Role-Based Access Control (RBAC)

Role-Based Access Control (RBAC) is an access management model that assigns permissions to users based on their roles within an organization. Instead of granting permissions directly to users, RBAC groups them into roles, ensuring efficient and scalable access control. Key elements include roles (e.g., admin, manager, user), role mapping (assigning users to roles), composite roles (roles that inherit permissions from other roles), and permissions (actions allowed for a role). RBAC simplifies access management, enforces least privilege, enhances security compliance, and reduces misconfiguration risks. In Keycloak, RBAC is implemented through realm roles, client roles, role mapping, and role-based policies, supporting fine-grained access control. RBAC is also a key component of the Zero Trust model, ensuring strict, role-based access restrictions.
