The idea is that users are assigned roles based on their job function or responsibilities, and the roles are assigned the necessary permissions to perform their tasks. This approach reduces the complexity of access management by enabling administrators to modify permissions for groups of users instead of managing individual user-level permissions. RBAC also enhances security by enforcing separation of duties, meaning that a single user cannot have permissions that conflict with their role or create a security risk. By implementing RBAC, organizations can efficiently manage user access, reduce the risk of unauthorized access or misuse of sensitive information, and achieve regulatory compliance requirements.
