IDS Alert Classification Model Construction Using Decision Support Techniques

摘要

Although many IDSs have been proposed to assist administrators in detecting intrusion, false alarms are still huge and result in the difficulty of analysis. For this reason, we proposed a decision support system for constructing an alert classification model, which consists of three phases: alert preprocessing, model constructing and rule refining. Experimental results show that the proposed method discovers intrusion patterns quickly and precisely, and lightens the load of on-line alert analysis for experts obviously.
