In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.

本文系统地介绍了网络安全的概念、OSI及Internet的安全体系结构，并讨论了计算机网络面临的各种安全威胁；内部网络的安全问题是每个建网单位面临的最大问题，可以认为防火墙技术是解决网络安全的一个主要手段，本文研究了防火墙的原理及其实现手段；作为一种主动的防御措施，入侵检测系统作为网络系统安全的重要组成部分，得到了广泛的重视，TDS对计算机和网络资源上的恶意使用行为进行识别和响应，不仅检测来自外部的入侵行为，也监督内部用户的未授权活动；虚拟专用网技术的出现，为实现网络间的连接提供了快速安全但又相对便宜的手段，本文较深入的探讨了实现VPN的隧道技术，并对VPN的概念、功能、实现途径、基本构成、关键技术及发展前景等问题进行了全面论述；数据加密技术是网络安全核心技术之一，本文从数据加密算法、数字摘要、数字签名及数字证书等几方面简要介绍了数据加密技术，并分析用数字证书和数字签名实现网络安全的原理和过程；对安全协议的基本原理、主要特点进行了较为深入的研究，并就网络的安全性问题剖析了三种安全协议：IPsec协议、SLL协议和SET协议。

But, you get what you pay for - I am afraid sometimes even free wine is no bargain.

但也许便宜无好货–有时候即使有免费的酒喝可能也不见得占了便宜。

However, you get a bargain at the time of death, but after death it's no bargain. It's far more suffering than the other way of dying. You don't realize that when you're still a person, but when you are a ghost you know.

但是你死的时候便宜，死后了也是不便宜，还是比那个痛苦更厉害，不过人不知道，而鬼知道。

In other words, everything costs something and everything has to be paid for by someone; statements otherwise are ploys for gulling credulous people.

The consuming electronic product has already moved towards the era of the low gross profit now. In the market that is competed for in this way, consumer's demand for quality is higher and higher, and hope to require the cheap price to be bought. For electronic industry, it is a very great pressure, because will not only lower costs, but also improve the quality of the products. To electronic industry, the supplier has a great effect to the product quality. It's mean a lot of manufacturers just consider the low cost and neglect the quality supplied. This can cause quality failure cost, and has increased the cost. So, begin to have manufacturers to hope to gain the high quality like automobile industry. They want to carry out the quality management system ISO/TS16949:2002 of the automobile industry to improve quality and get the lower cost.

摘要 现在消费性电子产品已经走向了低毛利的时代，在这麼竞争的市场中，消费者对於品质的要求越来越高，且希望要求便宜的价格来购买，这对电子产业来说，是一个很大的压力，因为不只要降低成本，而且要提高产品品质；对电子产业来说，产品的品质往往掌握在供应商的手上，意思是说很多厂商只是一昧追求低成本而去忽略了供应的品质，这样反而会造成品质失败成本，而增加了成本，因此，开始有厂商希望可以做到像汽车产业那样的高品质，希望藉由汽车业的品质管理系统ISO/TS16949：2002的导入来提升品质、降低成本。

Not too cheap to meter , as Atomic Energy Commission chief Lewis Strauss said in a different context, but too cheap to matter .

并不是便宜得不用去计量，正如原子能委员会主席Lewis Strauss 以另一种方式所表述的，而是便宜得没必要去计较。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!

天啊，这是第二次你打败了我！
