A Detailed Study in Existing and Prior Studies about Security of Software Defined Networks

Abstract

SDNs (Software Defined Networks) are modern models and drawn the attention of several
scholars since their debut. This paradigm was primarily centred on separating networks
because control and data levels in old networks were configured within same equipments,.
Architectures of SDNs have a bright future in the world of networks since they offer
advantages of separating controls from data transmissions and have the ability to design and
add features as and when needed in a flexible way. Despite numerous benefits given by
SDNs, the issue of security cannot be disregarded. Many studies have proposed schemes to
counter security vulnerabilities in SDNs and create safer architectures. This survey on
security of SDNs is split into three parts namely their general structures, and issues and
attacks that can affect their structures. Important design attempts are also detailed considering
future needs of secure SDNs.
