Which authentication protocol is suggested to minimize masquerading attacks in WiFi?

PEAP, or Protected Extensible Authentication Protocol, is suggested to minimize masquerading attacks in WiFi environments due to its strong focus on security and encrypted communication. PEAP creates a secure tunnel between the client and the authentication server, protecting user credentials during authentication.

This protocol encapsulates EAP (Extensible Authentication Protocol) within a secure TLS (Transport Layer Security) tunnel, ensuring that sensitive information, such as usernames and passwords, is not sent over the air unprotected. By doing so, PEAP significantly reduces the chances of an attacker impersonating a legitimate user, which is a common tactic in masquerading attacks.

Additionally, PEAP supports the use of various authentication methods, enhancing flexibility while providing a robust defense against unauthorized access. This makes it a preferred choice in environments that require secure wireless connections, such as enterprise networks.

In contrast, other options like WPA (Wi-Fi Protected Access) and TLS, while providing certain levels of security, do not specifically focus on the protection of authentication processes in the same comprehensive manner as PEAP. WEP (Wired Equivalent Privacy) is an outdated security protocol that is known for its vulnerabilities and is not recommended for securing modern WiFi networks.
