Distributed Intrusion Detection Systems: An Overview

Abstract

The recent tremendous increase in the malicious usage of the network has made it necessary that an IDS should encapsulate the entire network rather than at a system. This was the inspiration for the birth of a distributed intrusion detection system (DIDS). Different configurations of DIDSs have been actively used and are also rapidly evolving due to the changes in the types of threats. This chapter will give the readers an overview of DIDS and the system architecture. It also highlights on the various agents that are involved in DIDS and the benefits of the system. Finally, directions for future research work are discussed.
