Abstract: A method and apparatus are provided for detecting attacks on a data communication network. The apparatus includes a router with a mechanism for monitoring return messages addressed to an originating user system local to the router. The mechanism includes a message checker for identifying a return message of a specified nature and a rerouter for temporarily routing subsequent messages from the originating user system to the intrusion detection sensor.
