摘要: A method and apparatus for preventing denial of service type attacks on data networks is described. The involves scanning the contents packets flowing over network using a traffic flow engine. are reordered reassembled then payload scanned to determine whether they conform predetermined requirements. Data which do not reorder or reassemble correctly requirements may be dropped. Dropping prevent attack exploit bugs in TCP/IP implementation shortcomings specification engine further operable associated with validated flows. Those flows assigned higher priority while those low priority, occupy no more that maximum available bandwidth. Assigning non-validated brute force designed clog networks.
