  • System and method for mitigating distributed denial of service attacks
    Patent number: 10616271
    Abstract: A method and associated system for mitigating a Distributed Denial of Service (DDoS) attack on a target device including, receiving a plurality of data packets at a mitigation device, counting a number of occurrences of each destination address signature within each of a plurality of consecutive data packet windows, classifying each data packet window of the plurality of consecutive data packet windows as a potential attack window if the number of occurrences of any one destination address signature within the data packet window exceeds a destination address signature threshold value. The method further includes, determining a total number of potential attack windows within a sliding time window and limiting the transmission of the plurality of data packets from the mitigation device if a total number of potential attack windows within the sliding time window exceeds a potential attack window threshold value.
