Rule-based access control can also be a schedule-based system as you can have a detailed report that how rules are being followed and will observe the metrics. Role-based access control grants access privileges based on the work that individual users do. Labels contain two pieces of informationclassification (e.g., top secret) and category (e.g., management). Constrained RBAC adds separation of duties (SOD) to a security system.
