我上周主持了我的Rails应用程序.今天我正在浏览我们的日志文件并注意到很多这样的请求.
I,[2016-03-14T00:42:18.501703 #21223] INFO -- : Started GET "/testproxy.php" for 185.49.14.190 at 2016-03-14 00:42:18 -0400

有人试图从不同的IP地址转到testproxy.php.有些ip来自波兰,有些来自香港.我被某人袭击了吗？我有什么保护自己的选择.
以下是日志文件中的其他输出：

还有很多其他的东西.请告诉我如何保护自己免受这些攻击.
当您运行公共服务器时,这很常见.这是我家庭服务器的auth.log的摘录：

正如您所看到的那样,人们不断尝试通过猜测用户名来侵入我的服务器.由于服务器只接受publickey登录,而不是密码,我相信自己对这些特殊攻击相当安全.
这同样适用于您的PHP文件.他们正试图找到一个他们可以运行一些罐头漏洞的php端点.您可以使用fail2ban等工具来帮助限制速率.但实际上这些攻击总是存在于公共服务器上.唯一的方法是确保您的软件能够抵御攻击.
一些常识常识提示：
>不要运行超出您需要的服务,因为任何一项服务都可能会打开您的服务器进行攻击.使用nmap检查已打开的端口.
>检查您的apache / nginx配置是否允许执行超过必要的更多(PHP)文件.
>不断更新您的软件.这些攻击中的大多数是自动化的,因此依赖于常见包中的已发布漏洞.
