Evaluate - peer review post - The paper Role-Based Access Control Models by Sandhu et al. (1996) continues to be highly relevant today because it has thousands of citations on Google Scholar. The main concept of role-based access control provides organizations with a flexible method to enforce security policies across both government and commercial systems. Organizations need flexible centralized access control systems more than ever because they continue to expand their operations through cloud computing and remote work and microservices adoption. System administrators can simplify user management through RBAC because they can group permissions into roles instead of assigning permissions individually. The system enables better least privilege access enforcement and separation of duties while minimizing insider threats and misconfigurations. The principles of RBAC appear in modern platforms including Microsoft Active Directory and AWS IAM and enterprise-level software like Oracle databases. The paper established fundamental access control models which remain active in modern cybersecurity and system architecture
