As an active network security technology, intrusion detection can not only find outer intruders’attack, but also detect inner legal users’unauthorized operation. Hence, it is regarded as the second network security gate behind firewall. At present, many researchers have applied support vector machine(SVM) as a machine learning method to intrusion detection and obtained certain studying achievements.
