摘要
从应用层网关技术入手,深入探讨利用WinSock2SPI进行网络内容访问控制的方法,设计并实现一种基于Windows系统和浏览器无关的网页有害信息过滤系统,为网络安全技术的发展提供一个新的思路.
From the application of layer gateway technique, deep discussion was made on the approach of using WinSock 2 SPI to control surfing the Internet. A harmful message filter system was designed based on windows system irrelevant with explorers. It offers a new thought for researchers of safe techniques of network.
