1、 内网监控论文：公安内部网络安全监控系统管理系统的设计与实现【中文摘要】公安内网管理监控系统已经在全国得到了部署和使用,一些现成的商业或者组织研制的监控系统已经能很好的解决了“一机两用”问题和公安内网客户端安全管理等关键问题。课题研究开发了一款简易初步的局域网监控系统,适合于地市级单位使用,以节约成本。论文首先对目前的内网使用安全状况及其原因分析做了简要介绍,并介绍了课题研究的背景,提出了本课题的研发内容。其次,对系统研发过程中所用到的数据库知识、开发环境知识进行了介绍,为后续的描述做了铺垫。随后,对系统的用户需求进行了详细的分析,并设计了各个功能的用例。在通过对用例的初步分析的基础上,对系统
2、进行了概要设计,得到了系统框架结构与类结构。第四章则重点阐述了系统各个模块的详细设计。最后,讲述了系统的实现与测试方案设计。本研究实现了如下模块:1)检测和发现网络中存在的计算机通过MODEM,ADSL,双网卡及其离线方式等设备接入网络行为。2)记录各种非法上网的计算机信息,如上网时间,持续时间,客户端地址,计算机的IP地址,MAC地址等。3)详细记录非法上网计算机的计算机名称,单位,上网方式(代理,拨号)。4)便捷的查询设计功能,多种条件查询支持对一机两用信息进行信息查询统计。5)能够将本级监控系统管辖范围内的监控信息以数据库形式分类存储并上报,并实现监控或者病毒信息发布平台,实现数据上传邮
3、箱备分。本文所设计的内网监控管理信息平台特点如下:1)本文所构建的监控平台采用服务器/浏览器(B/S)框架构建系统,在服务器端以ACCESS和SQL Server 2000作为数据库服务器提供了数据库服务功能。2)本系统设计采用面向对象的分析和设计策略,用了三层架构的框架进行开发,使各模块的类结构非常清晰。在数据库设计方面,使用了数据关系图,比较直观、易懂。在整个系统的研发过程中,有效的提高了效率,同时最小化了设计错误。3)本系统充分利用了Visual Studio 2005的集成开发环境在界面和数据库开发上的优势进行了系统实现,使用了.Net Framework 2.0的框架和VB.Net的
4、开发语言,使得开发效率非常高,并且框架比较成熟和稳定。4)在系统测试方案设计上,本文在对传统V型和X型测试设计方案的分析基础上,采用了一种改进的测试方案对系统各个模块进行了测试。整个测试方案以黑盒和白盒单元测试相结合的方式实现,使测试更有效,更灵活。【英文摘要】At present, the network controlling and management systems have been widely applied in the whole nation for security purposes. Currently, a series of available monitorin
5、g systems have been developed by a number of commercial and organizational agencies, for solving the problem of“one machine, dual use”. Here, we developed a simple preliminary LAN monitoring system, suitable for being applied in city-level governments to reduce costs.The first chapter is dealing wit
6、h the current security situatuion of internal network of the security departments. We also give a brief introduction, describe the research background, and propose the major contents of the present study. In the second chapter, we introduce the knowledge of database and programming environmet in det
7、ail. In the third chapter, we analyze the customer requirements for security monitoring, and design the principal modules for the whole system. In the fourth chapter, we mainly present the implementation of the modules of the systems. Finally, in the last chapter, the test design and cases for the s
8、ystem are present.Our study achieved the following modules:1) Detecting and identifying the connection way for the computers being monitored, including MODEM, ASDL, pairs of network cards, and offline behaviors.2) Recording the information all kinds of illegal access to internet for the computer, in
9、cluding online time, duration time, computers IP and MAC addresses and so on.3) Recording the detailed information on the illegal computer, including name, department, network connection ways (proxy or dial-up).4) Easy query of data sets for the purpose of security searching and checking.5) Saving a
10、nd uploading the suspected alert data to the high-level security monitoring center; developing the platform of information sharing and publishing; realizing the submission of alert data using email system.Features of present network monitoring security system:1) The monitoring platform is built on t
11、he basis of server/browser (B/S) framework. On the server side, SQL Server 2000 and ACCESS database software are used. 2) The system design follows the object-oriented strategy, developed under the three-tier framework, therefore the class structure for each module can be clearly present. In the des
12、ign of database, we graph the relationships among the data, which can be vividly understood. In the whole development process, we can effectively accelerate the programming and reduce the design mistakes.3) Our system extensively used the developing environment of Visual Studio 2005, which can easil

By using .Net Framework 2.0 and VB.Net, the developing effectiveness is very high, and the system is stable.4) On the design of system testing, we not only used the traditional V- and X-type testing design, but also introduced an improved testing method. The entire testin
