Crack WPA2, raise an evil twin, and defend the air
Wi-Fi is the perimeter you can't see. Capture and crack a WPA2 4-way handshake, stand up an evil-twin rogue AP with a captive portal, run clientless PMKID and WPS attacks, and break WPA2-Enterprise EAP — each paired with the WPA3 / 802.1X / 802.11w defense that stops it.
