Project Summary:

Software Defined Networking (SDN) and Network Functions Virtualization (NFV) are emerging technologies in the fields of telecommunications and networking. In combination, SDNFV introduces a programmable, dynamic, and flexible network topology. All network topologies are vulnerable to cyber-attack and the traditional protection against attack has been a perimeter defence approach tuned to the target topology. However, the perimeter defence is no longer valid with the dynamic nature of SDNFV and an increasing volume of virtual network appliances that can be introduced or removed from the network on-demand. In order to secure dynamic software-defined networks with virtualized functions, new protection mechanisms are required.

The main goal of this PhD thesis is to investigate and derive custom purpose traffic monitoring and forensics tools and remediation techniques for SDNs that exploit intelligence harvested from the network for resource management, network security, integrity and control.

Academic Requirements:

Students entering the programme will normally be required to have a 2.1 BSc/BEng in Computer Science, Electrical and Electronic Engineering, or a maths based engineering or physical science degree, or equivalent qualification recognised by the University.  Students holding an appropriate MEng or MSc (Software conversion) will normally be required to have a 2.1 or commendation (distinction) respectively.  Furthermore, additional criteria may be applied. All applicants must have significant mathematical and programming experience.
