| Abstract: | In order to reduce the false positive rate of anomalous intrusion detection systems and to enhance their the self-adaptability of the system,based on the concepts of completeness and self-similarity of knowledge base,a novel anomaly detection model with self-adaptability is proposed.The intrusion detection system based on this model can adjust its threshold automatically to identify anomalous or normal behaviors according to its evolving knowledge.Hence,the self-adaptability of the intrusion detection syste... |
