An apparatus and method for secure, automated response
to distributed denial of service (DDoS) attacks are
described. The method includes notification of a DDoS
attack received by an Internet host. Once received by an
Internet host, the Internet host establishes security
authentication from an upstream router from which the
attack traffic, transmitted by one or more host
computers, is received. The Internet host then transmits
filter(s) to the upstream router generated based upon
characteristics of the attack traffic. Once installed by the
upstream router, the attack traffic is dropped to terminate
a DDoS attack. In addition, the router may determine
upstream router(s) coupled to ports from which attack
traffic is received, and securely forward the filter(s) to
the upstream routers as a routing protocol updated in
order to drop the attack traffic at a point closer to a
source of the DDoS attack.
