Abstract
A method and system to mitigate an attack over the Internet includes collecting information related to a plurality of client IP addresses from a plurality of sources and analyzing the collected information to determine confidence scores for the plurality of client IP addresses. The method and system also include receiving network traffic from the Internet and limiting network traffic from a first subset of the plurality of client IP addresses characterized by a confidence score less than a first threshold. The method, and system further include determining a level of the network traffic and limiting network traffic from a second subset of the plurality of client IP addresses characterized by a confidence score less than a second threshold greater than the first threshold.
