摘 要: 从系统论、控制论的一般观点出发,研究防火墙、入侵检测系统、入侵防御系统、统一威胁管理系统等网络安全设备的发展与应用,揭示反馈控制在包过滤防火墙向状态检测防火墙演进、入侵检测系统向入侵防御系统演进过程中的重要作用。把反馈控制的原理应用到网络安全态势感知系统中,提出一种多级反馈、协同工作的网络安全态势感知系统结构,该系统能更有效地收集网络信息来进行安全态势评估。 From the viewpoint of system theory and cybernetics, the development and implementation of network security equipments such as firewall and intrusion detection system is analyzed. It is revealed that the feedback plays an important role in the functions of these equipments. And then a network situation awareness system of multi-level feedback and cooperative work is proposed. This system is proved quite effective in collecting network information and assessing security situation.
