Abstract

A method, apparatus, and program product are provided for protecting a network from intrusions. An offending packet communicated by an offending host coupled to a protected network is detected. In response to the detection, a blocking instruction is returned to the offending host to initiate an intrusion protection operation on the offending host, where the blocking instruction inhibits further transmission of offending packets by the offending host. At the offending host, a blocking instruction is received with a portion of an offending packet. The offending host verifies that the offending packet originated from the host. In response to the verification of the offending packet originating from the host, an intrusion protection operation is initiated on the host thereby inhibiting transmission of a subsequent outbound offending packet by the host.
