网络安全技术在城市级供电系统数据网中的应用

County-suburb power grid data network system based on network security technology

叙述信息系统安全的概念,讨论信息系统安全体系框架的各个组成部分及其之间的关系。以某城市级供电局网络安全的现状为对象,对网络结构、安全策略部署上的薄弱环节进行分析。根据信息安全体系结构,从网络基础平台、业务系统接入、安全防护等几方面总结未来的业务及安全需求,提出相关解决措施。根据网络安全设计原则和不同安全技术的特点,设计供电局网络改造整体方案。通过以上方案,较为全面地解决了电力企业数据网络由于历史原因造成的安全防范措施的缺失问题,能够有效发现安全隐患,并及时提供解决手段、提前预防和即时升级的能力,是较为高效的电力系统数据网络安全系统。

The paper analyzes the concept of information safety and discusses the relationship among member parts of information security system frame.Taking the security situation of County-city Power Grid＇s data net system as an example,the weaknesses of the net structure and security strategy dispose are analyzed.According to the system structure,the future task and safety requirements on the net basic platform,operation system connector and security protection are concluded;relative solutions are proposed.Based on the principles of net safety design and the characteristics of different safety technologies,a new project is put forward.Through this new system,the problem of lacking security protection measurements,which has been existed in power industries for a long period,has been solved.It can provide the ability of timely fault finding,corresponding solving methods,the capabilities of precaution and instant upgrade,which is an efficient and optimized power grid data network system.
