一、源站访问控制描述
源站访问控制是在源服务器上设置访问控制，只允许云防御IP访问，云防御和源站联动提高防护安全性的方法。
接入知道创宇云防御平台后，经过云防御的攻击知道创宇均会按防御级别拦截，但因源站 IP 在接入前已经暴露过，存在攻击者已经获取到源站 IP 可直接攻击源服务器的风险。因此知道创宇建议如有条件可在接入云防御后将源站服务器 IP 更换为未暴露过的IP地址，如果不具备变更源站 IP 条件，建议尽量设置访问控制，即仅允许云防御集群 IP 访问源站，最大程度保障源服务器的安全。
二、获取云防御集群IP
知道创宇云防御共有6242个节点集群，每个集群背后均有多台服务器作为支撑，根据节点性能负载情况，知道创宇云防御会不定期为您选择最优节点集群。获取云防御集群IP时可登录云防御控制台，点击购买的产品，下拉框中点击【功能管理】，选择【通用设置】，进入【查看节点IP】中获取。

三、配置指导
通常修改站点配置文件/etc/httpd/conf/httpd.conf，如果网站配置在其它目录或文件中，修改时需与网站管理员核实,以对应配置文件情况为准。
1.配置示例：
在Apache配置文件中找到对应网站的配置，并搜索文件中是否存在Order deny，Allow，若不存在可重新创建配置内容，若存在直接修改即可。
比如云防御的节点组有两组，分别是 1.1.1.0 ~ 1.1.1.255和2.2.2.0 ~ 2.2.2.255，那么配置allow from 1.1.1.0/24就代表允许整个IP地址C段访问，而deny from all代表除以上外，对其它IP地址均不允许访问。
<blockquote>
&lt;Directory  “您的网站根目录路径”&gt;
Options Indexes FollowSymLinks
AllowOverride None
Order deny,allow
Allow from 1.1.1.0/24
Allow from 2.2.2.0/24
Deny from All
&lt;/Directory&gt;
</blockquote>

注意：设置时，节点IP请以云防御官网公布的最新节点IP为准，并将上面的网站根目录路径修改为实际路径，设置完成后，重启Apache生效。
2.验证策略是否生效：仅Allow的IP地址（云防御节点）可请求成功，其他IP地址请求均返回403拒绝。
a.修改本地Host文件，指定域名解析到源站IP。
<img class="aligncenter size-full wp-image-3575" src="http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源.png" alt="" width="1043" height="263" srcset="http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源.png 1043w, http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源-300x76.png 300w, http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源-768x194.png 768w, http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源-1024x258.png 1024w, http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源-60x15.png 60w, http://help.yunaq.com/wp-content/uploads/2021/07/绑host测试限源-150x38.png 150w" sizes="(max-width: 1043px) 100vw, 1043px" />
b.访问该域名时若出现以下报错则策略生效，若可正常访问网站则策略有误，建议核实配置情况。
<img class="aligncenter size-full wp-image-3523" src="http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图.png" alt="" width="1484" height="550" srcset="http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图.png 1484w, http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图-300x111.png 300w, http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图-768x285.png 768w, http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图-1024x380.png 1024w, http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图-60x22.png 60w, http://help.yunaq.com/wp-content/uploads/2021/07/Apache限源效果图-150x56.png 150w" sizes="(max-width: 1484px) 100vw, 1484px" />

三、配置指导
编辑Tomcat配置文件conf目录下的server.xml，在HOST部分进行设置(全局生效)。添加配置样例如下，另不同 Tomcat 版本分割符号可能有差异，如以 “|”分隔未生效，可尝试“,”分隔或查看官方配置说明。
1.配置示例：
<blockquote>
&lt;Host &#8230;&#8230;
&#8230;&#8230;
&lt;Valve className=&#8217;org.apache.catalina.valves.RemoteAddrValve&#8221;
allow=&#8221;117.21.219.*|113.107.238.*|&#8230;.&#8221; deny=&#8221;&#8221;/&gt;
&#8230;&#8230;

