    这是一个创建于 2066 天前的主题,其中的信息可能已经有所发展或是发生改变。
    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。

    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。
