Abstract
In a network system having a plurality of devices communicating via a network, a method and system for providing an emergency signal is provided. In one embodiment, a device is malfunctioning if the device continuously transmits data to the network without proper authorization. Another properly functioning device transmits the emergency signal via an auxiliary channel to the malfunctioning device. The auxiliary channel is a separate channel supporting the transmission of the emergency signal. The malfunctioning device receives the emergency signal and disables itself in response to this signal.
