Abstract

See full text

A system and method are provided for detecting a botnet in a network based on traffic flow, daisy chained mechanism and white-list generation mechanism. The system and method uses the known malicious components in a botnet such as IP address, domain name and URL, to be the root of a daisy chain and creates a network graph based on given traffic flow data such as NetFlow data, DNS cache data, DNS sinkhole data, DDoS data and Attack log data in threat sensors. The system and method iteratively detects new malicious factors by tracing that network graph. The system and method also introduces a technique to create a white list which is used in the daisy chain to reduce false positive.
