Which access control model is based on the roles individuals have within an organization?

Role-Based Access Control (RBAC) is grounded in the premise that access permissions are assigned to roles rather than to individual users. In an organizational context, this approach means that users are assigned to specific roles that correspond to the duties they perform. Each role is associated with a set of permissions that define what resources and actions a user in that role can access.

This model simplifies the management of user permissions, especially in large organizations. For instance, if multiple users share the same responsibilities and require the same access rights, they can be assigned to the same role. When a user's job changes or they leave the organization, the role can be updated or removed without needing to reconfigure individual permissions for each user.

In contrast, the other access control models mentioned are quite different in their approach to managing permissions. Mandatory Access Control (MAC) relies on a system of strict policies that dictate access rights based on classification labels, such as security levels. Discretionary Access Control (DAC) allows users to control access to their own resources, giving them the discretion to grant permissions to others. Attribute-Based Access Control (ABAC) governs access based on a combination of attributes (user, resource, environment), making it more flexible but also more complex. Each of these
