该文提出了一种集网络安全评估分析、防护、检测和响应技术为一体的多组件动态协作式网络安全系统。该系统采用多组件动态协作模型设计,主要包括防火墙、网络探测器、主机代理、扫描器、管理控制台等多种安全组件,系统中各个组件之间能动态地密切协作,共同维护网络安全。文中重点阐述了该系统的结构、多组件协作的具体内容及其实现,以及用于支持协作的基于PKI的身份认证及保密通信机制。 This paper presents a multi-component dynamic collaborative network security system integrating network security assessment and analysis, protection, detection and response technologies. The system uses multi-component dynamic collaboration model design, including firewalls, network probes, host agents, scanners, management console and other security components, the various components of the system can dynamically close collaboration and work together to maintain network security. The article focuses on the structure of the system, the specific content of multi-component collaboration and its implementation, as well as PKI-based authentication and secure communication mechanism for supporting collaboration.
