摘要：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. Themethod includes classifying the client as a top talker based on the number of requestsbeing greater than the top talker threshold and identifying, for the client, additionalrequests being transmitted to the server. The method also includes determining whethera 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 serverif the number of additional requests that matches one or more attack patterns is greaterthan a first threshold.
