基于网络的安全要素提出了一个综合防卫体系模型．该模型涵盖技术与管理两个方面，由一组文档、安全机构和安全操作流程构成 ．其中安全操作流程又分产品采购，硬件层、软件层、数据信息层和使用人员层的构筑等8 个阶段 ．该综合防卫体系模型有助于规范化的安全体系的建立，对内、外环境的安全性均适宜、有 效，并具有良好的自适应性． Based on the network security elements, a comprehensive defense system model is proposed. The model covers both technology and management, and consists of a set of documents, security agencies and security operations. The safe operation process is divided into product procurement, hardware layer, software layer, data information layer and the use of personnel to build the eight stages. The integrated defense system model contributes to the establishment of a standardized safety system, which is suitable and effective for both internal and external environment and has good adaptability.
