Model of analysis of sustainable management of information security of a distributed information system

Abstract

The article presents a model of stability analysis of a distributed information system in the sense of sustainable provision of its information security with some means of protection. It is assumed that the information system in question is operating in real time. On the basis of the proposed model, the area of functional security of a distributed information system under the influence of information attacks of the enemy is constructed, while this task is solved from the condition of specified allowed intervals: the probability of ensuring the information security of the system under consideration, as well as the criterion of deterioration of the main indicator of its effectiveness from enemy interference in process of its functioning. In the form of a strict sequence of actions, an algorithm is formulated to implement the proposed model in practice, provided that the information security of a distributed information system is managed reliably.
