Method for modeling accuracy measuring in evaluation of sustainability of information structure security system in terms of negative impacts

摘要

The article considers existing simulation methods implemented under the conditions of the ensured uniformity and required accuracy of the results in the evaluation of the stability of functioning of the information structure security system in the conditions of negative influences. The evaluation of the sustainability of an information structure security system in terms of negative impacts is initially based on the development of the information interaction model for the information structures elements relating to the security systems and negative impacts. The authors used a set-theoretic approach allowing not only to describe the characteristics of building elements of the examined structures but also to carry out the process formalization for the security complex functioning models in the form of the construction of discrete (matrix-vector) models with different classifications of threats sets. Assuming the continuity of the time parameters of the functioning process of the information structures' security systems as information systems in terms of negative impacts, it is possible to provide integrated (dynamic) models built with the help of differential equations and describing the state of its elements, which allows, in its turn, assessment of the limits of sustainable management processes occurring during the interaction of these sets.
