Abstract

This paper proposes a visualization approach to address Domain Name System (DNS) security challenges, such as distributed denial of service (DDoS) and cache poisoning attacks.We present Flying Term, a new perceptually motivated visual metaphor for visualizing the dynamic nature of DNS queries. The addition of visual metaphors such as Stacking Graphs, Two Tone Pseudo Color, and Chernoff Face Glyph within the same application framework provide enhanced monitoring capability and situational awareness for visualizing DNS queries. We demonstrate our visualization's capability to help administrators identify and understand DNS querying behavior due to anomalies such as misconfiguration and security events with DNS query data acquired from a diverse set of caching servers on the Internet.
