Abstract
An exemplary apparatus for mitigating a distributed denial-of-service (DDoS) attack includes a controller configured: to receive an output signal from a detector in a networked computing system, the output signal indicating a probability of a DDoS attack based at least in part on a threat level corresponding to an Autonomous System Number (ASN) associated with a source Internet Protocol address of received data packets when a volume of the received data packets exceeds a prescribed threshold value; to obtain action information correlating a specific ASN to at least one corresponding action for mitigating a DDoS attack; and to generate at least one control signal for initiating at least one action for mitigating the DDoS attack as a function of the obtained action information. The apparatus further includes at least one mitigation device for performing at least one action for mitigating the DDoS attack in response to the control signal.
