When using RADIUS for WLC management access, which service is not provided?

RADIUS (Remote Authentication Dial-In User Service) is a client/server protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users connecting to a network service. While RADIUS is excellent for AAA functions, it does not inherently provide confidentiality for the data being transmitted over the network. Confidentiality, which ensures that data is not disclosed to unauthorized individuals, is typically achieved through encryption protocols like SSL/TLS, which would be implemented separately to secure the management session itself. Therefore, RADIUS itself does not offer confidentiality.
