Botnet detection based on common network behaviors by utilizing Artificial Immune System(AIS)

Botnet is most widespread and occurs commonly in today´s cyber attacks, resulting in serious threats to our network assets and organization´s properties. Botnets are collections of compromised computers (Bots) which are remotely controlled by its originator (BotMaster) under a common Commond-and-Control (C&C) infrastructure. In this paper, we proposed a new general Botnet detection framework. Since Artificial Immune System (AIS) is a new bio-inspired model which is applied for solving various problems in the field of information security, we used this concept in our proposed framework to make it more efficient. Our framework is based on definition of Botnets. Botnet has been defined as a group of bots that perform similar communication and malicious activity patterns within the same Botnet. We utilized AIS to effectively detect malicious activities such as spam and port scanning in bot infected hosts.
