What kind of access does a role-based access control (RBAC) system use?

Role-based access control (RBAC) systems utilize defined user roles with specific permissions to manage access to resources. In an RBAC framework, access rights are assigned based on the role a user has within an organization rather than on an individual user's identity or the identity of a device. This approach streamlines the process of managing permissions, as roles can encompass multiple users and specify what resources and actions are associated with each role.

For instance, a company may have predefined roles such as "Administrator," "Manager," and "Employee," each with distinct permissions that align with their responsibilities. An Administrator may have full access to all resources, while an Employee may only have access to certain applications and data necessary for their job functions.

This method is efficient because when a user's role changes, only their role assignment needs to be updated to alter their access rights, rather than modifying individual permissions. Such a system enhances security, simplifies access management, and ensures that users have only the necessary access to perform their duties while minimizing the risk of unauthorized access.
