cc攻击
攻击者借助代理服务器生成指向受害主机的合法请求，实现DDOS和伪装就叫：CC(ChallengeCollapsar)。
CC主要是用来攻击页面的。大家都有这样的经历，就是在访问论坛时，如果这个论坛比较大，访问的人比较多，打开页面的速度会比较慢，访问的人越多，论坛的页面越多，数据库压力就越大，被访问的频率也越高，占用的系统资源也就相当可观。
一个静态页面不需要服务器多少资源，甚至可以说直接从内存中读出来发给你就可以了，但是论坛就不一样了，我看一个帖子，系统需要到数据库中判断我是否有读帖子的权限，如果有，就读出帖子里面的内容，显示出来——这里至少访问了2次数据库，如果数据库的数据容量有200MB大小，系统很可能就要在这200MB大小的数据空间搜索一遍，这需要多少的CPU资源和时间？如果我是查找一个关键字，那么时间更加可观，因为前面的搜索可以限定在一个很小的范围内，比如用户权限只查用户表，帖子内容只查帖子表，而且查到就可以马上停止查询，而搜索肯定会对所有的数据进行一次判断，消耗的时间是相当的大。
CC就是充分利用了这个特点，模拟多个用户（多少线程就是多少用户）不停的进行访问（访问那些需要大量数据操作，就是需要大量CPU时间的页面）.这一点用一个一般的性能测试软件就可以做到大量模拟用户并发。
