以信息系统安全等级保护基本要求为基础,以信息系统等级保护安全设计技术要求为指导,按照分区、分域、分级的防护方针,结合安全管理中心、区域边界安全防护、本地计算环境防护、通信网络安全防护和相关技术手段与功能要求,设计出信息系统安全防护框架体系。并提出了信息系统安全等级保护的整体安全防护策略,以及不同信息系统间共用资源的安全防护策略。供各行各业在开展信息系统安全等级保护规划设计与实施建设时参考。 Based on the basic requirements for the protection of information system security level, guided by the technical requirements of information system level protection security design, according to the protection policy of partitioning, domain division and grading, combined with the security management center, the regional border security protection, the local computing environment protection and communication Network security and related technical means and function requirements, design information system security framework. And put forward the overall security protection strategy of the information system security level protection and the security strategy of sharing the resources between different information systems. For all walks of life in carrying out information system security level protection planning, design and implementation of construction reference.
