最近接到客户反馈,网站已经在多个方面上做好了源站IP保密工作,并且在接入高防cdn之后源站服务器仍然遭受到多次ddos攻击,通过多方面排查基本确定泄露网站源站服务器IP的原因是因为ssl证书。

市面上很多工具爬虫24小时不停的抓取扫描IP,这类的工具网站通过无差别HTTP/HTTPS请求所有的IP,并将抓取到的IP地址所对应的网站记录到网站,以至于有些攻击者可以通过这类的网站可以直接查询到网站源站IP,因此我们在搭建网站的时候一定要做好屏蔽安全工作。

排查是否属于上述问题:通过https://你的源站IP,如果可以访问并且浏览器左上角锁的标志中显示了你的域名ssl证书那么就存在泄露的风险。

ssl证书导致的泄露网站源站服务器IP解决方案

解决方案

宝塔面板用户可添加一个随意的网站1.1.1.1(域名或者IP随意),然后删除宝塔创建网站默认生成的全部文件,然后为这个随意添加的网站配置一个无效的证书(本文下方会为大家提供一个无效的证书使用),配置好证书之后在宝塔面板后台:【网站】-【默认站点】中心选择刚才添加的这个随意的网站作为默认站点。
