Development of the laboratory bench for studying intrusion detection systems

The research object of this article is network-based and host-based intrusion detection systems. The aim of the study is to obtain an overview of intrusion detection systems, as well as to build a constructive version of a virtual laboratory bench intended for teaching students (studying the test characteristics of intrusion detection systems). The article provides a brief reference on intrusion detection systems, taking into account the classification by the method of monitoring and the technology of detecting attacks. Today, intrusion detection system is a necessary element of a comprehensive network protection system for both small and large organizations. They improve network security by protecting against external and internal intruders. Therefore, the need to acquire skills in installing, configuring and administering intrusion detection systems is an important part of training information security specialists, which necessitates continuous updating and modernization of training tools. In this paper, we propose a virtual laboratory bench designed to study intrusion detection systems. Its architecture and functioning parameters are described. In order to select an intrusion detection system for a virtual laboratory bench, a comparative analysis of free and commercial intrusion detection systems on the market was carried out. Network-based and host-based intrusion detection systems were considered separately. For both types, their advantages and disadvantages are described. As a result, the functions and operation mechanism are described for the intrusion detection system selected based on the analysis results. In addition, examples of custom rules for handling security events are discussed.
