Management frames: unauthenticated in WPA2

802.11 defines three frame classes: management (beacons, auth, association), control (ACK, RTS/CTS), and data. Management frames in WPA2 are unauthenticated — any attacker with a WiFi adapter can forge a deauthentication frame with a spoofed source MAC.

The victim's device has no way to verify the frame came from the real AP and disconnects immediately.
