Novel privacy vulnerabilities and challenges of OpenFlow-based SDN in network security

In the last decade, software defined networking (SDN) with novel mobile network environment hasdrawn so many attentions from both IT industries and academic because of its huge convenient andeconomic cost. Advanced mobile networks provide abundant entertainments and rich lifestyle forcitizens, which requires larger storage and higher quality of internet environments such as innovativemobile cloud computing and especially potential SDN [1]. Then emerging SDN technology satisfyingmore users’ demands gains a lot of momentum, which is a new network structure with highersecurity than traditional networks. Meanwhile, novel vulnerabilities and challenges play the mostimportant roles in the deployment of software defined networking. In this paper, at first, we brieflyintroduce software defined networking including three main planes. Then OpenFlow-based SDN areillustrated. The procedure of OpenFlow-based SDN working is also provided in this part. And relatedsecurity vulnerabilities and challenges on each layer are presented in the last part.
