Using SDN to Enhance IoT Security

Abstract

Use of Software Defined Networking in critical networks such as smart cities, depends on safe and functional control applications. This thesis proposes a blueprint for an effective development and implementation of such applications. The blueprint describes a 6-step development process, which gives a general guide of how to progress with the application development with security in mind. The blueprint then focuses mostly on the second phase - analysis - as it summarizes and presents a list of application requirements. Finally, the blueprint analyses the most common security threats and proposes approaches to mitigate these threats by Software Defined Networks. In the last part of the thesis, the blueprint is verified on a use case application of a smart city protection system, specifically developed for this purpose.
