This book offers a detailed comparative study on Intelligent Agents-based Distributed Intrusion Detection System (IADIDS) with a fresh research approach. An Intelligent Agent architecture supported by the Evolutionary Computing based technique is proposed for intrusion detection to optimize Distributed Intrusion Detection System (DIDS). The proposed IADIDS architecture consists of two types of Intelligent Agents namely Light Weight Intelligent Agent (LWIA) and Heavy Weight Intelligent Agent (HWIA). Intelligent Agents are distributed across the Distributed Computer Networks. Groups of...
