Software Defined Networks with Intrusion Detection Scheme

Abstract

With the explosion of cloud server deployment, the response to a single user request is generated from a sequence of distributed API call(s). Such a distributed environment inherently creates a high-bandwidth of machine-to-machine interaction. Today’s networks reconfiguration are performed relatively in a static way to avoid the risk of service interruption. In case of addition & deletion of network devices like routers & switches it is very difficult to network administrator to recognize the networks & manage it to earlier constraints. It is also very difficult to apply a consistent set of access, security, quality of service (QoS), and other policies. So we need a network which is scalable, high-performance, flexible, supportive & programmable. The new network called Software Define Networking (SDN) provides open interfaces that enable network administrator to develop a software that can control the connectivity provided by a set of network resources and the flow of network traffic through all these resources along with possible monitoring and modification of traffic that may be performed in the network. It is necessary to keep track or protect the traffic which is transferred from one machine to another, protection from unauthorized users and information must be available to authorized users when it is indeed. The solution called as Intrusion Detection Scheme, to monitor multiple types of networks traffic sharing the same physical infrastructure and protection to programmability offered by Software Defined Networks (SDN). This paper gives insight into threats detection such as Denial of service; Distributed Denial of service attacks using SDN based Intrusion Detection Scheme (IDS) using genetic algorithm.
