Security of Software Defined Network

Abstract

Software Defined Networking (SDN) might be a particular methodology that allows the system to be brilliantly and midway controlled, or 'modified,' utilizing programming applications. Software Defined networks technology can help to run on-demand applications for satisfying today’s business needs that is the reason for its extensive use in mostly data center .Software defined network, i.e. SDN provides clear view of whole network architecture to the network administrator. It isolates the system's control and sending capacities to such an extent that the physical and legitimate systems can be dealt with autonomously. This helps operators manage the whole network consistently and holistically, no matter the underlying network technology. This method allows the network traffic to flow according to the changing needs of the business without changing in the network’s architecture. As we see in the modern time the network becomes more complex and managing all these networks by using traditional networking approaches is quite difficult. Software defined network is a better approach for handling large network and using all the network component efficiently. To accomplish a far reaching organization SDNs these systems found a good pace against inner and outer abuse. Compromised controllers, end hosts and switches can be easily exploited to launch a number of attacks against the network. In this work we emphasize on number of security attacks on the network and how we secure our networks from these attacks.
