Policy-based Information Sharing using Software-Defined Networking in Cloud Systems

TL;DR: This research explored how to enforce the policies related to the resources inside a Virtual Machine (VM), apart from providing initial access control, and considerd various components in the cloud to deduce a multicost function, which in turn helps to regulate the cloud.

Abstract: Cloud Computing is rapidly becoming a ubiquitous technology. It enables an escalation in computing capacity, storage and performance without the need to invest in new infrastructure and the maintenance expenses that follow. Security is among the major concerns of organizations that are still reluctant to adopt this technology: The cloud is dynamic, and with so many different parameters involved, it is a difficult task to regulate it. With an approach that blends Usage Management and Statistical Learning, this research yielded a novel approach to mitigate some of the issues arising due to questionable security, and to regulate performance (utilization of resources).This research also explored how to enforce the policies related to the resources inside a Virtual Machine(VM), apart from providing initial access control. As well, this research compared various encryption schemes and observed their behavior in the cloud. We considerd various components in the cloud to deduce a multicost function, which in turn helps to regulate the cloud. While guarenteeing security policies in the cloud, it is esential to add security to the network becuase the virtual cloud and SDN tie together. Enforcing network-wide policies has always been a challenging task in the domain of communication networks. Software-defined networking (SDN) enables the use of a central controller to define policies, and to use each network switch to enforce policies. While this presents an
