Novel Misuse Intrusion Detection Model with Self-Adaptability
Liu Zhe-shu · Journal of Shanghai University of Engineering Science · 2007
In order to reduce the false negative rate and improve bad self-adaptability of intrusion detection systems the concepts of completeness degree and self-similarity of the rule set were defined.A novel misuse intrusion detection model with self-adaptability was proposed.The model makes use of fuzzy pattern recognition technique.The intrusion detection system based on the model can adjust its threshold to identify abnormal or normal behaviors according to its evolving knowledge.Hence the false negative rate of intrusion detection systems is reduced. Its accuracy and self-adaptability is improved.
