A Network Intrusion Detection System (NIDS) is an alarm system for networks. NIDS monitors all network actions and generates alarms when it detects suspicious or malicious attempts. A false positive alarm is generated when the NIDS misclassifies a normal action in the network as an attack. We present a data mining technique to assist network administrators(More)
With the ever-growing web traffic, cluster-based web servers have become very important to the Internet infrastructure. Thus, making the best use of all available resources in the cluster to achieve high performance is a significant research issue. In this paper, we present Weblins, a cluster-based web server that can achieve good throughput. Weblins has(More)
With the ever growing deployment of networks and the Internet, the importance of network security has increased. Recently, however, systems that detect intrusions, which are important in security countermeasures, have been unable to provide proper analysis or an effective defense mechanism. Instead, they have overwhelmed human operators with a large volume(More)
A network intrusion detection system (NIDS) monitors all network actions and generates alarms when it detects suspicious attempts. We present a data mining technique to assist network administrators to analyze and reduce false positive alarms that are produced by a NIDS. Our data mining technique is based on a growing hierarchical self-organizing map(More)
La détection des tentatives d’attaques sur un réseau est une problématique très importante dans le domaine de la sécurité informatique. Les NIDS (Network Intrusion Detection Systems), systèmes de détection d’intrusions, génèrent tellement d’alertes sur un réseau qu’il en devient très difficile de déterminer celles générées par une attaque réelle.(More)
