Model Survey on Policy Making for Software Defined Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 11
Abstract
As the nature of threat is evolving day by day so it very important that network defence method should also evolve. This lead in increased demand of Software Defined Network(SDN) and OpenFlow, the policy based network management and security. It is very difficult task to manually configure multiple devices in a network so it is being replaced by automated approach where a software based, network controller handles the configuration of devices. We propose OpenSec, an OpenFlow based security framework that allows a network security operator to create and implement security policies in human-readable language. SDN consist of decoupling the control and data planes in a network. It relies on the fact that the simplest function of a switch is to forward packets according to a set of rules. OpenSec converts security policies into a series of OpenFlow messages needed to implement such policy. Different techniques like Intrusion detection, spam detection, data packet inspection are having performance issues regarding space and time. So, this paper concentrates on analysing different techniques and to find a proper way to improve Policy based Security over a network.
