SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT TO AVOID SERVER OVERLOAD BY CONTROLLING HTTP DENIAL OF SERVICE (DOS) ATTACKS

摘要

A system, method and computer program product for controlling a denial of service attack on one or more servers. The method involves intercepting, via an interface unit, a client request for information from the server; determining, by the interface unit, whether the client request is a valid request via a challenge-response mechanism (308); and forwarding the client request to the server (312) if the client request is a valid request (310). The client request may be an HTTP request. The challenge-response mechanism involves forwarding an executable response to the client; and receiving the client request with some additional verifiable information if the client request is a valid request.
