An approach for detection of attacks in software defined networks

摘要

Software Defined Network is new turning up prototype architecture which efficiently separates the controlling and forwarding planes to provide flexibleness for the network manager to acquire control over network centrally. This centralized concept of SDN provides lower costing with maximum visibility of network and high throughput. Using smart devices in the network, SDN contributes to make use of network virtualization, which in turn helps in energy conservation and centralized security for increasing overall performance of the network. Software defined networking represents a latest approach at how networks are operated through centralized system. The SDN controller is the heart of SDN architecture where we can apply customized security rules and policies for every data flow in the network. Controller provides decision making facilities when malicious traffic is generated. Our approach in this project is to design security policies for the controller for detecting DDOS attacks and take action against it.
