Abstract

The technology disclosed herein enables identification of outlier DNS requests so the identified requests can be inspected to determine whether the identified requests may be associated with suspicious activity. In a particular example, a method provides determining characteristics of a Domain Name System (DNS) request and generating a score for the DNS request from the characteristics. The method further provides grouping a plurality of DNS requests into one or more groups based on a plurality of DNS request scores for the plurality of DNS requests. The plurality of DNS requests occurred in a specified timeframe and include the DNS request. The plurality of DNS request scores includes the score. In response to determining the DNS request is an outlier relative to the one or more groups, the method provides inspecting the DNS request for anomalies.
