A system and method of transmitting a DDoS, or distributed denial of service, signature from an intra-network to an internet is presented. The method includes identifying a DDoS signature and employing an inter-domain routing protocol configured to enable-operational information to be exchanged between nodes. The DDoS signature is embedded as payload of the standards-compliant inter-domain routing protocol. The step of embedding occurs within a network. The embedded DDoS signature is then sent from the network to an internet node outside of the network. The method further includes applying the DDoS signature to enable the internet nodes to filter packets matching the DDoS signature.
