Cloud computing is based on years of research on various computing paradigms. It provides elasticity, which is useful in the situations of uneven ICT resources demands. As the world is moving towards digitalization, the education sector is expected to meet the pace. Acquiring and maintaining the ICT resources also necessitates a huge amount of cost. Education sector as a community can use cloud services on various levels. Though the cloud is very successfully running technology, it also shows some flaws in the area of security, privacy and trust. The research demonstrates a model in which major security areas are covered like authorization, authentication, identity management, access control, privacy, data encryption, and network security. The total idea revolves around the community cloud as university at the center and other associated colleges accessing the resources. This study uses OpenStack environment to create a complete cloud environment. The validation of the model is performed using some cases and some tools.

<p><strong>BACKGROUND:</strong> Healthcare data are very sensitive records that should not be made available to unauthorized people in order for protecting patient's information security. However, in progressed technologies as cloud computing which are vulnerable to cyber gaps that pose an adverse impact on the security and privacy of patients’ electronic health records and in these situations, security challenges of the wireless networks need to be carefully understood and considered. Recently, security concerns in cloud computing environment are a matter of challenge with rising importance.</p><p><strong>OBJECTIVE:</strong> In this study a systematic review to investigate the security challenges in cloud computing was carried out. We focused mainly on healthcare cloud computing security with an organized review of 210 full text articles published between 2000 and 2015.</p><p><strong>METHOD:</strong> A systematic literature review was conducted including PubMed, Science direct, Embase, ProQuest, Web of science, Cochrane, Emerald, and Scopus databases.</p><p><strong>FINDINGS:</strong> Using the strategies described, 666 references retrieved (for research question one 365, research question two 201, and research question three 100 references).</p><p><strong>IMPROVEMENTS:</strong> Review of articles showed that for ensuring healthcare data security, it is important to provide authentication, authorization and access control within cloud's virtualized network. Issues such as identity management and access control, Internet-based access, authentication and authorization and cybercriminals are major concerns in healthcare cloud computing. To manage these issues<strong> </strong>many involved events such as Hybrid Execution Model, VCC-SSF, sHype Hypervisor Security Architecture, Identity Management, and Resource Isolation approaches<em> </em>have to be defined for using cloud computing threat management processes.</p>

Identity Management System

Today, cloud-based services and applications are ubiquitous in many systems. The cloud provides undeniable potential benefits to the users by offering lower costs and simpler deployment. The users significantly reduce their system management responsibilities by outsourcing services to the cloud service providers. However, the management shift has posed significant security challenges to the cloud service providers. Security concerns are the main reasons that delay organizations from moving to the cloud. The security and efficiency of user identity management and access control in the cloud needs to be well addressed to realize the power of the cloud. In this chapter, the authors identify the key challenges and provide solutions to the authentication and identity management for secure cloud business and services. The authors first identify and discuss the challenges and requirements of the authentication and identity management system in the cloud. Several prevailing industry standards and protocols for authentication and access control in cloud environments are provided and discussed. The authors then present and discuss the latest advances in authentication and identity management in cloud, especially for mobile cloud computing and identity as a service. They further discuss how proximity-based access control can be applied for an effective and fine-grained data access control in the cloud.

This article discusses the main security requirements for Web services and it describes how such security requirements are addressed by standards for Web services security recently developed or under development by various standardizations bodies. Standards are reviewed according to a conceptual framework that groups them by the main functionalities they provide. Covered standards include most of the standards encompassed by the original Web Service Security roadmap proposed by Microsoft and IBM in 2002 (Microsoft and IBM 2002). They range from the ones geared toward message and conversation security and reliability to those developed for providing interoperable Single Sign On and Identity Management functions in federated organizations. The latter include Security Assertion Markup Language (SAML), WS-Policy, XACML, that is related to access control and has been recently extended with a profile for Web services access control; XKMS and WS-Trust; WS-Federation, LibertyAlliance and Shibboleth, that address the important problem of identity management in federated organizations. The article also discusses the issues related to the use of the standards and open research issues in the area of access control for Web services and innovative digital identity management techniques are outlined.
