INTRUSION DETECTION SYSTEMS IN A HETEROGENOUS NETWORK ENVIRONMENT

Abstract

This paper deals with a design and implementation of an intrusion detection system in heterogeneous network environment. The work includes work out characteristics of Intrusion detection systems, it`s base classification, development of problematic, building structure, used strategies of analyses in intrusion detectio and studies of placement the detectors of system. The scope of this work is to design and to implement the Intrusion detection system with uses the anomaly detection analyses, concrete statistical methods, in target of the third layer of ISO/OSI model. In implementation of the work is using the knowledge from area of the programming in C language and the modular programming, and the knowledge from area of the computer networks mainly from the building a networks traffic up to third layer of ISO/OSI model. The work includes the classification of implemented system and the experimental verification of the system functionality on the real specimen of network traffic from different network environments.
