Software-defined networking (SDN) is a network architecture approach that allows programmatic management of network resources using software applications. This technology helps operators manage the network configuration and traffic engineering from the underlying network technology.

Technology is getting more advanced from time to time, the traditional network architecture model does not support the demands of modern business IT. Organizations seeking new solutions to support dynamic computing environments. Software Defined Networking offers characteristics such as Decoupled Architecture Planes, Network Operability, and Openness & Interoperability to address concerns that organizations have.

This project is to investigate whether the technology SDN meets security considerations. Security is the key point for organizations.

We will discuss the concepts about virtual network security first, then we will consider proactive security using moving target defense. Next, we will review attack representation models based on attack graphs and attack trees. Finally, we will examine if service function chaining in virtual networks will meet security considerations.
