Abstract:

It is a hot research point to adopt data mining to expand intrusion detection systems＇ capability in order to detect new attacks. In this research,we apply the k_NN classifier to IDSs based on various data mining algorithms. We present k_NN for IDSs, an algorithm which is used for intrusion detection based on the k_NN classifier. Finally, we give a detailed description on using the k-NN classifier for IDSs, and prove the effectiveness of this mended  algorithm on KDD99.

Key words: （k-NN classifier, IDS, normalized, information gain, weighted, k-NN for IDS）
