What is Role Based Access Control (RBAC)?

Role-Based Access Control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within an organization. RBAC employs predefined roles and permissions associated with those roles to determine access rights. Instead of assigning permissions directly to users, permissions are assigned to roles, and users are then assigned to specific roles. This simplifies access management and improves security by ensuring that users only have access to the resources necessary for their job functions.
