amazon-web-services - 为什么我的 AWS S3 策略不会仅限制某些 IP 地址的访问？

问题描述

我正在努力在 AWS 中创建 S3 策略。S3 存储一个 mp4 视频。我已经根据用户名或密码启动了访问，但是当我尝试限制 IP 访问时（只想让这个视频从某个 IP 地址访问，只有我的家庭和办公室 IP 地址）。

我使用 myipaddress.com 并在 cmd 中查找“IPconfig”功能以提供子网掩码代码（/19，但有些使用 /32、/24 等）但是当我使用另一个 IP 地址时，它允许使用视频. 换句话说，任何观看此视频的人都无法限制访问。以下是政策代码。

解决方案

任何人都可以查看此视频，我无法限制访问。

这不是它的工作方式。您的策略是 IAM 策略，而不是存储桶策略。这意味着只有您启用了明确允许的 IAM 用户和角色才能访问视频。您的政策不允许匿名访问。

此外，您的拒绝将仅适用于来自地址的请求。96.70.32.38/19如果您要使用不同的 IP，则该策略不适用。要将拒绝应用于所有其他 IP 地址，除了您自己的，您需要NotIpAddress，而不是IpAddress在AWS 文档Condition中解释的那样。此外，您的第一条语句将仅适用于bucket，而不适用于它的对象。对于您需要的对象和存储桶：

 "Resource": [
      "arn:aws:s3:::internshipbucket12",
      "arn:aws:s3:::internshipbucket12/*",
  ]

此外，默认情况下存储桶和对象 是私有的。因此，您无需使用带有明确拒绝的 IAM 策略。默认情况下，没有人可以访问存储桶及其内容，除非您作为管理员在策略中允许这样做。
