Abstract

Software-as-a-Service (SaaS) is a new approach to software development that is distinguished by its multitenancy architecture and ability to provide flexible customization to individual tenants. Multi-tenancy is at the core of SaaS as it allows users (tenants) and providers the opportunity to fully exploit the full potential of cloud computing. However, due to multi-tenancy, access control has become a critical component in the development of SaaS systems, particularly for limiting cross-tenant access to resources. It’s one of the most important aspects of computer security and the ability to manage access to a SaaS system is a critical security problem that must be addressed. This research describes an improved version of Hierarchical Access Control Model (HRBAC) model called SAMRDT (SaaS Authorization management Resource Directed tree) which is based on resource directed tree. It combines the benefits of the ABAC and RBAC access control models and adds effective authorization management to the SaaS access control architecture. As part of our research work, a prototype system based on the model was implemented to evaluate the performance. We also specified a set of metrics that will be used to quantitively and objectively evaluate the performance of SAMRDT model for authorization management and permission filtering in SaaS.
