This kind of investigations have acquired some accomplishments at present , but much of these accomplishments were limited to resolve certain frondose application using certain fixed network model and were far from satisfying the minimizing forecasting faults demands of ids improving . the purpose of this theme is to establish a multi - net - model and make it generally applicable during the arithmetic realization process to content all application demands and thus minimize forecasting faults in the end of this article applying the advanced bp network to the es in ids minimized the false forecasting , further more it discussed the process of using visual c + + to realize these networks 目前，这方面的研究已有了部分成果，但大多只局限于应用一种固定的网络模型来解决某一具体的应用，还远远不能满足入侵检测漏报和误报率高的问题，本文的研究目的就是要建立一种灵活的网络模型，并在算法实现过程中使其具有通用性，以满足各种应用的需要，尤其是使入侵检测的漏报率和误报率趋于最小化。
