Network infrastructures are growing rapidly to meet the needs of business, but the required repolicing and reconfiguration provide challenges that need to be addressed. The software-defined network (SDN) is the future generation of Internet technology that can help meet these challenges of network management.

This book includes quantitative research, case studies, conceptual papers, model papers, review papers, and theoretical backing on SDN. This book investigates areas where SDN can help other emerging technologies deliver more efficient services, such as IoT, industrial IoT, NFV, big data, blockchain, cloud computing, and edge computing. The book demonstrates the many benefits of SDNs, such as reduced costs, ease of deployment and management, better scalability, availability, flexibility and fine-grained control of traffic, and security.

ABSTRACT

The exponential rise of data/information and network resources made most of the organizations investing their resources to develop the biggest data centers (DCs) to accommodate. In the process, controlling the workload at the DCs with minimum response time, there is a need for an effective load-balancing system for which routing applications are playing an important role. Some of the routing applications based on software-defined networking (SDN) available in the market handling the traffic loads of these DCs efficiently. Using the centralized routing allows the network engineers to adjust different types of network elements such as switches, links, and ports dynamically based on the traffic loads. The data flow management at these DCs is managed by the routing applications sometimes face a non-conflicting way for the flow of data and towards the instructions for the switches as well. The security of routing applications plays an important role in safeguarding the control of data flow routing or scheduling from the attackers. The possibility of attackers controlling the traffic, servers, and switches at a DC is a serious threat and someone may even shut down the complete system/server. Such attacks may disrupt the routing application and also data flow management. In this chapter, various challenges and security analysis of SDN concerning to routing, cloud, Wi-Fi, and big data will be explored. Different types of design considerations for security requirements are discussed with considerable examples and code analysis. SDN cloud applications and security challenges that are related to the cloud are explained with detailed analysis. Some of the mitigation techniques are proposed for spoofing, data tampering, and repudiation issues. In addition, a detailed discussion on the big data using Apache Hadoop for processing and analyzing the large data sets will be explored.

1.1 INTRODUCTION TO SECURITY ISSUES OF SDN

SDN is one of the best examples of networking standards aiming towards reaching the goals of overcoming the limitations existing with the traditional networks. SDN enables the software to manage the networks dynamically (Sahoo et al., 2019a). Using the software, abstracting of a physical network with the virtual networks is possible using SDN. Apart from that it helps spanning the policies across the physical and virtual networks and allows controlling the data centers (DCs) traffic flow. The performance of SDN lies in the ability of providing consistent policy enforcement, ability to deliver greater scalability and the ability to control entire network from the centralized management systems. Most of the security solutions with SDN are useful for the improvement of policy enforcement, traffic anomaly detection and for the mitigation of serious threats (Hizver, 2015). The possibility of getting under the malicious attacks by a new system using SDN functions is more and some of the attacks are quite common in other existing networks. Some characteristics of SDN are listed below before understanding the security issues:

• They are centrally controlled networks;
• They consists of open programmable interfaces;
• They use switch management protocols;
• Flexible for third party network services;
• They are also known to be the virtualized local networks;
• They consist of centralized monitoring units.

Physically the SDN Controllers (SDN-Cs) are distributed and will be in a cluster form. They will maintain a proper hierarchy and each controller will be having defined number of tasks to control the forwarding domains. However, network security using the SDN helps to improve the control and containment of variety of network security threats. However, found to be very sensitive for Denial-of-Service (DoS) attacks, issues that are related with trust among the networks, and it is proved to be bad due to the lack of better SDN functions and components to deal with network security issues.

1.1.1 SOFTWARE-DEFINED MOBILE NETWORKS (SDMN)

In recent times, most of the mobile operators are facing serious challenges with the rapid growth of mobile (smart) phones and wide range of network services. Most of the network services such as video streaming, television programs on internet, voice over internet protocol (VoIP), electronic transactions, video streaming, cloud servi...
