Privacy And Legal Issues In Cloud Computing - The Smme Position In South Africa, Mathias Mujinga Dec 2013

Privacy And Legal Issues In Cloud Computing - The Smme Position In South Africa, Mathias Mujinga

Australian Information Security Management Conference

Cloud computing (CC) brings substantial benefits to organizations and their clients. Information technology (IT) users in developing countries, especially those in underdeveloped communities, are gaining easy and cost‐effective access to a variety of services, from entertainment to banking. South Africa has outlined a national e‐strategy that aims to improve those communities, by providing frameworks for access to information and communications technology (ICT). The products and services of small‐, medium and micro‐sized enterprises (SMME) are now reaching a wider audience through the use of technology. CC can go a long way to help government realize the national e‐strategy. There are numerous …


A Secure And Fair Resource Sharing Model For Community Clouds, Santhosh S. Anand May 2013

A Secure And Fair Resource Sharing Model For Community Clouds, Santhosh S. Anand

Graduate Theses and Dissertations

Cloud computing has gained a lot of importance and has been one of the most discussed segment of today's IT industry. As enterprises explore the idea of using clouds, concerns have emerged related to cloud security and standardization. This thesis explores whether the Community Cloud Deployment Model can provide solutions to some of the concerns associated with cloud computing. A secure framework based on trust negotiations for resource sharing within the community is developed as a means to provide standardization and security while building trust during resource sharing within the community. Additionally, a model for fair sharing of resources is …

Hasbe: A Hierarchical Attribute-Based Solution For Flexible And Scalable Access Control In Cloud Computing, Zhiguo Wan, Jun'e Liu, Robert H. Deng Apr 2012

Hasbe: A Hierarchical Attribute-Based Solution For Flexible And Scalable Access Control In Cloud Computing, Zhiguo Wan, Jun'e Liu, Robert H. Deng

Research Collection School Of Computing and Information Systems

Cloud computing has emerged as one of the most influential paradigms in IT industry in recent years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing attribute-based encryption (ABE) have been proposed for access control of outsourced data in cloud computing; however, most of them suffer from inflexibility in implementing complex access control policies. In order to realize scalable, flexible, and fine-grained access control of outsourced data in cloud computing, in this paper we propose hierarchical attribute-set-based encryption (HASBE) by …

Applying The Acpo Principles In Public Cloud Forensic Investigations, Harjinder S. Lallie, Lee Pimlott Jan 2012

Applying The Acpo Principles In Public Cloud Forensic Investigations, Harjinder S. Lallie, Lee Pimlott

Journal of Digital Forensics, Security and Law

The numerous advantages offered by cloud computing has fuelled its growth and has made it one of the most significant of current computing trends. The same advantages have created complex issues for those conducting digital forensic investigations. Digital forensic investigators rely on the ACPO (Association of Chief Police Officers) or similar guidelines when conducting an investigation, however the guidelines make no reference to some of the issues presented by cloud investigations. This study investigates the impact of cloud computing on ACPO’s core principles and asks whether these principles can still be applied in a cloud investigation and the challenges presented …


Privacy In "The Cloud": Applying Nissenbaum's Theory Of Contextual Integrity, Frances Grodzinsky, Herman T. Tavani Oct 2011

Privacy In "The Cloud": Applying Nissenbaum's Theory Of Contextual Integrity, Frances Grodzinsky, Herman T. Tavani

School of Computer Science & Engineering Faculty Publications

The present essay is organized into five main sections. We begin with a few preliminary remarks about "cloud computing," which are developed more fully in a later section. This is followed by a brief overview of the evolution of Helen Nissenbaum's framework of "privacy as contextual integrity." In particular, we examine Nissenbaum's "Decision Heuristic" model, described in her most recent work on privacy (Nissenabum 2010), to see how it enables the contextual-integrity framework to respond to privacy challenges posed by new and emerging technologies. We then apply that heuristic device to questions surrounding one aspect of cloud computing -- viz., …


Cloud Computing Concerns In Developing Economies, Mathias Mujinga, Baldreck Chipangura Jan 2011

Cloud Computing Concerns In Developing Economies, Mathias Mujinga, Baldreck Chipangura

Australian Information Security Management Conference

Cloud computing promises to bring substantial benefits to how organizations conduct their businesses and the way their services reach out to potential consumers. Cloud computing is a welcome initiative for small businesses that cannot afford to invest in ICT infrastructure but need to benefit from the rewards of conducting business online. In developing economies, there are challenges that face cloud services providers and their consumers. Broadband network access was identified as the main essential service for a successful cloud computing offering. The objective of this paper is to give background information on the security issues in cloud computing, and highlight …
