The network intrusion event data in KDD CUP99 dataset is used to perform the instance study for the network security intrusion events analysis model. The test results show that the analysis model has more recognition accuracy than the model established by the conventional neural network algorithm,and can accurately identify and analyze the normal events and four network attack events.
