Role-Based Access Privileges in a Complex Hierarchical Setup

Abstract

Role-Based Access Control (RBAC) is a widely adopted access management framework that ensures users receive appropriate permissions based on predefined roles rather than individual assignments. In complex hierarchical setups, organizations face challenges such as privilege accumulation, dynamic role transitions, and evolving security threats. This paper explores the extension of RBAC into hierarchical models, enabling role inheritance and structured access control propagation. Additionally, dynamic role assignment, context-aware access policies, and separation of duties (SoD) are examined as essential mechanisms to enhance security and operational flexibility. By integrating permission propagation techniques, access control lists (ACLs), and delegation mechanisms, enterprises can achieve a balance between security and operational efficiency. The principles of least privilege and user-role mapping strategies are also discussed to ensure scalable and secure access control implementation. This research highlights best practices and future directions, including AI-driven analytics and zero-trust architectures, to enhance RBAC frameworks in large organizations.
