Abstract: Intrusion detection systems are very important for network security. However, traditional intrusion detection systems can not identify new type of network intrusion for example zero-day attack. Many machine learning techniques were used in intrusion detection system and they showed better detection performance than other methods. A novel clustering algorithm called Density peaks clustering (DPC) which does not need many parameters and its iterative process is based on density. Because of its simple steps and parameters, it may have many application fields. So we are going to use it in intrusion detection to find a more accurate and efficient classifier. On the basis of some good ideas of DPC, this paper proposes a hybrid learning model based on k-nearest neighbors (kNN) in order to detect attacks more effectively and introduce the density in kNN. In density peaks nearest neighbors (DPNN), KDD-CUP 99 which is the standard dataset in intrusion detection is used to the experiment. Then, we use the dataset to train and calculate some parameters which are used in this algorithm. Finally, the DPNN classifier is used to classify attacks. Experiment results suggest that the DPNN performs better than support vector machine (SVM), k-nearest neighbors (kNN) and many other machine learning methods, and it can effectively detect intrusion attacks and has a good performance in accuracy.
