An access control system's primary task is to restrict access. RBAC also helps you to implement standardized enforcement policies, to demonstrate the controls needed for compliance with regulations, and to give users enough access to get their jobs done. Rules are integrated throughout the access control system. Role-based access control (RBAC) is a security approach that authorizes and restricts system access to users based on their role (s) within an organization. In such cases, RBAC and ABAC can be used together, with RBAC doing the rough work and ABAC complementing it with finer filtering. Based on least-privilege access principles, PAM gives administrators limited, ephemeral access privileges on an as-needed basis. This is critical when access to a person's account information is sufficient to steal or alter the owner's identity.
