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。

Through the comparative analysis between the functions of the government"s'role in establishing a social security system in Britain, the US, Germany, Japan and other countries and Chinese government"s absence from their duties in establishing rural social security, we know, under the socialist market economic conditions, the government should bear the basic responsibilities in establishing the rural social security system, just to build a basic framework of the rural social security system adapted to the level of economic development, to establish a rural social security management system, to bear national financial responsibility in establishing the rural social security and promote mufti—dimensionally raising funds, to establish a rural social security monitoring mechanism, to establish a rural social security law system, to create external environment of the rural social security system, and so on.

在英、美、德、日等国构建社会保障制度中政府职能的角色定位与我国农村社会保障政府缺位的比较分析中，我们得出，在社会主义市场经济条件下，构建农村社会保障体系中政府应承担的基本职责，即构建和经济发展水平相适应的农村社会保障制度的基本框架，建立健全农村社会保障管理体制，承担国家对农村社会保障的财政责任并推动多渠道筹集资金，建立健全农村社会保障的监管机制，推动农村社会保障的法律体系建设，创造农村社会保障制度建设的外部环境等等。在当前的条件下，我国政府应着手采取现实可行的具体措施来履行其职能、推进我国农村社会保障体系的建设。

Currently it still exists many problems in Social Security System, such as incomplete legal institutions of social security, incapacious scope of security coverage, insufficient social security funds, disordered department functions and third sector's laggard development in social security system even though we have achieved obvious fruits in the reform of Social Security System, relatively increased the scale and level of social security too.

But our country's present social security system actually has the hindrance function to the occupation mobility, the main performances are as follows: Two units social security system, the unequal tax revenue system in the social security, social security singleness in view of the impoverished social class, hardly carried and transferred characteristics of social security system , ignoring benefits protection of mobile staffs, lack of social security legislation , slow development of service system of social security ,lack of policies and measures on promoting regional motilities insocial security system.

但是，我国现行的社会保障制度却对职业流动有着一定的阻碍作用，主要表现为：二元的社会保障体系的存在，社会保障体系的便携性、可转移性较差，忽视流动职工的利益保护，社会保障立法的缺失，社会保障服务体系发展缓慢，社会保障中税收体系的不平等，针对贫困阶层的社会保障单一，社会保障体系缺少促进区域流动的政策与措施等方面。
