WPA2-Enterprise networks authenticate clients through 802.1X using a RADIUS server. A common attack method described in CEH training is to create an evil-twin access point broadcasting the same SSID as the legitimate one. Combined with de-authentication frames, clients are forced off the real AP and automatically reconnect to the stronger rogue AP. This allows the attacker to capture authentication exchanges for later misuse, including credential harvesting or EAP-based downgrade attacks.
