Developing a Prototype for Role-Based Security Systems: A Template-Based Approach

This report explores a template-based methodology for constructing a prototype of role-based security systems. It introduces fundamental concepts of role-based security, including discretionary and mandatory access control, role hierarchy, and authorization. The approach is illustrated through a sample application, showcasing its design through class and use case diagrams. The report evaluates performance, usability, and lessons learned. This work is guided by a committee from the Department of Computing and Information Sciences at Kansas State University.
