Abstract
The rapid development of internet technology makes the hacker’s attack more mature and diversified. One of the most serious security problems is distributed denial of service (DDoS) attack. In order to cope with information security issues, a new form of defensive thinking, moving target defense (MTD), has been proposed. The emergence of new network architecture software defined network (SDN) and network function virtualization (NFV) - has also changed the future of network security schemes. In this paper, an SDN/NFV-based moving target DDoS defense mechanism using multiple fuzzy systems and a proxy virtual network function (VNF) is proposed to achieve DDoS detection and mitigation. The experimental results show that the proposed mechanism can redirect suspicious traffic and quarantine it, thereby shifting the attack surface.
