Traceback Framework against Botmaster by Sharing Network Communication Pattern Information

In order to exterminate a botnet, we have to trace a botnet and arrest its botmaster. In this paper, we make a model of communication pattern of a C&C server that sends/receives packets to/from the botmaster. Then we discuss how botmaster trace back can be achieved. We describe which communication patterns we should focus on to find the botmaster or upper C&C servers. Furthermore, we propose a framework for botmaster trace back. In this framework, owners of servers which become to C&C server will collaborate and share the communication patterns for trace back. To do this, we propose the information sharing using communication pattern monitoring tools with the servers.
