Wi-Fi Protected Access 2 (WPA2) provides users with a higher level of assurance that their data will remain protected by using which protocol?

Wi-Fi Protected Access 2 (WPA2), in its more secure Enterprise mode, implements the IEEE 802.1X standard for port-based network access control. This standard utilizes the Extensible Authentication Protocol (EAP) as its authentication framework. EAP provides a standardized transport for authentication messages between a client device (supplicant), the wireless access point (authenticator), and a central authentication server (e.g., RADIUS). This architecture allows for the use of various strong authentication methods, such as certificates (EAP-TLS) or credentials, providing a significantly higher level of assurance and centralized user management compared to the pre-shared key (PSK) model.

"IEEE 802.1X Port-Based Access Control

" states

"IEEE 802.1X uses the Extensible Authentication Protocol (EAP) [RFC 3748] to exchange authentication messages between the supplicant and the authentication server."

"WPA2-Enterprise

" states

"WPA2-Enterprise uses 802.1X/EAP for authentication. With 802.1X/EAP

a user must authenticate to the network before being granted access."
