火电企业的燃料信息是电厂经营中保密程度高的绝密数据,其信息安全等级保护建设是智慧电厂信息化建设中的重要组成部分,可为火电企业信息安全建设提供基础支撑。针对火电企业等级保护建设的要求,从政策支撑、级别确定的角度出发,以总装机1000MW为分界点,分别按照第2级、第3级进行安全保护等级的分类。依照“安全分区、网络专用、横向隔离、纵向认证”的总体防护原则,分析火电企业燃料信息安全所需的物理环境,对机房安全、供电安全,网络构架、区域边界与运维管理、系统综合防护等系统建设管理方面进行深度探讨,并提出软硬件建设要求及梳理等保测评的4个步骤,落实等级保护测评的周期要求,针对网络安全等级保护测评则确定2级定级的系统一般每2年开展1次,而3级定级的系统要求每年至少开展1次等保测评。通过等级保护的引入,将信息安全等级保护形成持续性的长期迭代工作,可对火电企业的信息安全建设提供指导作用。

The fuel information is the top secret data with a high degree of confidentiality in the operation of thermalpower enterprises, the information security classified protection construction is an important part of the informatiza⁃tion construction of smart power plants, which can provide basic support for the information security constructionof thermal power enterprises. In view of the requirements for the hierarchy protection construction of thermal power en⁃terprises, from the perspective of policy support and level determination, the capacity of 1 000 MW is used as the di⁃viding point, and the safety protection levels are classified according to Level 2 and Level 3 respectively. In accord⁃ance with the total protection principles of “ security partition, network dedicated, horizontal isolation and verticalauthentication”, the physical environment required for information security is analyzed, and the system construc⁃tion management aspects such as computer room security, power supply security, network architecture, regionalboundaries and operation and maintenance management, and comprehensive system protection are conductedin⁃depth discussions, and the requirements of software and hardware construction are proposed. Sort out the foursteps of the level protection assessment and implement the cycle requirements of the level protection assessment.For the network security level protection assessment, it is determined that the level 2 system is generally carried outonce every two years, while the level 3 system requires at least once every year. Through the introduction of levelprotection, information security level protection can be formed into a sustainable long⁃term iterative work, which canprovide guidance for the information security construction of thermal power enterprises.
