如何屏蔽垃圾邮件请求

codeArt asked 7 年 ago

主机部署在腾讯云上，使用lamp 部署oneinstack之后查看 Apache_log 记录时发现大量异常连接请求
类似于

这应该就是“网络嗅探”了，虽然屏蔽了ip，但是嗅探仍然继续，以域名的方式。

经过监测发现大量的异常代理及异常登陆行为。
1、启用Fail2ban脚本可以进行基础防御；总觉得腾讯云的防御好像没起什么作用[默认规则以及apache-proxy]
2、如果使用经典网络，则开始限制端口，将没用的端口屏蔽掉[公网保留基础端口80，22]之类的
3、不建议在控制台屏蔽IP，就算屏蔽IP，他仍然会继续攻击
这样就可以进行基础防御
