Comparative security analysis of software defined wireless networking (SDWN)-BGP and NETCONF protocols

Software Defined Networking (SDN) is getting much attention for larger network implementation adding programmable feature in the network plane. Demand of wireless networking features is growing simultaneously. With increased network complexity and sizes, security has become an issue as vulnerabilities are still prominent for such complex network and needs to be monitored properly to provide early detection of security breaches and Denial of Service attack. Therefore, the communication protocols, an SDN architecture uses including OpenFlow, NETCONF, OpFlex and BGP etc. should be secure enough to manage such complex and large network. This paper analyzes mostly used protocols specifically for Software Defined Wireless Networking (SDWN): BGP, NETCONF, for underlying cloud or data center environment by applying Microsofts STRIDE security threat model. This work represents a comparative study among these most used protocols and holds appropriate network for their deployment.
