In the end, we summarize the thought features of post-experientialism philosophy of social science, and conclude the main object, which include breaking the unity of science of positivism, the wholism of science method, and overturn the authority of science. In fact, the post-experientialists look the science as society, history, culture, system, organization, and they are in the same position.

最后对后经验主义社会科学哲学的思想特征作出了总结，分析了其主要目标就是要打破实证主义的科学统一观、科学方法的整体论观念，推翻自然科学具有权威性和普遍有效的解释与预测功能等信仰，事实上也就是要祛除实证主义的科学神化观，转而将科学的理性和逻辑，看作与科学的社会、历史、文化、制度、组织等外在因素具有同等的地位。

During the "fight" against the pseudo-science, the news media mainly act as "fighters", firing vigorously against the pseudo-science, but sometimes they act disgracefully as "drivers", driving the pseudo-science forward unconsciously, which make the pseudo science, under the cloak of science, run rampantly at the same time.

在与伪科学的斗争中，新闻媒体主要扮演了&斗士&角色，向伪科学猛烈开火，但有时也扮演了不光彩的为伪科学抬轿的角色，致使伪科学披着科学的外衣泛滥成灾。

Taking the culture of the post modern philosophy as the background, taking the reverting of psychologism and the explosive growth of computer science and cognitive science as the preconditions, especially after the pendent discussion between science realism and criticism realism, the trend of naturalism philosophy of science presented itself.

在后现代哲学文化的大背景中，在心理主义的复归和计算科学与认知科学的迅速发展的前提下，特别是在科学实在论和反实在论的悬而未决的争论之后，自然主义的科学哲学思潮出现了。

According to introducing, the meeting after these baleful trojan programs affect tube-shaped part of computer science department undertakes to the system of a lot of destroy, be like: Without the license of computer user bowdlerism or it is file of the mass data in replacing interconnected system of computer science department, cause the important data in maintaining existence system to the file is lost or be distorted.

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。
