如何防护 DNS 放大攻击

对于运行网站或服务的个人或公司来说，缓解选择并不多。这是因为，尽管个人或公司的服务器可能是攻击目标，但其并非容量耗尽攻击影响最大的地方。鉴于攻击所产生的大量流量，服务器周围的基础设施感受到影响。互联网服务提供商（ISP）或其他上游基础设施提供商可能无法处理传入流量而不堪重负。因此，ISP 可能会将向受害者 IP 地址发送的所有流量传送到一个黑洞路由，以保护自己并将目标站点下线。除了象 Cloudflare DDoS 防护这样的异地保护服务外，缓解策略大多是预防性的互联网基础设施解决方案。       减少开放 DNS 解析器的总数      DNS 放大攻击的一个重要组成部分是对开放 DNS 解析器的访问权限。如果互联网上有配置不当的 DNS 解析器，那么攻击者只要找到这种 DNS 解析器就能加以利用。理想情况下，DNS 解析器应仅向源自受信任域名的设备提供服务。在基于反射的攻击中，开放 DNS 解析器将响应来自互联网任何位置的查询，因此有可能被利用。限制 DNS 解析器，使其仅响应来自受信任来源的查询，即可使服务器无法被用于任何类型的放大攻击。        源 IP 验证 —— 阻止欺骗性数据包离开网络       由于攻击者僵尸网络发送的 UDP 请求必须有一个伪造为受害者 IP 地址的源 IP 地址，对于基于 UDP 的放大攻击，降低其有效性的一个关键是互联网服务提供商（ISP）拒绝带有伪造 IP 地址的所有内部流量。如果一个从网络内部发送的数据包带有一个看起来像来自网络外部的源地址，那么它就有可能是伪造数据包并可被丢弃。Cloudflare 强烈建议所有提供商实施入口过滤，并不时联系无意中参与了 DDoS 攻击的 ISP，帮助其了解自己的漏洞。
