Abstract

With the ever growing deployment of networks and the Internet, the importance of network security has increased. Recently, however, systems that detect in- trusions, which are important in security countermea- sures, have been unable to provide proper analysis or an effective defense mechanism. Instead, they have overwhelmed human operators with a large volume of intrusion detection alerts. This paper presents a new approach for handling intrusion detection alarms more efficiently. We propose here an architecture for automated alarm filtering based on classical method of clustering (Self-Organizing Maps) coupled with proba- bilistic graphical model (Bayesian belief networks) for determining if the network is really attacked.
