Abstract
An ingress point receives a packet flow from a first communication device. The ingress point copies the packet flow, transmits the packet flow to an egress point over a network path, and processes the copy to determine if the packet flow represents a security event. If the packet flow represents a security event, the ingress point transmits a blocking instruction to the egress point over an alarm link and the egress point blocks the packet flow representing the security event. If the packet flow does not represent a security event, the egress point transmits the packet flow to a second communication device.
