What protocol is associated with enterprise-mode Wi-Fi authentication?

Enterprise-mode Wi-Fi authentication typically utilizes protocols that ensure secure and scalable authentication methods in a corporate environment. PEAP, or Protected Extensible Authentication Protocol, is the correct choice because it creates an encrypted tunnel for authentication and supports the use of multiple authentication methods within that tunnel, often utilizing RADIUS servers for verifying credentials.

PEAP is widely used in enterprise networks because it enhances security by encapsulating another protocol (like EAP) within a secure TLS (Transport Layer Security) tunnel, which protects the user credentials during the authentication process. This layered security approach makes PEAP a preferred choice for organizations aiming for robust Wi-Fi security.

While RADIUS plays an integral role in enterprise Wi-Fi authentication by serving as the centralized authentication server, it is not a protocol on its own for authentication within the context of the wireless connection. Instead, it works alongside protocols like PEAP to facilitate the authentication process effectively.

TLS is a foundational technology that offers encryption and secure communication but does not directly define an authentication method specifically for wireless networks. LEAP, while an older authentication protocol specific to Cisco, is considered less secure compared to modern alternatives like PEAP, making it less suitable for enterprise environments that require stronger security measures.
