In this dissertation, a formalism for flow rule conflicts in SDN environments is introduced. This formalism is realized in Brew, a security policy analysis framework implemented on an OpenDaylight SDN controller. Brew has comprehensive conflict detection and resolution modules to ensure that no two flow rules in a distributed SDN-based cloud environment have conflicts at any layer; thereby assuring consistent conflict-free security policy implementation and preventing information leakage. Techniques for global prioritization of flow rules in a decentralized environment are presented, using which all SDN flow rule conflicts are recognized and classified. Strategies for unassisted resolution of these conflicts are also detailed. Alternately, if administrator input is desired to resolve conflicts, a novel visualization scheme is implemented to help the administrators view the conflicts in an aesthetic manner. The correctness, feasibility and scalability of the Brew proof-of-concept prototype is demonstrated. Flow rule conflict avoidance using a buddy address space management technique is studied as an alternate to conflict detection and resolution in highly dynamic cloud systems attempting to implement an SDN-based Moving Target Defense (MTD) countermeasures.
Intellectual property (IP) is the lifeblood of the U.S. economy. Despite being an important motivator for innovation, IP laws and IP protections are largely unknown by most individuals outside of the legal field. The purpose of this work is to condense some of the most fundamental concepts in U.S. intellectual property law and describe them in an understandable way for non-lawyers. This thesis covers basic information on U.S. patents, copyrights, trademarks, trade secrets, and the ways in which they impact both science and society. Additionally, this thesis discusses the need for better IP education and presents a solution to this problem in the form of a partly completed draft for an educational book. The book itself is meant to illustrate how the research of this thesis can be utilized in introductory educational materials while also demonstrating the potential for presenting IP law concepts in a fun and visual way.
