A New Intellectualized Intrusion Detection System

A new intrusion detection system(IDS) with repect to three maching-learning technologies including fuzzy comprehensive evaluation(FCE),genetic algorithm(GA) and BP neural network(BP) is proposed.In this paper,we outline reasons for the introduction of the above three technologies with the evaluation criteria of IDS,and further discuss how to integrate the above technologies in the IDS,including establishment of a base model by FCE,optimization of parameters in the membership functions by GA,and study and judgment of the IDS by BP,which has enhanced the IDS rapidity,accuracy and adaptability.
