Abstract: Role-Based Access Control (RBAC) is accepted as the most commonly used access control policy; however, it is mainly used during the development of new software systems. In this paper, an approach to reengineering RBAC into legacy systems by applying program transformation is proposed. Wide Spectrum Language (WSL) and MetaWSL are extended. Transformation rules, algorithm and operations for further authorisation management are defined to support access control reorganisation. A case study is demonstrated on a prototype tool FermaT-based Access Control Reorganisation (F-ACR). The result shows that it is a feasible and promising approach to enforcing RBAC in legacy systems.
Keywords: access control policy; RBAC; role-based access control; program transformation; legacy systems; software reengineering.
