几天以来，我的 Apache Web 服务器一直受到攻击。我收到来自多个 IP 的多个对不存在页面的请求。除了关闭 Apache 服务器外，我还能做些什么来阻止它？
目前我已经关闭了端口 80 以阻止日志填满。这是我的 error.log 的一部分：

它们都是不同的 IP，所以我的 iptables 中的暴力保护没有帮助。
有什么建议么？
答案1
我在谷歌上搜索，发现了这一点：

似乎 apache2 有一个特殊的模块可以防止引荐来源垃圾邮件。
或者
使用 iptables 的更手动的方法：

答案2
如果您希望服务器公开，则没有办法完全阻止它，但您可以使用 mod_evasive 智能地阻止发出过多请求的主机和/或使用 mod 安全性来匹配模式并根据模式阻止主机。
这些可能最终都会消失
