我应该关心在日志里看到这个吗？

Question

在我的Nginx访问日志中，以下请求(这是其中的一半)都是在几分钟内从注册到越南ISP的IP (我可以提供IP，但我不确定是否允许她)发出的。我昨天刚安装了服务器。注意libwww-perl/5.805用户代理和路径(查找公共配置文件等)。

我应该关注这个问题吗，还是有那么多的机器人在扫描IP，以至于每天都不可避免地得到这样的扫描？

Answer 1

你会得到像这样的扫描，任何IP暴露在互联网上。这是你应该看到的正常背景噪音的一部分。

可以使用各种工具对执行这种扫描的IP进行评级、限制或禁止-- mod_security、iptables、fail2ban等，但通常没有必要。

Answer 2

您的假设是正确的:花费时间(以及所有者的带宽分配)研究漏洞的受损主机的数量可能会达到数百万。从时间戳可以看出，攻击是自动的。

阅读这些攻击是有指导意义的，因为它可以让您了解正在被探测的漏洞，但一般来说，它们只是提醒您保持系统的修补和安全。
