  • Techniques for automatically mitigating denial of service attacks via attack pattern matching
    Patent number: 10193911
    Abstract: A method for mitigating a denial of service attack includes determining, for a client, a number of requests being transmitted to a server and determining, for the client, that the number of requests for a time period is greater than a top talker threshold. The method includes classifying the client as a top talker based on the number of requests being greater than the top talker threshold and identifying, for the client, additional requests being transmitted to the server. The method also includes determining whether a number of the additional requests matches one or more attack patterns and preventing one or more of the additional requests from being transmitted to the server if the number of additional requests that matches one or more attack patterns is greater than a first threshold.
