Abstract
A method, an apparatus and a program for detecting spoofed Internet Protocol (IP) traffic directed to a network having a plurality of autonomous systems (AS) is provided. The method comprises receiving an incoming packet through an AS, the incoming packet containing a source IP address and a destination IP address, acquiring a corresponding source and destination IP address prefixes, converting the corresponding source and destination IP address prefixes into a source AS number and a destination AS number, determining if the incoming packet arrived from an unexpected source based upon the corresponding destination IP address prefix and the converted source and destination AS number using an unexpected pair tuple table generated from network routing information and generating an alert indicating that the incoming packet is not allowed to enter the network.
