The traditional role-based access control (RBAC) model plays a crucial role in permission management but faces challenges in Web applications

such as lack of resource definition

permission explosion

and permission leakage. To overcome these limitations and enhance the precision and flexibility of permission management

a role-resource based access control (R-RBAC) model was proposed

which introduced resource hierarchy on top of RBAC

effectively addressing the shortcomings of the traditional model. A detailed analysis of the limitations of the traditional RBAC model in Web development was provided

the importance of the R-RBAC model was discussed

and the design of the new model was elaborated. Through practical case studies

the advantages and application prospects of the R-RBAC model in permission management were demonstrated. The research shows that the R-RBAC model not only resolves the issue of permission explosion by enabling dynamic configuration and automatic assembly of permissions but also excels in permission auditing and tracking

significantly facilitating permission management. This study delves into the design and practical application of the role-resource based access control model

highlighting its importance in improving the precision and flexibility of permission management. Future research can further optimize the R-RBAC model and explore its applications in other domains to achieve more efficient and secure permission management.
