RBAC security in DBMS
Role-Based Access Control (RBAC) is a widely used access control mechanism in database systems. RBAC provides a flexible and scalable approach to managing access permissions by associating users with roles and defining the privileges associated with each role. We introduced access control back in Chapter 7 when we discussed authentication and authorization. Let’s explore RBAC in the context of database systems.
