Security for Cross-Tenant Access Control in Cloud Computing

Cloud computing is becoming a de facto standard for most of the emerging technology solutions. In a typical cloud environment, various tenants purchase the compute, storage resource, and would be sharing the resource with other tenants. Sharing of the resources among various tenants is not popular due to the security concerns. There are few solutions that try to solve the security problem of resource sharing among tenants. Having a trusted mediator between multiple tenants is one of the methods. Few research papers have been written, and this chapter attempts to enhance one of the published solutions: Cross-tenant access control model for cloud computing. Most of the existing research papers explore the theoretical way to solve the problem. This project develops a working prototype and proves how resource sharing can be achieved. This research develops the concept of resource sharing activation, where the resource can be shared with multiple cloud tenant and the deactivation where the shared resources can be removed from the shared resource pool.

This article describes how nowadays, cloud computing is one of the advanced areas of Information Technology (IT) sector. Since there are many hackers and malicious users on the internet, it is very important to secure the confidentiality of data in the cloud environment. In recent years, access control has emerged as a challenging issue of cloud computing. Access control method allows data accessing of an authorized user. Existing access control schemes mainly focus on the confidentiality of the data storage. In this article, a novel access control scheme has been proposed for efficient data accessing. The proposed scheme allows reducing the searching cost and accessing time, while providing the data to the user. It also maintains the security of the user's confidential data.

Community Cloud

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.

Access control technology protects cloud from being accessed illegal. However, traditional access control technology cannot meet the new features of the cloud environment. In order to improve the deficiency of the current multi domain access control in timeliness and flexibility. This paper put forward a dynamic access control policy on the basis of task driving idea. New method combined the advantage of RBAC and task driving model, joined with limit aging and real time strategy synthesis. Comparative trial show that new policy had an advantage in flexibility and availability of multi-domain access control model.
