Abstract: By analyzing the different characteristics of datagram of normal and abnormal network usage patterns, an intrusion recognition technique is present e d with neural network in this paper. Better performance can be gained by BP al go rithm with bias cell and internal recurrent. The result of simulation of port sc anner is also given.
