DESIGN OF A ROLE BASED ACCESS CONTROL SYSTEM FOR MULTI USER ENVIRONMENTS

Multi-user environments have become an integral part of modern information systems, which include enterprise applications and cloud platforms and healthcare systems and educational portals. The system requires secure access control, which must work efficiently, because multiple users with distinct roles need to access shared resources at the same time. The traditional user-based access control methods become unmanageable because they require more resources to handle increased user and resource demands. The organization faces difficulties because it needs to protect its security standards while stopping unauthorized system entry. Role-Based Access Control (RBAC) provides a structured solution by assigning permissions based on predefined roles rather than individual users. In an RBAC system, roles represent organizational responsibilities, and users inherit permissions through their assigned roles. The access control system establishes controlled user access through this method which enables better security safeguarding together with lower operational demands. The design of an RBAC system focuses on defining users, roles, permissions, and their relationships while enforcing essential security principles such as least privilege and accountability. This article presents the design of a Role-Based Access Control system for multi-user environments which demonstrates its ability to scale and provide security advantages while serving as an effective solution for contemporary digital systems. The proposed approach provides a strong foundation for building secure, manageable, and efficient access control mechanisms.
