Abstract
A method and system for detecting domain name system (DNS) recursive cyber-attacks are presented. The system includes learning a plurality of baselines of at least rates and rate invariants of DNS features; monitoring DNS traffic directed to and from a DNS resolver, wherein the DNS resolver is communicatively connected between at least one client and at least one name server; analyzing the monitored DNS traffic using at least one detection function to detect an anomaly based in part on at least one baseline of the plurality of learnt baselines; and upon detection of at least one anomaly, performing at least one mitigation action to filter out incoming DNS queries to a domain name under attack.
