XU Dong-ping · Computer Knowledge and Technology · 2008
instrusion detection technique is an important safety precaution in internet,but the current instrusion detection system cannot meet the actual demands because of the high false alarm and false negative rates .Analyzes the limitations of intrusion detection system which is based on pattern matching, puts forward a model which protocol analysis and pattern matching are combined,Such combination can steadily reduce computational load, enhance the analysis efficiency and obtain the more accurate result.
