如何使用云编队模板在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 Bucket。 该项目的一个要求是对存储桶进行加密。 我一直试图通过CloudFormation模板找到一种方法来设置它（我已经阅读了所有可以获得SSE-S3，KMS，CFT和S3s的文档......）。 但所有迹象似乎都指向它只能通过控制台获得。

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如何使用CloudFormation模板（或至少是自动化的东西）将S3 Bucket的默认加密设置为SSE-S3或SSE-KMS？

Answer 1

AWS 于2018年1月24日添加了此功能：

使用BucketEncryption属性为使用服务器端加密的存储桶指定默认加密，使用Amazon S3管理的密钥SSE-S3或AWS KMS管理的密钥（SSE-KMS）存储桶。

JSON

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

YAML

Resources:
  MyBucket:
    Type: "AWS::S3::Bucket"
    Properties: 
      BucketEncryption: 
        ServerSideEncryptionConfiguration: 
        - ServerSideEncryptionByDefault:
            SSEAlgorithm: AES256

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

从这里开始： 通过CloudFormation创建带有KMS加密的S3存储桶

Answer 3

如果您有特定的KMS密钥，请使用以下命令

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