Tomcat Web服务器访问控制设置方法

一、NS接入方式介绍
NS接入方式是指将域名解析完全托管到知道创宇云防御平台的方式，知道创宇除了提供安全加速服务外，还提供完整的DNS智能解析、DNS抗DDoS服务，接入后，需要用户将该域名的所有子域名均迁移到云防御平台进行解析，需要防御的站点使用云端模式，不需要防御的站点使用回源模式。
二、添加域名入口
登陆后进入【域名管理】-【域名列表】-【添加域名】， 也可通过<a class="external-link" href="https://defense.yunaq.com/site/list/?f=s" rel="nofollow">https://defense.yunaq.com/site/list/?f=s</a> 直接进入。
三、接入操作步骤
1、输入根域名（如：要接入的域名为：www.example.com，则根域名为：example.com），选择“NS方式接入”，点击【添加域名】。
<img class="aligncenter size-full wp-image-3323" src="http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式.png" alt="" width="1355" height="659" srcset="http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式.png 1355w, http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式-300x146.png 300w, http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式-768x374.png 768w, http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式-1024x498.png 1024w, http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式-60x29.png 60w, http://help.yunaq.com/wp-content/uploads/2021/07/NS接入方式-150x73.png 150w" sizes="(max-width: 1355px) 100vw, 1355px" />

在腾讯云修改DNS解析指向云防御别名地址

当域名接入成功后，云防御会通过反向代理的方式对网站进行引流防护，同时隐藏源站服务器真实IP地址。验证时仅需核对解析出的IP是否为源站IP地址，如不是源站真实IP地址，则已接入云防御。云节点IP判断方式可参考：<a href="http://help.yunaq.com/faq/2201/index.html">云防御IP获取及验证</a>。
验证方式可参考以下几种方式：
1、ping 域名，解析出的IP地址非真实源站IP地址,且解析出的IP地址返回400界面。

2、通过nslookup或者dig方式来验证。
<img class="aligncenter wp-image-2937" src="http://help.yunaq.com/wp-content/uploads/2021/03/QQ图片20210719104039-e1626662485947.png" alt="" width="1000" height="665" />
3、使用第三方工具测试解析的IP是否为云防御节点IP。
4、特殊场景，若在云防御前部署了其他反向代理方式部署的服务（如第三方CDN）。可以浏览器F12查看网络加载过程中是否携带云节点代理特征，具体参考下图。
<img class="aligncenter wp-image-2789" src="http://help.yunaq.com/wp-content/uploads/2021/03/5.png" alt="" width="1000" height="418" srcset="http://help.yunaq.com/wp-content/uploads/2021/03/5.png 885w, http://help.yunaq.com/wp-content/uploads/2021/03/5-300x125.png 300w, http://help.yunaq.com/wp-content/uploads/2021/03/5-768x321.png 768w, http://help.yunaq.com/wp-content/uploads/2021/03/5-60x25.png 60w, http://help.yunaq.com/wp-content/uploads/2021/03/5-150x63.png 150w" sizes="(max-width: 1000px) 100vw, 1000px" />

一、什么是中文域名
中文域名，泛指含有中文字元的域名，同英文域名一样，是互联网上的门牌号码，它在技术上符合2003年3月份IETF发布的多语种域名国际标准(RFC3454、RFC3490、RFC3491、RFC3492)。中文域名属于互联网上的基础服务，注册后可以对外提供WWW、Email、FTP等应用服务。
目前已经有越来越多用汉字表现的中文域名，例如：“.中国”、“.公司”、“.网络”、“.手机”、“.世界”、“.公司”等。
二、如何添加中文域名
步骤一：在<a href="https://defense.yunaq.com/tools/dnstranscoding/">https://defense.yunaq.com/tools/dnstranscoding/</a>进行中英文转码。

目前知道创宇云防御仅支持主机名为中文的情况，暂不支持后缀为中文的域名。
例如：支持：测试.cn，不支持：测试.网络。
