Cloud based firewall on OpenFlow SDN network

Abstract

Security is a major problem in networking. Corporates and Service providers spend much money on highly priced firewalls to implement security. Software-Defined Networking (SDN) is a new structure that can save Corporates and service providers money, reduce provisioning time from days to minutes, provides centralized management, allow programmability in the implicit Network. SDN accomplishes this by decoupling the control plane from the data plane. This paper demonstrates the benefits of implementing a Cloud based firewall on OpenFlow SDN network, which is a way of implementing SDN. The firewall has the capability of identifying application layer traffic, like social Medias and other websites and excluding some Denial-of-Service Attacks. This paper handles the implementation information and give a performance analysis of the firewall component.
