针对目前传统网防御TCP同步泛滥攻击的服务器主机、路由器过滤、防火墙方法的局限性，利用主动网的动态特性，提出一种基于主动网的同步泛滥防御机制，并通过仿真实验将它与传统网环境下的防火墙防御进行了性能比较和分析，结果表明主动网技术为同步泛滥攻击提供了良好的防御性能。关 键 词 同步泛滥攻击; 防御; 防火墙; 主动网Abstract This paper outlines the limitation of some currently schemes of defending SYN-Flood in traditional networks, and presents an active network based SYN-Flood defense mechanism, which takes advantage of the active network’s dynamic environment. In additon, we analyze the performance of our scheme via simulation experiments and compare it with the firewall based mechanism . The experiments show that active network based mechanism provides better capability for SYN-Flood defending.Key words SYN-Flood attack; defense; firewall; active network
