基于B/S结构的电力设备在线监测四层安全信息系统

随着计算机技术、网络技术和通信技术的飞速发展,促进了我国电力行业朝着电气化程度越来越高的方向发展.当前,各种在线监测信息系统都是采用传统的三层基于B/S结构.它主要解决了传统基于C/S(Client/Server)结构管理系统维护困难、工作量大、使用不方便、可扩展性差的等缺点,其信息流是在浏览器(←→)web服务器(←→)DB服务器之间进行,没有统一的安全系统来保证数据流的安全.针对传统基于B/S三层体系结构的在线监测信息系统在安全性上存在的问题和不足,提出了一种新的基于B/S结构的四层安全体系结构,并对各层功能进行了定义,描述了四层通用安全信息系统的工作流程,该结构可以较好地增强信息系统的安全性.

Electrical Equipment On-line Monitoring Four-layer Secure Information System Based on B/S

With the computer technology, the network technology and the communication technology,which promotes our country electric power profession to develop towards to the electrification degree more and more high direction. Nowadays various on-line monitoring information system all use traditional threer-layer b/s mode, and the traditional three-layer structure solved the problems of difficult maintenance, high capacity, inconvenient application and hard expansion of the client/server mode management system, however, since the information stream of the traditional threelayer structure was realized among the browser, the web server and database server, no unitied security system was established to guarantee the safety of data stream. This paper proposes a new four-layer security architecture based on B/S mode, in view of the insufficient on security problems in traditional three-layer architecture of on-line monitoring information system, and defines the function of each layer and the workflow of four-layer security information system, so this architecture can better enhance the safety of information system.
