Formalized methodology for building a model of a secure information system

The article considers the problem of building a secure information system provided that it is affected by potentially possible destructive factors of a man-made and man-made nature. In order to solve practical problems of engineering design, a formalized model is proposed, built on the basis of application of mathematical apparatus of algebra of multidimensional matrices. The article describes the formalized method of building a model of a secure information system and provides an example of its use for solving a specific problem.
