Abstract

Today's Intrusion detection systems when deployed on a busy network overload the network with huge number of alerts. This behavior of producing too much raw information makes network based intrusion detection systems less effective. We propose a system which groups and analyzes the alerts generated by Snort to visualize possible intrusions in a network. Our Visualization model contains two components. Our first component gives the network administrator with the logical topology of the network and detailed information of each node that involves its associated alerts and connections. The second visualization component, flocking model, presents the network administrator with the visual representation of IDS data in which each alert is represented in different color and the alerts with maximum similarity move together. This gives network administrator with the idea of detecting various of intrusions through visualizing the alert patterns.
