What authorization mechanism must all CANES devices and resources authenticate through?

The correct choice is based on the requirement that all devices and resources within the Consolidated Afloat Networks and Enterprise Services (CANES) environment authenticate through a specific authorization mechanism. Role-Based Access Control (RBAC) is designed to restrict system access to authorized users based on their roles within an organization.

In this context, RBAC utilizes the Identification, Authentication, and Authorization Service (IAAS) to ensure that users are granted access based on their specific roles and responsibilities. This is particularly important in a military or secure networks setting like CANES where the need to manage user access effectively, minimizing the risk of unauthorized access, is critical.

By implementing RBAC, organizations can streamline their administration of user rights and privileges, reduce the potential for human error in assigning access rights, and ensure compliance with security policies. This system allows for a more structured way to manage permissions, aligning user duties with appropriate data access levels.

The other options, while relevant in broader contexts, do not specifically match the established authorization mechanism for CANES devices and resources.
