Abstract
A method, system and computer-usable medium are disclosed for performing an automated anti-spoofing configuration operation, comprising: determining whether a source address of an internet protocol (IP) packet is allowed by a receiving interface of a firewall; determining whether the IP packet comprises a multicast packet when the IP packet is allowed by the receiving interface of the firewall; replacing the source address with a rendezvous point address; using the rendezvous point address to determine whether routing path information associated with the multicast packet matches information stored within a multicast routing information base for the receiving interface of the firewall; and, identifying the multicast packet as spoofed when the routing path information associated with multicast packet does not have corresponding information stored within the multicast routing information base.
