At the same time, the anti-attack ability of the system is also improved. Even if some analysis module cannot work, it does not affect other modules. The packet capture module is the base of entire system. At present, most NIDS develop their packet capture module based on libpcap library whose windows edition is winpcap. Allowing for capturing efficiency and self-determined intellectual property and cooperation of each module, we program protocol driver to capture packets. By following methods such as filter in driver and decrease packet copies between user mode and kernel mode, we enhance the capturing efficiency.

网络数据包采集模块是整个系统高效工作的基础，目前国内外的大多数网络入侵检测系统的数据采集模块，都是利用libpcap提供的函数库来实现，其在Windows下的版本为winpcap，考虑到采集效率、自主知识产权、采集模块与系统其他模块的配合等因素，我们采用自己编写协议驱动程序来采集数据包，并通过在驱动程序中实施过滤、减少数据包在用户态空间和核心态空间之间拷贝的次数等方法，提高采集的效率。
