中文摘要
随着通讯和计算机技术的迅猛发展，计算机的网络向世界各个角落延伸，网络成为人们生活中不可缺少的部分。国家政府机构及企事业单位都在建立自己的网站。通过网络树立形象、开展业务，已经成为政府办公，企业发展的重要手段。也有些犯罪分子可以很容易地利用即时通信软件的便利性，在网络谈论不法内容、发泄对社会的不满、造谣惑众、散播不法消息，轻易地达到他们的所要的目的。如何使人们在享受网络带来的便捷和机遇的同时，能够确保网络的安全已是亟需解决的问题。
本文的主要内容就是论述局域网网络安全监控工具的设计和实现。首先，本文介绍了一些实现的基本原理，以及有关WinSock的网络编程基本原理和sniffer技术，WinPcap 的包捕获技术，为系统的设计和实现准备了一些理论基础；然后讲述了局域网网络安全监控工具的一些关键技术，重点分析了屏幕监控技术和WinPcap 的包捕获技术。
本系统是C/S模式系统，实现的主要功能是客户端进程通过请求服务器进程的服务，实现对服务器监控，监控的主要方式有：扫描主机是否在线，捕获局域网内的数据包，直接执行和操作受控端的文件，操作受控制端的注册表，监控受控制端计算机的屏幕，网络流量监控，禁止浏览某些网站；系统是以Windows Vista为开发平台，在Visual C++6.0环境下开发完成的。
关键词：监控，屏幕监控，流量控制，数据包捕获
Abstract
Along with the communication and computer technology's rapid development, computer's network extends to world each corner, accesses the net to become the people to live the essential part. The National government organization and the Enterprises and institutions are establishing own website. Through accesses the net to set up the image, the development service, already became the government work, the enterprise development important means. Also some criminal offender may use the immediate correspondence software's convenience very easily, in on-line discussion illegal content, gives vent to society's disaffection, fabricates a rumor deludes the people, the dissemination illegal news, serves the purpose which easily they want. How to cause the people while enjoys the network to bring convenient and opportunity, can guarantee that the network the security already was the question which needed to solve.
This article primary coverage is elaborates the local area network network security to monitor tool's design and to realize. First, this article introduced some realize the basic principle, as well as the related WinSock network programming basic principle and the sniffer technology, the WinPcap package capture technology, and realized for system's design has prepared some rationale; Then narrated the local area network network security monitors tool's some key technologies, selective analysis screen monitoring technology and WinPcap package capture technology.
This system is the C/S pattern system, realizes the major function is the client side advancement through the request server advancement service, realizes to the server monitoring, the monitoring fundamental mode includes: Scans the main engine whether online, catches in local area network's data packet, the direct execution and the operation are controlled the end the document, operates is controlled the end the registry, monitors is controlled the end computer's screen, the network current capacity monitoring, forbids to glance over certain websites; The system is as develops the platform take Windows VISTA, environment develops in Visual under the C++6.0 completes.
Keywords: Monitoring, screen monitoring, flow control, data packet capture
