摘要
随着电力信息网络系统接入Internet,网络信息安全问题日趋严重,既要防止内部的攻击,也要防止病毒、黑客和非法访问等各种互联网上的攻击,信息网络的安全已成为影响电力系统安全运行的关键。必须针对各自特点采取相应的安全技术,通过综合设计解决其网络信息安全问题。本文从物理层、网络层、系统层、应用层、安全管理层五个层次详细分析了电力网络信息系统的特点和安全策略。
Along with the electric power information network system connecting into the Interuet, the network and information securities are gradually serious. The electric power information network system not only prevents various attacks from the inner network, but also prevents various attacks from the Internet, such as virus, hackers and illegal access; the securities of the electric power information network system have become the key to affect the electric power system run safely. So we must adopt and integrate the corresponding security techniques to solve its network and information securities according to its characteristics. This paper analyzes the characteristics of the electric power information network system from the physical level, the network level, the system level, the application level and the management level, and proposes the detailed security strategy.
