A dynamic self-learning efficient intrusion detection model was proposed based on inductive reasoning.Ap-plying the method of inductive reasoning into intrusion detection
an incremental inductive reasoning algorithm for intru-sion detection was proposed.This model produced by this algorithm can make self-learning over the ever-emerged new network behavior examples and dynamically modify behavior profile of the model
which overcomes the disadva-ntage that the traditional static detecting model must relearn over all the old and new examples
even can not relearn because of limited memory size.And at the same time
the learning efficiency and detecting efficiency of intrusion detection model are improved greatly.
