Using Software Defined Networking To Solve Missed Firewall Architecture In Legacy Networks, Jared Dean Vogel

Theses and Dissertations

This study is concerned with migrating traditional networks and their inherent firewall architecture to Software Defined Networking (SDN) architecture to provide an initial attempt at preventing application downtime due to hidden firewall domain rules. In legacy organization environments the networking engineers, firewall teams, and application analysts are often silo groups, but Software Defined Networking (SDN) can blur the lines between these group silos.

This thesis first outlines the interworking of SDN, traditional firewall architecture and how it interacts with SDN, an experiment of implementation, and the resulting conclusions.

Testing with SDN shows we are approaching new environments where the edges …
