What does Role-Based Access Control (RBAC) do in CANES?

Role-Based Access Control (RBAC) is a critical component of information security in systems like CANES, particularly due to its focus on controlling access based on user roles within an organization. By defining various roles and their corresponding permissions, RBAC ensures that users only have access to the information and functionalities necessary for their job responsibilities.

This model streamlines user management and enhances security by assigning permissions to roles rather than individuals. For example, a system administrator might have comprehensive access to configure settings, while a regular user may be restricted to viewing data only. Such an approach minimizes the risk of unauthorized access to sensitive information and helps maintain data integrity by preventing users from performing actions outside their defined roles.

The other choices do not align with the principles of RBAC. Unrestricted access would compromise security, allowing all users to access sensitive information indiscriminately. Enabling anonymous access poses significant risks, as it provides access without any verification of identity, which is contrary to the premise of RBAC. Likewise, only restricting access to guest users fails to recognize the broader application of roles across all user types, limiting the utility of the RBAC model. Therefore, the correct understanding of RBAC within CANES emphasizes its role in controlling and restricting system access based on user
