Justification of the Rational Composition of the Information Security System

Abstract

This paper examines a methodological approach to the construction of models and algorithms for supporting decision-making in substantiating rational composition of the information security system of a corporate computer network. In this case, the problem under consideration is presented in the form of a discrete model of mathematical programming. A special feature of the model is the ability to take into account a wide variety of destructive impacts on a computer network and methods of protecting it. The generality of the model is also ensured by taking into account the possible nonlinear nature of the function reflecting the specific goals of creating an information security system. To solve the problem, a generalized algorithm is developed that takes into account the features of the model. The general nature of the requirements for the parameters of the model and algorithm allows, on their basis, to form a fairly wide range of methods for supporting decision-making in the substantiation of the rational composition of the information security system for specific variants of corporate computer networks and the conditions of their operation.
