A Hybrid Framework for Building an Efficient Incremental Intrusion Detection System

In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As the framework has low computational complexity, it is suitable for real-time or on-line learning. We use incremental centroidbased “on-line k-Mean” clustering algorithm to implement anomaly detection system. Experimental evaluations on KDD Cup dataset have shown that the proposed framework has high clustering quality, relatively low computational complexity and fast convergence.
