【摘要】：随着计算机和网络技术的不断进步,各高校都已先后建成了自己的内部校园网和计算机机房,通过与外网的连接,实现了高校教学的自动化、网络化,同时也为学生的上机学习提供了诸多方便。但随着互联网信息的不断膨胀,各种不健康的信息,诸如色情、暴力、赌博等,不断充斥于学校机房网络中,这些信息已逐渐影响了在校学生的心理健康。此外,由于部分学生自制能力有限,过度沉溺于网络游戏中,或是其它不良上网习惯,都导致了身心健康出现下滑。以上问题的存在,迫切需要通过信息技术的手段加强对高校机房网络的监管,不断规范校园网络的运行。论文在深入分析浙江警察学院计算机机房日常网络监控管理工作的基础上,综合比较学校已有的软硬件设施,设计了一个结合管理、监视和控制于一体的网络监控系统。该系统基于C/S开发模式,采用MVC开发框架,运用ADO.NET数据库访问技术以及C#程序设计语言进行开发。经过详细的需求分析、设计和实现,目标系统的研究内容包括系统管理、日志管理、规则管理、内容过滤、流量管理等功能模块,通过系统管理功能,可以对机房中的服务器和用户权限进行设置;通过日志管理功能,可以对系统的日志和计算机中的文件传输记录进行查询;通过规则管理功能,可以对机房中的单机规则和全局规则进行设置;通过内容过滤功能,可以对计算机中的邮件收发和聊天内容进行过滤;通过流量管理功能,可以对机房网络的总带宽流量进行管理,同时利用流量统计排行功能,实现对机房上网流量情况的监控。目标系统的应用,有效改善了浙江警察学院当前的机房管理工作现状,在不影响学生正常上机操作的情况下,能够对每一位学生的上网行为进行授权认证,并对学生的所有上机行为进行监控,使得学生能够严格遵照学校机房的上机要求,杜绝学生利用上机时间进行其它课程之外的操作,确保学校的网络资源得到充分的利用。
[Abstract]:With the continuous progress of computer and network technology, each university has built its own internal campus network and computer room successively. Through the connection with the external network, it has realized the automation and networking of teaching in colleges and universities. At the same time, it also provides a lot of convenience for students to study on the computer. But with the expansion of Internet information, various unhealthy information, such as pornography, violence, gambling and so on, are constantly flooded in the school computer room network, these information has gradually affected the mental health of students in school. In addition, some students have limited self-control, excessive addiction to online games, or other bad Internet habits, resulting in a decline in physical and mental health. With the existence of the above problems, it is urgent to strengthen the supervision of the computer room network in colleges and universities through the means of information technology, and to standardize the operation of the campus network. On the basis of deeply analyzing the daily network monitoring and management work in computer room of Zhejiang Police College, this paper synthetically compares the existing hardware and software facilities in the school, and designs a network monitoring system which combines management, monitoring and control. The system is based on C / S development mode, adopts MVC development framework, uses ADO.NET database access technology and C # programming language to develop. After detailed requirements analysis, design and implementation, the research content of the target system includes system management, log management, rule management, content filtering, traffic management and other functional modules, through the system management function, You can set the server and user permissions in the computer room, query the system log and the file transfer records in the computer through the log management function, through the rule management function, It can set the single machine rules and global rules in the computer room, filter the mail, send, receive and chat content in the computer through the content filtering function, through the flow management function, The total bandwidth flow of the computer room network can be managed, and the traffic statistics and ranking function can be used to realize the monitoring of the network flow in the computer room. The application of the target system has effectively improved the current situation of computer room management in Zhejiang Police College. Without affecting the normal operation of students on the computer, it can authorize and authenticate every student's behavior on the Internet. And all the students on the computer behavior monitoring, so that students can strictly comply with the requirements of the school computer room, prevent students from using computer time to operate outside other courses, to ensure that the school's network resources are fully utilized.
