Vol. 13  No. 6  pp. 92-97


As the demand for data and information management increases, there is also a critical need for maintaining the security of the databases, applications and information systems. Data and information have to be protected from unauthorized access as well as from malicious corruption. With the advent of the web it is even more important to protect data and information as numerous individuals have access to this data and information. Therefore we need effective mechanism to secure the information from unauthorized access in semantic web. Role Base Access Control Model (RBAC) is a traditional access control model & has some pros and cons. To overcome the limitations of RBAC, Attribute Base Access Control Model (ABAC) has been introduced. ABAC proved beneficial and secure over RBAC but it has higher complexity. Both models are not a fine grained access control model. To overcome the limitations of both these models, we have proposed a Hybrid Access Control Model (HACM). This is a model which can overcome most of the limitations of RBAC and ABAC. It can be proved a fine grained access control model. It is a combination of RBAC and ABAC systems. In this paper first we have an introduction of RBAC and ABAC to know the problems with both of them. Then we proposed architecture of HACM followed by its basic approach. We will have an overview of the functioning of HACM step by step which will be expressed by XACML architecture. After that we will have the comparison of RBAC and ABAC with HACM with some points of issues.
