A detection-based defense to a wireless network. Elements of the infrastructure, e.g., access points or scanning-only access points, detect intruders by detecting spoofed frames, such as from rogue access points. Access points include a signature, such as a message integrity check, with their management frames in a manner that enables neighboring access points to be able to validate the management frames, and to detect spoofed frames. When a neighboring access point receives a management frame, obtains a key for the access point sending the frame, and validates the management frame using the key.
