INFORMATION PROTECTION FROM LEAKAGE THROUGH TECHNICAL CHANNELS ON THE BASIS OF ADAPTIVE MULTIAGENT SECURITY SYSTEM AT THE INFORMATIZATION OBJECT

Abstract

Purpose: to show the creation and consideration perspective of the ways to build a multi-agent information security system at an informatization object with the implementation of a decentralized and mixed (centralizeddecentralized) principle of its design and functioning in order to exclude the extraction of various types of information, data about the characteristics of the informatization object and relationships between its structural elements. Method: the method of functional and structural analysis of technical channels of leaking information circulating in the form of speech information at the informatization objects of the internal affairs bodies in the course of their daily activities or during official activities, as well as ways to build an information security system from leakage through technical channels is applied. Result: the factors determined are those that are necessary to be taken into account when substantiating the composition and functions of agents of a multi-agent information security system, depending on the conditions characterizing the dynamics of the intruder’s actions to obtain protected information, the dynamics of the application of measures and means of protection. It is shown that a multi-agent protection system composition can include two classes of agents - simple and intelligent, and the system itself must be a multilayer structure, each layer of which is tied to a certain type of technical information leakage channels, and contain one or more agents (meta-agents), which provide solution of decision support tasks for information protection in each layer and in the security system as a whole and control of other agents. Examples of the composition and structure of a multi-agent system for protecting against leakage through technical channels, as well as examples of the structure of a simple and intelligent agent for such a system are given. The scientific novelty of the article is in the fact that the idea of creating a multi-agent system is considered for the first time in relation to solving the problem of protecting information from leakage through technical channels, the composition, structure and functions of such systems are determined, as well as the directions for the development of methodological support for their creation and operation.
