Security for Cross-Tenant Access Control in Cloud Computing

Abstract

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.
