An Algorithm of Intrusion Detection Based on Fuzzy Comprehensive Evaluation
Huibin Lu · Jisuanji fangzhen · 2009
The security measures of computer communication network-intrusion detection system is presently a hotspot,and intrusion detection technology,especially fuzzy intrusion detection technology has got an unprecedented development.But there is generally a problem of high rate of false alarm.Through studying intrusion detection algorithms,aiming at the problem cased by fuzzy technique,the paper proposes a detection algorithm by combining protocol analysis with fuzzy comprehensive evaluation,and the algorithm carries out protocol analysis before fuzzy comprehensive evaluation,that's to say,according to different types of protocol,different weight vectors and different fuzzy comprehensive evaluations based on evaluation matrix composed of vectors judged by a single factor are adopted.The results show that this method results in better detection,has very high detection rate and very low false alarm rate.
