The current problems raising as a horizon in the computational and networking sector is based on the unimaginable increase of high numbers of users which in turn results in high data traffic, limitations over products which are vendor specific, incurring high expenses in maintaining the existing network. This dilutes a major part of the beneficiaries in the sector to move towards Cloud Networks. All these happenings in the past has quietly increased the risks and challenges in the aspect of security considering both data and the infrastructure accommodating the data. In an attempt to address almost a major portion of the existing above said problems, Software Defined Networking was highly anticipated, however, it was considered as a theoretical approach. After the implementation of SDN networks by industrial giants like Google, the SDN concepts again managed to reach the safer hands of the researchers in the movement of enhancement. A very rapid and high speed research work has been initiated by researchers all around the globe in analysing the risk factors and implementation barricades stated in the Software Defined Networking architecture. The research work focus on adding values to the Quality of Service, Latency, Load Balancing and most importantly the security aspects in various metrics of the Software Defined Networking Architecture. The odd man out architecture of Software Defined Networking by decoupling data and control plane allows the network to be configured and maintained in a real time scenario pertaining to pose a complete view of the network and its flow. The fact that is considered as an advantage itself is a factor of question in the case of security in the overall SDN architecture. This paper focuses on a detailed view of SDN architecture with the existing security feature and continues with the expected threats and classifying the weak points in the SDN. This paper also briefs about the pros and cons of the existing applications in the SDN architecture.

Software-defined networking (SDN) is an emerging network architecture that facilitates the network administrator to control and manage network behavior dynamically. Different from traditional networks, software-defined networks support dynamic and scalable computing. The dynamic behavior is achieved by decoupling or disassociating the system. The swing of control from tightly bound individual networks to assessable computing devices enables infrastructure abstraction. Due to the abstraction, the network can be considered as a logical or virtual entity. In this chapter, relation between network function virtualization (NFV) and software-defined networking (SDN) has been outlined. This chapter focuses on describing the pros and cons of NFV technologies. network functions virtualization (NFV) was founded under the work of the European Telecommunications Standards Institute (ETSI).
