchange of information resources with the environment. This study focuses on the modeling of information security infrastructure of industrial enterprises using the apparatus of linear programming to optimize it. It provides a solution to the problem of optimizing protection of information infrastructure of an industrial enterprise in the form of complex mathematical models that include both a model for minimizing the cost of optimizing infrastructure information protection and maximization model quality infrastructure protection information. Sources for this study became years of research materials of its researchers and publications in the public domain.
