Adaptive Intrusion Detection System

The basic concepts of intrusion detection technique are discussed. The key technique and some issues on the current intrusion detection system are analyzed. In order to solve problems existing in a traditional intrusion detection systems, framework model for an adaptive intrusion detection system (AIDS) is proposed. The basic theory of the system model is introduced, and its structure and main functions analyzed. The adaptive model generation approach streamlines and automates the process of collecting data, building models, and distributing the models to detectors. The proposed model is an open system having good scalability and adaptability, and can reduce signigicantly the cost of deploying an IDS system. The problems of environment adaptability are solved, the cost of building a model is reduced, and the efficiency of the system is improved.
