Application of support vector machine in intrusion detection

Intrusion detection is one of the important fields in network security.The serious security problems require better performance for intrusion detection system.Support vector machine(SVM) is an effective learning tool for small size samples.After its successive application in letter recognition,face recognition and so on,it found its application in intrusion detection.The applications of many al-gorithms of SVM,such as two_class SVM,one to two class SVM,multi_class SVM and the algorithm solving training on large training samples in intrusion detection are introduced.Detecting intrusion using SVM improves the detection performance.
