【摘要】：随着全球信息化的高速发展，未来战争已经成为以计算机网络为核心的信息战，谁掌握制信息权，谁就拥有了主动权，从而控制整个战场。而网络的开放性又使得计算机网络系统成为敌方攻击的重点。因此，军队网络安全变得日益突出和重要。当前，计算机应用在军队信息化建设中得到普及，我军网络安全问题也逐渐突显，国家自主产品缺失、网络核心技术落后、官兵安全意识淡薄、军队安全管理制度不完善、网络安全防护能力弱，军队网络泄密和网络被攻击事件屡有发生。如果这些问题不能引起足够重视，并很好的得到解决，将会严重影响我军在未来信息化战争中的战斗力，成为我军未来战争中的死穴，直接影响战争的结果。因此，如何加强军队网络安全防护能力，提高网络攻防能力是当前军队迫切需要解决的课题。本文依托我所在单位计算机网络平台，分析了当前军队网络安全及网络管理现状，，找出军队存在的网络安全问题，提出解决建议和意见。针对我单位存在的网络安全隐患，以网络管理、SNMP协议和网络安全防护技术等理论为基础，提出加强我单位计算机网络安全防护系统方案。本文重点放在研究和设计基于SNMP协议的网络管理系统，提高我单位的网络运行能力。通过采集网络在线设备的各种信息，并对采集的数据进行统计、分析，然后生成报表或发出警示，以实现对我单位计算机网络的安全管理与维护。其中对系统开发用到的数据采集、拓扑发现、故障告警和设备管理等模块做了深入研究，详细论述了设计方案和关键模块的实现过程。
[Abstract]:With the rapid development of global information technology, the future war has become the computer network as the core of the information war, who has the right to control information, who has the initiative. The openness of the network makes the computer network system become the focus of the enemy attack. Therefore, the military network security has become increasingly prominent and important. At present, the application of computer has been popularized in the construction of military information, and the problems of network security of our army have gradually become prominent. The lack of independent products of the state, the backwardness of network core technology, and the weak sense of security of officers and soldiers. The military security management system is not perfect, the network security protection ability is weak, the military network leaks and the network is attacked frequently. If these problems can not cause enough attention, and are well solved. It will seriously affect the combat effectiveness of our army in the future information war, become the dead hole in the future war of our army, and directly affect the result of the war. Therefore, how to strengthen the military network security protection capability. It is an urgent task for the army to improve the ability of network attack and defense. Based on the computer network platform of my unit, this paper analyzes the current situation of military network security and network management, and finds out the problems of military network security. In view of the hidden danger of network security in our unit, it is based on the theory of SNMP protocol and network security protection technology. This paper focuses on the research and design of network management system based on SNMP protocol. Improve the network operation ability of our unit. Through collecting all kinds of information of the network on-line equipment, and to collect the data to carry on the statistics, analysis, then generate the report form or send out the warning. In order to realize the security management and maintenance of our unit computer network, the data acquisition, topology discovery, fault alarm and equipment management modules used in the system development are deeply studied. The design scheme and the implementation process of the key modules are discussed in detail.
