  • 第2题：

    什么是DistributedD.O.S（Distributed Denial Of Service）分布式拒绝服务


    正确答案: 这是一种黑客攻击的手段。这种攻击的简单原理是：攻击者首先通过一些常用的黑客手段侵入并控制一些肉鸡（客户端主机），通过在这些主机上安装并启动一个进程，使得这些主机听命于攻击者的特殊指令。当攻击者把攻击目标的IP地址作为指令下达给这些进程的时候，这些进程就开始向目标主机发送攻击。这种方式集中了几百台甚至上千台服务器的带宽能力，对单一目标实施攻击，其威力极其巨大，通常会造成其被攻击网络的瘫痪或拒绝对外服务，因此被称为分布式拒绝服务攻击。
