Role-Based Access Control (RBAC) is a user authorization method that assigns access permissions based on users' roles within an organization, offering a secure and efficient way to protect sensitive information. Originating in the 1970s and refined into an industry standard by 2004, RBAC remains a prevalent access control model, projected to grow significantly in market value. The system's central concept revolves around roles that dictate user permissions, simplifying access management and aligning with job functions. RBAC models range from traditional, constrained, to hierarchical forms, each offering varying degrees of restriction and permission levels. Compared to other access control models like ReBAC, ABAC, RuBAC, MAC, and DAC, RBAC strikes a balance between security and accessibility, making it suitable for diverse business needs. Key benefits include enhanced security, regulatory compliance, user-friendliness, reduced IT workload, scalability, organizational transparency, and cost savings. Implementing RBAC involves assessing organizational needs, defining roles and permissions, establishing policies, mapping roles to users, and testing the system. Tools like Descope simplify the integration of RBAC, ReBAC, and ABAC into applications, enabling efficient role management and enhancing security without extensive in-house development.
