【摘要】：随着信息技术的迅速发展,作为国民经济的基础设施行业的电力企业越来越依赖于信息技术和服务。随着电力信息化建没和应用高潮的到来,信息安全问题已日益突出,并成为国家安全战略的重要组成部分。信息安全的内涵也在不断发展变化着。尤其是进入二十一世纪以来,信息安全把重点放在了保护信息上,目的是确保信息在存储、处理、传输过程中不被破坏,以及对合法用户的服务和限制非授权用户的服务,所以设置必要的防御攻击措施,即强调信息的保密性、完整性、可用性、可控性,对于加固供电公司信息安全十分必要。本文从基层电力企业信息网络安全着眼,从现今先进的主动防御技术体系建构思想着手,从延安供电公司网络应用现状和管理设计方法着力,对原有公司办公网络安全现状和存在的问题进行分析,结合当前信息安全模型的最新动向,先设计出安全管理体系,并利用层次化模型设计方法,来完成网络加固的设计方案。最后对整个加固方案的性能和安全稳定性能进行科学评估。针对延安供电公司计算机网络安全的现状和需求,本论文提出的终端安全管控方法和技术,逐一实现了网络安全加固目标,而且结合工作实际比较分析设计了合理方案。为后期延安供电公司网络系统安全可靠提供了强有力的保障。
[Abstract]:With the rapid development of information technology, the electric power enterprises, as the infrastructure industry of the national economy, rely more and more on information technology and services. With the arrival of the high tide of information construction and application, the problem of information security has become increasingly prominent. And has become an important part of the national security strategy. The connotation of information security is also constantly developing and changing. Especially since entering the 21 century, information security has focused on the protection of information in order to ensure that information is stored and processed. Not to be compromised during transmission, as well as services to legitimate users and to limit services to unauthorized users, so the necessary defense measures are put in place to emphasize the confidentiality, integrity, availability, controllability of the information, It is very necessary to strengthen the information security of power supply companies. This paper focuses on the information network security of grass-roots power enterprises, starting with the idea of constructing advanced active defense technology system. Based on the network application status and management design method of Yan'an Power supply Company, this paper analyzes the current situation and problems of office network security of the original company, combines the latest trend of the current information security model, and designs the security management system first. The hierarchical model design method is used to complete the design scheme of network reinforcement. Finally, the performance and safety stability of the whole reinforcement scheme are scientifically evaluated. The present situation and requirements of the computer network security of Yan'an Power supply Company are discussed. The method and technology of terminal security management and control proposed in this paper have realized the goal of network security reinforcement one by one. In addition, the reasonable scheme is designed based on the actual work, which provides a strong guarantee for the security and reliability of the network system of Yanan Power supply Company in the later period.
