分布式拒绝服务攻击(DDoS)原理及防范

Principle and Prevention of Distributed Denial of Service (DDoS)

分布式拒绝服务攻击(DDoS)是目前黑客经常采用而难以防范的攻击手段。本研究从概念开始详细介绍了这种攻击方式,着重描述了黑客是如何组织并发起的DDoS攻击,结合其中的Syn Flood实例,可以对DDoS攻击有更形象的了解。作者结合自己的经验与国内网络安全的现况探讨了一些防御DDoS的实际手段。

Distributed denial of service（DDoS） currently used by the hackers is difficult to guard against.In this article its concept was in detail introduced,with focus on describing how the hacker organized and launched DDoS attacks,in combined with the Syn Flood example,and a better understanding of DDoS attacks was achieved.Finally,combined with the author’s own experience and the domestic network security status,some practical ways to defense DDoS were discussed.
