NetSecRadar: A real-time visualization system for network security: VAST 2012 Mini Challenge. Award: Honorable mention for interesting use of radial visualization technique

NetSecRadar is a visual analytics system to aid in monitoring the network security in real time and perceiving the overall view of the security situation using radial graph. At present, we use this tool mainly for IDS alerts to analyze the irregular behavioral patterns, and synthesize interactions, filtering and drill-down to detect the potential intrusions. In conclusion, we describe how this system was used to analyze the mini-challenges of the 2012 VAST challenge.
