INTRODUCTION Background of studySoftware defined networking is referred as an approach for computer networking whichprovides permission to network administrators to manage and maintain network services with thehelp of abstraction of higher level functionality. It is a dynamic, manageable, cost-effective andadaptable process (Sezer and et.al., 2013). SDN plays essential role in network security. It has bothadvantages and disadvantages. There are various methods or techniques which can help thecompanies in improving and increasing their network security (Pitt, 2013).With respect to this, present study will be conducted to identify the role of software definednetworking (SDN) in increasing network security. It will use literature review from various sources,research methodology techniques, data collection tools, ethical considerations, project plan andmany other factors for achieving the appropriate results.Rationale: What is an issue: With the increase in use of various techniques, problems regarding thenetwork security are also enhancing. It becomes difficult to keep personal and confidentialinformation safe and secure from the unauthorised access. Why it is an issue: Improper network security is providing opportunity to the hackers orthird party to access important information of the organisations. Due to this, competitors canalso access confidential information of the leading companies for determining theirstrategies and processes (Porras and et.al., 2012).Why it is an issue now: Companies are taking major actions for enhancing their networksecurity but they are not able to remove this problem permanently. This issue is creatingwastage of time, resource and money. Research will shed light on: For resolving the problem of network security, this researchwill shed light on using SDN. It will explain various methods and strategies for increasingnetwork security of the organisations with the help of SDN.Aims & Objectives: Aim: To identify the role of Software defined networking in increasing network security Objectives: To understand the concept of software defined networkingTo identify the issues faced by organisations in network securityTo determine the relationship between software defined networking and network securityTo suggest the appropriate software defined networking methods for enhancing network2

securityResearch Question What is the concept of software defined networking? What are the issues faced by the organisations in network security? What is the relationship between software defined networking and network security? What are the appropriate software defined networking methods for enhancing the networksecurity?Significance of the research: The present research possesses significance for both academic and corporate perspective.Results of this investigation will support students of various levels to get detail knowledgeabout SDN and its contribution in enhancing network security. This will also make awarethem about various network security problems faced by the companies in real world. Thisinvestigation will help PhD scholars in enhancing their knowledge in this particular fieldand career opportunities. Along with this, various organisations will be able to use this studyfor understanding the relationship between the SDN and network security. They can alsotake help from this research for selecting appropriate SDN method for resolving their issueregarding network security (Nadeau and Gray, 2013).

According to the Govindarajan and et.al., 2013 “SDN plays essential role in directing theproper way for managing and maintaining network resources in an on-demand way. But stillsome organisations are facing challenges in accomplishing Quality of Service (QOS),optimal load balancing, scalability and security (Govindarajan and et.al., 2013). In favour tothis Feamster, Rexford and Zegura, 2014, has stated that “SDN is a network architecture inwhich forwarding state of the data plan is managed by the remote control plane decoupledfrom the former. The main foundation element of the SDN is open flow protocol. Thearchitecture is directly programmable, agile, centrally managed, programmaticallyconfigured and open standards based and vendor neutral” (Feamster, Rexford and Zegura,2014). With respect to this, researcher will focus on various aspects of the SDN forachieving the objectives of the study. Network Security:As per the view of John and et.al., 2013, “Network security refers to the protection of filesand directories in a computer against unauthorised access and misuse. It includes variouspolicies and procedures which are implemented by the network administrator for preventingand monitoring the modification or denial of a computer network and its accessibleresources” (John and et.al., 2013). Similarly Qazi and et.al., 2013, has said that “Networksecurity is a strategy and provision of the companies for checking the security of their assetsand network traffic. They need to implement proper security policies, procedures, hardwareand software for ensuring the safety and security of their files and folders” (Qazi and et.al.,2013). Network Security Issues: According to Batuula, 2014, “Cybercriminals uses various methods and approaches foraccessing important and confidential information of the companies. All organisations are required tobe aware of all kind of network security problems so that they can take effective and appropriateactions” (Batulla, 2014).Spoofing:Nunes and et.al., 2014, has stated that “Spoofing is a kind of network security threat inwhich an intruder tries to get unauthorised access to the computer system of company by acting tobe the user. In this, a message is delivered by the trespasser with the help of an IP address whichshows that message is coming from a trusted user or a host” (Nunes and et.al., 2014).Hijacking:Pan and Nadeau, 2012, has said that “Hacker takes the benefits of the loopholespresent in TCP/IP protocol. It generally occurs when third person between the two peopleactively monitors, capturers and controls the communication. Man in middle attacks is one of4
