Abstract

The article studies the problem of information leakage through the material channel. Such threats can arise as a result of intentional actions of attackers or unintentional leaks associated with the human factor, technical features of information carriers and imperfection of organizational security measures. It is shown that not too many publications are devoted to the study of the material channel of information leakage in the world scientific literature. Existing methods for building effective protection systems should be adapted by determining the permissible parameters of the number of attempts by an attacker to penetrate the object of information activity and the permissible time that can be allocated for such penetration. The article substantiates the theoretical foundations of building a system for protecting information from leakage through the material channel. The author proposes a method for protecting information from leakage through the material channel with specified security parameters, which takes into account the number of permissible penetration attempts and the time that an attacker needs to spend to penetrate the object to seize a technology sample or document. In the developed model, increasing the security parameter of the object leads to a decrease in the probability of penetration. The method is based on determining the line of probability of penetration and allows not only to design effective protection systems, but also to control the penetration process itself by the coincidence or deviation of the security incidents that have occurred from the line of penetration. Modeling such an approach allows you to predict the direction in which the designed process of penetration into the object is going, and to analyze it. It is concluded that further research on the construction of effective information protection systems against leakage through a material channel can be focused on methods for determining the probabilities of penetration and indicators of the security of protection systems, taking into account the characteristics of specific organizations.
