As an open system, the enterprise has experienced a complex and developmental process from its foundation, expansion, maturity to its decadency. During the process, there is crisis anytime because of the external and internal circumstances' changes within the enterprise.

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。

Then the article starting from the activity, which relates the person with exterior nature,namely the human society work practice, elaborates the nature which worked as the foundation of humanity labor,and the human could not leave it and are bringing it into line with the nature as the work essential factor of labor process; The realistic nature similarly also cannot leave human as persons work creation, and this is the question of two aspects.The thesis has analyzed the work and natural relations in the agricultural society and in modern industry society ,and obtains the conclusion that the different ecology values can form under the different production method. This article criticizes disassimilation work in the capitalist society not only causes the disassimilation relationship between the human, but also creats the disassimilation which human and nature related, and proposes the communism society not only is the society in which the contradictory exploitation between human and nature is solved, and the contradictory relation between human and nature is also solved.

的结论；其次从人与外部自然相联系起来的是活动，即人类社会劳动实践出发，论述了自然界作为人类劳动的基础，人类须臾离不开它，人是把自然界作为劳动的要素而纳入自己的劳动过程的；现实的自然界作为人的劳动创造同样也离不开人，这一个问题的两个方面，并分析了在农业社会中劳动与自然的关系和近现代工业社会中劳动与自然的关系，得出在不同的生产方式下会形成不同的生态价值观的结论，批判了资本主义社会的异化劳动不仅造成了人与人之间关系的异化，还造成了人与自然之间关系的异化，提出共产主义社会不仅是人与人之间对立矛盾的剥削与被剥削关系真正解决的社会，也是人与自然之间破坏与被破坏的矛盾关系真正解决的社会的论断。
