Role-based access control is the authorization technique that is used to assign permissions and authorize a user based on job title or function. Role-based access control is a security method that defines roles for users or groups and assigns permissions for each role based on their responsibilities or tasks. Role-based access control simplifies the management of user access rights by allowing administrators to grant or revoke permissions based on roles rather than individual users.
