Analysis of high resolution DNS data reveals intricate patterns. This presentation offers visualizations of 24 hours of query data for provider resolvers across time, type, TLDs, and names for both legitimate and malicious traffic. Drill downs into threat details – such as bot, DDoS, and malware will be presented. Other query data will also be evaluated and displayed.
