2SECURITY CHALLENGES IN NETWORKINGPart 1: Security Aspects in Software Defined Networkingi) Introduction to SDNSoftware defined networking or SDN is a typical approach towards the technology of cloudcomputing, which eventually facilitates the management of networking and also allows excellentconfiguration of network programmatically [5]. This network configuration is enabled for theimprovement of network monitoring and performance. Moreover, SDN helps in addressing thetypical fact that static architecture of any traditional network is more complex and decentralized,whereas, the architecture of the current network needs maximum flexibility and troubleshooting.Software defined networking centralizes the network intelligence in any one specific component ofnetwork by simply detaching the procedure of forwarding of any data packet from the process ofrouting [12]. This process of routing comprises of at least one controller, also known as the brain ofany software defined network. The incorporation of network intelligence is done here. However,there are few disadvantages as well in the security of this network. There are three distinct layers in software defined networking. They are as follows:i) Data Forwarding Layer: This the primary layer of a SDN. The network devices of this layermainly include router, local area network switch, packet switch and other network devices. Thislayer is also known as data plane. It helps in forwarding the traffic to the next hop with a specificpath to the chosen network destination [11]. The packets of the data plane layer go via the routerpresent in the layer. The switches or the routers of the data forwarding layer utilize what the layer ofcontrol plane is made for the disposal of the incoming or the outgoing packets and frames. ii) Control Layer: This is the second layer of software defined networking. The SDN controlsoftware in this layer includes routing, traffic engineering and mobility. The control layer isresponsible for the decision making regarding the destination of traffic [1]. Moreover, the routeralways initiates the packets of the control layer. The major functions of this layer are systemmanagement, configuration and also the exchange of the information of routing table. This layer isalso known as the signalling of a network. iii) Application Layer: This is the third layer of software defined networking. The applicationsof this particular layer mainly include the business applications, SDN applications and cloudorchestration [2]. These applications are typical programs, which can explicitly or directlycommunicate with the controller of SDN for the requirements of network.
