摘　　要：为减少分布式反射拒绝服务攻击,保障网络安全,基于NTP反射放大攻击原理,建立实验模型,结合wireshark软件抓包分析其攻击效果,研究了NTP协议原生安全漏洞被利用的原理,在此基础上提出防范方法。应针对新型反射放大DDoS攻击,开展网络协议研究,各方通力合作,形成高效防御技术和方案,减少利用NTP服务漏洞开展的攻击行为。In order to reduce the distributed reflection denial of service attack,and guarantee the network security,the study establishes experiment model based on the principle of NTP reflection amplification attack,captures and analyzes its attack effect through combining with wireshark software,researches the principle of the utilization of original security loophole of NTP protocol,and proposes precautionary methods.It is suggested to develop network protocol research according to new reflection amplification DDoS attack,join forces,form high efficient defense technology and scheme,and reduce aggressive behavior through the utilization of NTP service loophole.
