Zombie PC Detection and Treatment Model on Software-Defined Network

The DDoS attack is one of the biggest threats in traditional network infrastructures which increases every year. This threat of making the target unserviceable still exists in the newly arising network architecture called SDN. In this paper, we propose a model for detecting zombie PCs, which are systems infected by malware used for launching the DDoS attack, on the SDN. Using this model, we can block malicious packets from the local network which generates them. It can also detect and treat zombie PCs, vulnerable hosts, to improve the security of both end host and local network.
