随着计算机网络的普及，网络安全问题越来越得到人们的重视。在确保网络安全和数据安全方面，有数据加密技术、智能卡技术、防火墙技术等，我们在这里主要研究的是防火墙技术。在这里，我们了解了防火墙的概念及它的分类，知道了什么是防火墙以及它在网络中起到了的作用。从防火墙的防范方式和侧重点的不同来看，防火墙可以分为很多类型，本文根据防火墙对内外数据的处理方法上，大致将防火墙分为包过滤防火墙和代理防火墙两大体系，并对这两种防火墙进行了对比。了解了防火墙的作用及它的优缺点，对防火墙的认识进一步的加深。然后介绍了防火墙三种基本实现技术：分组过滤、应用代理和监测模型。最后，了解了防火墙的基本元素及防火墙的三个典型结构。总之，我国目前使用较多的，是在路由器上采用分组过滤技术来提供网络安全的保证，对其它方面的技术还缺乏深入了解. 防火墙技术还处在一个发展阶段，仍有许多问题有待解决.

Answer 1

With the popularity of computer networks, the issue of network security has been more people's attention. In ensuring network security and data security, data encryption technology, smart card technology, firewall technology, we study here is the main firewall technology.

Then on three basic firewall Technology: packet filtering, application proxy and monitoring model. Finally, understand the basic elements of the firewall and the firewall three typical structure. In short, our country is the use of more, is used in routers, packet filtering technology to provide network security guarantees to other aspects of the technology that the lack of in-depth understanding. Firewall technology is still in a stage of development, there are still many problems remain to be solved.
