中文摘要

 隨著通訊和計算機技術的迅猛發展，計算機的網絡向世界各個角落延伸，網絡成為人們生活中不可缺少的部分。國家政府機構及企事業單位都在建立自己的網站。通過網絡樹立形象、開展業務，已經成為政府辦公，企業發展的重要手段。也有些犯罪分子可以很容易地利用即時通信軟件的便利性，在網絡談論不法內容、發泄對社會的不滿、造謠惑眾、散播不法消息，輕易地達到他們的所要的目的。如何使人們在享受網絡帶來的便捷和機遇的同時，能夠確保網絡的安全已是亟需解決的問題。
 本文的主要內容就是論述局域網網絡安全監控工具的設計和實現。首先，本文介紹了一些實現的基本原理，以及有關WinSock的網絡編程基本原理和sniffer技術，WinPcap 的包捕獲技術，為系統的設計和實現準備了一些理論基礎；然后講述了局域網網絡安全監控工具的一些關鍵技術，重點分析了屏幕監控技術和WinPcap 的包捕獲技術。
 本系統是C/S模式系統，實現的主要功能是客戶端進程通過請求服務器進程的服務，實現對服務器監控，監控的主要方式有：掃描主機是否在線，捕獲局域網內的數據包，直接執行和操作受控端的文件，操作受控制端的注冊表，監控受控制端計算機的屏幕，網絡流量監控，禁止瀏覽某些網站；系統是以Windows Vista為開發平臺，在Visual C++6.0環境下開發完成的。
關鍵詞：監控，屏幕監控，流量控制，數據包捕獲

 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
