刚才无意看到阿里云上的服务器的有很多像下面的log

... client: 91.208.16.231, server: xxx.com, request: "GET /admin.php HTTP/1.1", upstream: "fastcgi:// 127.0.0...
... client: 113.108.82.22, server: xxx.com, request: "GET /admin.php HTTP/1.0", upstream: "fastcgi:// 127.0.0...
... client: 113.108.82.22, server: xxx.com, request: "GET /misc.php?mod=faq HTTP/1.0", upstream: ...
... client: 24.114.29.162, server: xx.com, request: "GET /admin.php HTTP/1.0", upstream: "fastcgi:// 127.0.0...

像是被人在扫描。针对这种情况，一般需要做哪些防护措施，有什么工具推荐呢？

@austinchou0126 这个你敢在vps上用？这个对于有点流量的站一般级别日志输出就会瞬间99 CPU，过不了多久就abuse了

和楼主一样，感觉是脚本小子开了个工具，就开始扫描了，自动的，扫完没发现什么漏洞，估计它就离开了？

从这里看构造的url，倒是可以学习一点防攻击的经验，免得自己在这些地方露馅了。

@lightforce 有啥建议么

用 .htaccess 给网站管理员页面设置白名单。只有你自己的 IP 可以访问管理员页面，其他 IP 就 403 拒绝掉。
