Abstract:To reduce the high false positive rate and false negative rate of intrusion detection systems,this paper proposed an novel intrusion detection system(IDS) based on immunity.Presented the methods to reduce the false positive rate after analyzing creditability of IDS and false positive rate of anomaly IDS.The emphasis on constructing normal profile dynamically based on artificial immunity to restrain false positive rate, then did simulation experiment.The results show that the method can improve the detection efficiency and reduce the false positive rate and false negative rate, so it improves the creditability of IDS. ......
