Different Techniques to Detect Botnet

Abstract

Botnets are now considered as one of the most serious security threats. In contrast to previous malware, botnets have the characteristics of command and control (C&C) channel. Botnets usually use existing common protocols, eg IRC, HTTP and in protocol conforming manners, this makes the detection of botnet C&C a difficult problem. In this paper we tend to proposed 3 techniques specifically signature based detection, firewall IP blocking and anomaly based detection so as to detect bot and provide secure network services to the users.
