The processor may determine whether one or more of the response messages received from the device is an appropriate response or an inappropriate response to the fabricated message. In response to determining that a response message is an inappropriate response, the processor may determine that the device is an illegitimate base station. In response to determining that the device is an illegitimate base station, the wireless device may perform a protective action.
