如何使用云形成模板在 S3 存储桶上设置 SSE-S3 或 SSE-KMS 加密？

Question

我正在尝试使用 CloudFormation 模板在 AWS 中启动 S3 存储桶。该项目的要求之一是对存储桶进行就地加密。我一直在尝试找到一种通过 CloudFormation 模板进行设置的方法（我已经阅读了所有我可以获得的关于 SSE-S3、KMS、CFT 和 S3s 的文档……）。但所有迹象似乎都表明它只能通过控制台使用。

我担心我只是遗漏了一些明显的东西，我想知道是否有人知道我如何使用 CloudFormation 模板（或至少是自动化的东西）将 S3 存储桶的默认加密设置为 SSE-S3 或 SSE -KMS?

Answer 1

AWS 添加了此功能on January 24th, 2018：

Use the BucketEncryption property to specify default encryption for a bucket using server-side encryption with Amazon S3-managed keys SSE-S3 or AWS KMS-managed Keys (SSE-KMS) bucket.

JSON

{
  "Resources": {
    "MyBucket": {
      "Type" : "AWS::S3::Bucket",
      "Properties" : {
        "BucketEncryption": {
          "ServerSideEncryptionConfiguration": [
            {
              "ServerSideEncryptionByDefault": {
                "SSEAlgorithm": "AES256"
              }
            }
          ]
        }
      }
    }
  }
}

YAML

您也可以使用 ForceEncryption 选项：

AWSTemplateFormatVersion: '2010-09-09'
Description: Amazon S3 Bucket with 

Resources:
  CodeFlexS3Bucket:
    Type: AWS::S3::Bucket
    Properties:
      AccessControl: Private
      BucketName: !Join ["-", ["codeflex-example", Ref: "AWS::Region"]]

  ForceEncryption:
    Type: AWS::S3::BucketPolicy
    Properties:
      Bucket: !Ref CodeFlexS3Bucket
      PolicyDocument:
        Version: "2008-10-17"
        Statement:
          - Sid: DenyUnEncryptedObjectUploads
            Effect: Deny
            Principal: "*"
            Action:
              - s3:PutObject
            Resource:
              - !Join ["", ["arn:aws:s3:::", !Ref CodeFlexS3Bucket, "/*"]]
            Condition:
              StringNotEquals:
                "s3:x-amz-server-side-encryption":
                  - "aws:kms"
    DependsOn: CodeFlexS3Bucket

Answer 3

如果您有特定的 KMS 密钥，请使用以下内容

  ConfigBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: "mytestbucketwithkmsencryptionkey"
      AccessControl: PublicRead
      BucketEncryption: 
        ServerSideEncryptionConfiguration: 
        - ServerSideEncryptionByDefault:
            SSEAlgorithm: aws:kms
            KMSMasterKeyID: "YOUR KMS KEY ARN"
