【摘要】：随着IT技术的快速发展，计算机已经深入企业生产中各个环节，企业信息化也成为热门话题。信息化已成为企业获取竞争优势的最佳选择。各企业广泛应用局域网实现内部资源共享展开日常工作。近年来，随着企业局域网的规模日益庞大，企业从计算机、服务器等硬件设备大量投入使用获利的同时也面临着前所未有的三大威胁:企业核心材料和图纸泄密情况严重、企业核心资产白白丢失无法统计、因员工上网频频造成企业局域网中毒瘫痪。现在，如何管理好企业的局域网己成为各大企业管理者重视的问题和各企业网络管理员所面临的挑战。网络是把双刃剑，在加速信息交流、推动经济发展的同时，其负面影响也开始显现。各种反动组织和罪恶势力利用互联网宣扬和传播邪教、色情、暴力、赌博等内容，以网络为工具进行各种犯罪活动，从而使网络上的虚假、黄色、反动内容逐渐增多。这些都已经在社会上造成了消极影响，损害了网络的健康发展。团此，如何管理网络用户尤其是青少年学生对互联网访问，使其免受非友善信息的侵蚀，而且又不影响用户对网络的正常访问，越来越引起人们的关注。根据对企业局域网现状分析，结合目前流行的企业局域网监控软件的考察，本文主要研究如何在现有域管理基础上构建一套较为实用的局域网监控软件系统以适应互连网时代企业局域网对计算机硬件、软件、员工网络行为监控管理的需要。本文重点研究了在Windows操作系统下对文件进行实时监控技术的方法，实现了利用FileSystemWatcher类在Windows系统中进行文件监控；介绍FileSystemWatcher类在系统监控模块中的应用以及使用方法和它的一些优点和缺点，并且提出了解决方法。利用Visual Studio的软件本地化技术开发了软件的维汉两种版本。按照windows消息机制，通过利用Windows API和钩子技术获取用户在计算机上的操作行为。研究了数据库访问管理技术，实现了ADO．NET数据库访问技术在Windows系统中对文件进行实时监控的技术和方法。并研究和实现了计算机不良信息过滤技术和方法。提出了基于关键词的不良信息过滤方法以及它在网站内容过滤，搜索引擎过滤中的应用。实现了网址过滤，应用程序过滤功能。最后进行软件测试确保本系统的软件质量。本系统能够监控和详细记录用户的文件操作行为，有效阻止用户访问的不良信息网站，禁止运行工作无关的应用程序。为了验证软件的实际应用，软件经过打包部署到“新疆美乐蒂文化传媒有限公司”的工作机上，并对员工在工作机中的操作行为进行一周时间的监控测试。测试结果表明，，本文提出的系统监控技术在监控的全面性，有效性和软件的稳定性方面都达到了实用化的程度。而且软件的实用性得到了该企业领导的认可和好评。
[Abstract]:With the rapid development of IT technology, the computer has penetrated into all aspects of enterprise production, enterprise informatization has become a hot topic. Informationization has become the best choice for enterprises to gain competitive advantage. All enterprises widely use local area network to realize internal resource sharing to carry out daily work. In recent years, with the increasingly large scale of the enterprise local area network, enterprises are making a lot of profit from the computer, server and other hardware equipment. At the same time, they are also facing three unprecedented threats: the leakage of the core materials and drawings of the enterprise is serious. Enterprise core assets lost in vain can not be counted, because the staff frequently causes enterprise LAN poisoning paralysis. Now, how to manage the local area network (LAN) of enterprises has become an important problem for the managers and the challenges faced by the network administrators. Network is a double-edged sword, which accelerates information exchange and promotes economic development. All kinds of reactionary organizations and evil forces use the Internet to promote and spread cults, pornography, violence, gambling, and so on, and use the Internet as a tool to carry out various criminal activities, thus making the contents of the network false, yellow, and reactionary gradually increase. These have already caused the negative influence in the society, harmed the healthy development of the network. Therefore, how to manage network users, especially young students' access to the Internet, so as to avoid the erosion of unfriendly information, without affecting users' normal access to the network, has attracted more and more attention. According to the analysis of the present situation of the enterprise local area network, combined with the inspection of the popular enterprise local area network monitoring software, This paper mainly studies how to construct a set of practical LAN monitoring software system based on the existing domain management to meet the needs of computer hardware, software and employee network behavior monitoring management in the enterprise LAN in the Internet era. This paper focuses on the method of real-time monitoring of files under Windows operating system, and realizes the file monitoring in Windows system by using FileSystemWatcher class. This paper introduces the application of the FileSystemWatcher class in the system monitoring module and its usage, its advantages and disadvantages, and puts forward some solutions. Software localization technology of Visual Studio is used to develop Uighur and Chinese versions of software. According to the windows message mechanism, the operation behavior of the user on the computer is obtained by using the windows API and hook technology. This paper studies the technology of database access management and realizes the technology and method of real-time monitoring of files in Windows system by ADO.NET database access technology. The technology and method of computer bad information filtering are studied and realized. This paper presents a keyword based bad information filtering method and its application in web content filtering and search engine filtering. Web site filtering, application filtering function. Finally, software testing is carried out to ensure the software quality of the system. This system can monitor and record the user's file operation behavior in detail, effectively prevent users from visiting bad information websites, and prohibit the running of work-related applications. In order to verify the practical application of the software, the software is packaged and deployed to the working machine of "Xinjiang Melody Culture Media Co., Ltd." and the staff's operation behavior in the machine is monitored and tested for one week. The test results show that the system monitoring technology proposed in this paper has reached a practical level in terms of its comprehensiveness, effectiveness and software stability. And the practicability of the software has been recognized and praised by the enterprise leaders.
