Single Flow

Software-defined networking (SDN) allows centralizing and simplifying network management control. It brings a significant flexibility and visibility to networking, but at the same time creates new security challenges. The promise of SDN is the ability to allow networks to keep pace with the speed of change. It allows frequent modifications to the network configuration. However, these changes may introduce misconfigurations by writing inconsistent rules for single flow table or within a multiple open flow switches that need multiple FlowTables to be maintained at the same time. Misconfigurations can arise also between firewalls and FlowTables in OpenFlow-based networks. Problems arising from these misconfigurations are common and have dramatic consequences for networks operations. To avoid such scenarios, mechanisms to prevent these anomalies and inconsistencies are of paramount importance. To address these challenges, the authors present a new method that allows the automatic identification of inter and inter Flowtables anomalies. They also use the Firewall to bring out real misconfigurations.

Software Defined Networking (SDN) is a modern emerging technology in networking. SDN desires to furnish with composite and exclusive networking sources, it needs to decouple of carrier plane and the control plane, and also provides centralized control. The benefits of network programmability, dynamic computing, cost effective, high bandwidth, of SDN applications are discussed, but security has become an important concern. While centralized controller controlling multiple devices, this change in traditional network will be the main impact on network security. In this paper, we discuss about security issues and challenges in SDN architecture planes.

Daunting Task

The IoT contains millions of heterogeneous smart objects that are connected together through the Internet platform. These heterogeneous smart objects deal with different protocols, technologies and resources, therefore each of them requires diverse security services in heterogeneous environments. Therefore, providing security services in heterogeneous environments is a daunting task for network providers that cannot be guaranteed through the traditional network architecture. Wide distribution and openness of IoT smart objects makes them very vulnerable to attacks and it can be easily targeted by cyber-attacks. Software-Defined Networking (SDN) is a new paradigm that separates the control plane from data plane t a global network view by centralized controller. Integrating the software-defined network with the Internet of Things can provide better access control and security mechanisms. Software-defined networking provides better control and management possibilities to manage and secure Internet of Things in a good manner. In this paper, we discuss about IoT architecture, security challenges in IoT, SDN architecture, security challenges in each layers of the SDN and software-defined IoT. In addition, we provide solutions to security problems in IoT through software-defined networking approach.
