Abstract: The article is devoted to the urgent problem of ensuring the security of heterogeneous information platforms using a multi-agent threat detection system. The object of the study is a multi-agent platform. The authors pay special attention to such aspects of the topic as: security of multi-agent platforms, management of threat detection agents, interconnection between different threat detection agents, vulnerability in multi-agent platforms. Trends are being considered for the development of new distributed security models. The paper presents a multi-agent architecture for security services, as well as a general scenario for deploying security in multi-agent threat detection systems. The paper presents a multi-agent architecture for security services, as well as a general scenario for deploying security in multi-agent threat detection systems. Using a multi-agent system approach to a security model that provides control from the sender using the mobility and extensibility characteristics of the agent. The multi-agent protection system model for heterogeneous information platforms provides an improved approach for online communications, providing flexible mechanisms for the comprehensive protection of heterogeneous information platforms that can satisfy various security requirements and provide better control over the data to its sender.

Abstract: The work is devoted to the urgent problem of ensuring the security of heterogeneous information platforms, using the system of electronic support of on-line communications processes in a medical institution - e-health online communications. The authors pay special attention to such important aspects of the topic as: the security of heterogeneous information platforms, the model for the protection of heterogeneous information platforms, the classification of communications and the protection mechanisms of MMK. The tendencies for the development of new distributed safety models are considered. This article presents a model of multi-level communications. A classification of communications and protection mechanisms for each level with different security levels using cryptography protocols is proposed. Security flexibility can be provided to health organizations using a variety of key size combinations to protect data and channels. At each level, different levels of security can be provided depending on the sensitivity of the data. Thus, we came to the MMK model as a solution to the problem of communication in e-health and other large organizations with a distributed network of computer communications.

Abstract: This work presents the analysis of the modern approaches towards development of comprehensive systems for protecting heterogeneous information platforms. Despite the advantages of the reviewed approaches, majority of them are aimed at solving a particular task, rather than a complex solution to the problem of protection of information in the environment of sophisticated heterogeneous systems. This article demonstrates the architecture of a heterogeneous information system acting as an object of protection. The result of the conducted research lies in the formation of a concept of creation of an Information Security System, the architecture of which is built upon a multi-agent approach and is oriented towards heterogeneous information systems. The author proposes a model for a comprehensive protection of the heterogeneous information platforms and examines the methodology for intelligent threat detection. The results of this research suggest increasing the area of use of the multi-agent approach and its integration into the intelligent analysis of development and functionality of the information systems.
