【中文标题】当我检查 nginx access.log 时，未知的 HEAD 请求会定期进入【英文标题】：When I check nginx access.log, unknown HEAD requests come in periodically 【发布时间】：2017-12-18 23:22:36 【问题描述】：

首先，我使用服务器环境：

    服务器：nginx + uwsgi + django 应用、docker + AWS ECS 部署 芹菜：rabbitmq ec2 缓存：redis ec2 日志记录：AWS CloudWatch 日志 + watchtower 第三方应用程序

当我访问 ECS EC2 并检查 nginx access.log 时，会定期进入以下请求。 为什么会向我提出这个要求？这是您第一次打开服务器时不断出现的内容。

另外，我的ecs服务器的安全组80/443端口开放到任何地方。

nginx/access.log

【问题讨论】：

10.0.1.234 是谁？ @Fabien hmm..我向我办公室的API发送请求，IP也记录为10.0.1.234。 @Fabien 可能是 ELB 的 IP 这可能是他们ELB的IP地址。在这种情况下，所有这些看起来都像是寻找弱目标的漏洞扫描器的枚举。只是随机扫​​描，就像有数千个一样。 @Fabien 更改日志记录 ip 地址，该 ip 灵活 【参考方案1】：

这是来自漏洞扫描工具ZmEu 的一个非常典型的请求模式。长话短说，黑客正在运行一个自动化工具，试图在您的系统上找到一个易受攻击的 PHPMyAdmin 安装，并利用它来获得对您系统的 root 访问权限。即使您的系统上没有 PHPMyAdmin 也没关系，他们仍然会发出请求，只是为了测试并查看您是否这样做，因为这样做很便宜，如果他们确实找到了可以利用的东西，他们可以进入您的服务器窃取数据或将其用于邪恶目的。

不幸的是，这只是在互联网上拥有一台服务器的成本，人们不断地对他们可以访问的任何服务器运行自动扫描工具，试图找到入侵并接管它的方法。

【讨论】：

我们可以使用 fail2ban 缓解这些“攻击”吗？ 是的，但是对于这样的事情，通常不值得引入额外的开销。将 404 服务返回给攻击者几乎不会花费您任何费用。根据禁止 IP 的数据库检查和验证所有入站 IP 地址的成本要高得多。
