【摘要】 文章首先对传统的安全防御系统(防火墙和入侵检测系统)研究现状进行了简要的综述,然后通过对现有安全防御系统在主动响应方面的缺陷进行了分析,结合主动网的技术优势,给出了基于安全主动节点的主动安全防御系统概念原型。最后,通过基于主动网的安全防御系统对DDos攻击的防御分析,证明了原型的可行性,并指明了目前研究中存在的问题和今后的工作方向。更多还原

【Abstract】 This paper firstly studies the traditional security defense system,which includes firewall and Intrusion dection system.With the analyze of deficiencies in current systems and advantages of Active Network,the authors propose an active Intrusion Response System Prototype based on Active Network.Then through the DDos Attack defense example,the authors prove the feasibility of the prototype based on Active Network.Finally,problems and directions still under research are mentioned briefly.更多还原
