Final answer:
The technology that should be used instead of LEAP is PEAP (Protected Extensible Authentication Protocol), which provides a more secure encapsulation of the authentication process.
Step-by-step explanation:
The technology that should be used instead of LEAP (Lightweight Extensible Authentication Protocol) is PEAP (Protected Extensible Authentication Protocol). LEAP is an older authentication protocol that has been found to have several security vulnerabilities. PEAP was developed to address these vulnerabilities by encapsulating the authentication process within a secure TLS tunnel, providing an enhanced level of security.
While EAP (Extensible Authentication Protocol) is a framework for many different authentication methods, and RADIUS (Remote Authentication Dial-In User Service) is a networking protocol for authentication, authorization, and accounting, PEAP is specifically designed to provide more secure authentication for wireless networks over the original LEAP protocol. Lastly, 802.1x is an IEEE standard for network access control, which commonly uses EAP for the authentication process but is not an authentication method itself.
