Study And Design Of Intrusion Detection System Based On Immune Principle

Intrusion detection system (IDS) is an automated system for the detection of intrusions in computer system. The main goal of IDS is to detect unauthorized use, misuse and abuse of computer systems by both system insiders and external intruders. After studying the working mechanism of human immune system completely this paper makes some improvement on existing artificial immune model. The modification include design of detector, costimulation , mutation and evolution of memory strings ,making the artificial immune model easier to realize. This paper also devises a network-based intrusion detection system (IDS) according the improved model. The IDS takes network packets as detecting data resource and has advantages such as detecting unknown intrusion , distributed disposition.
