WPA3 (Wi-Fi Protected Access 3) is a wireless security method that supports the majority of current Wi-Fi-capable devices without sacrificing security. It is backward compatible with WPA2 devices and offers enhanced encryption and authentication features. MAC filtering is another wireless security method, but it can be easily bypassed by spoofing MAC addresses. RADIUS (Remote Authentication Dial-In User Service) and TACACS+ (Terminal Access Controller Access-Control System Plus) are network authentication protocols, but they are not wireless security methods by themselves.
