Abstract
IDS (Intrusion Detection System) is an active research topic for the purpose of cost reduction of security maintenance of computer network. However, existing IDS technologies still have some issues, including enormous log output data, and lack of analysis technologies of complicated behavior of recent intrusions. This report proposes a technique to support understanding and exploration of such behavior of intrusions, by applying an information visualization technique. The technique constructs hierarchical data according to IP addresses of computers in a target network, and visualizes the data by Heiankyo-view, which is a new technique for hierarchical data visualization. By mapping statistics of intrusions onto the visualization display, we could observe some behavior of real intrusions.
