Role-Based Access Control
Role-Based Access Control (RBAC) is a security model that restricts system access to authorized users based on their assigned roles within an organization. It simplifies permission management by grouping users into roles (e.g., admin, editor, viewer) and assigning permissions to these roles rather than individual users. This approach enhances security, reduces administrative overhead, and ensures compliance with access policies in applications, networks, and systems.
Developers should implement RBAC when building applications that require fine-grained access control, such as enterprise software, SaaS platforms, or internal tools, to enforce security and prevent unauthorized data access. It is particularly useful in multi-user environments where permissions need to be managed efficiently, such as in healthcare, finance, or content management systems, to comply with regulations like HIPAA or GDPR. Learning RBAC helps in designing scalable and maintainable authorization systems.
