1. Login to AWS Console: Go to the AWS Management Console (https://aws.amazon.com/) and log in using your credentials.
2. Navigate to DynamoDB: In the AWS Management Console, search for “DynamoDB” in the services search bar and select DynamoDB from the search results.
3. Select the Table: From the DynamoDB dashboard, select the table where the notebook data is stored that needs to be encrypted with AWS managed keys.
4. Enable Encryption: Click on the “Manage” tab in the table details page and then click on the “Encryption” tab.
5. Edit Encryption Settings: Click on the “Edit” button to edit the encryption settings for the DynamoDB table.
6. Select AWS Managed Key: In the Encryption settings, select “AWS managed key” as the key provider instead of “KMS Customer Master Key”.
7. Choose AWS Managed CMK: Choose an AWS managed Customer Master Key (CMK) from the list provided. You can select the default AWS managed CMK or create a new one.
8. Update Encryption Settings: After selecting the AWS managed CMK, click on the “Save” button to update the encryption settings for the DynamoDB table.
9. Monitor Encryption Status: Once the encryption settings are updated, monitor the status to ensure that the notebook data is now encrypted with the AWS managed key.

​

1. Update the DynamoDB Table Encryption: Configure the DynamoDB table to use AWS managed encryption instead of KMS Customer Master Keys. You can do this by updating the table settings to use the default AWS managed encryption.
2. Install the AWS SDK for Python (Boto3): If you haven’t already, install the Boto3 library, which is the AWS SDK for Python. You can install it using pip:

pip install boto3

3. Update the DynamoDB Table Encryption Settings: Use the following Python script to update the encryption settings of the DynamoDB table to use the default AWS managed encryption:

import boto3

# Specify the region where your DynamoDB table is located
region = 'your-region'

# Specify the name of the DynamoDB table
table_name = 'your-table-name'

# Create a DynamoDB client
dynamodb = boto3.client('dynamodb', region_name=region)

# Update the table encryption settings to use AWS managed encryption
response = dynamodb.update_table(
    TableName=table_name,
    SSESpecification={
        'Enabled': True,
        'SSEType': 'AES256'
    }
)

print("Table encryption settings updated successfully.")

4. Run the Python Script: Save the above Python script in a file (e.g., update_dynamodb_encryption.py) and run it using the Python interpreter. Make sure to replace 'your-region' and 'your-table-name' with the actual values for your DynamoDB table.

python update_dynamodb_encryption.py

5. Verify the Encryption Settings: After running the script, verify that the encryption settings for the DynamoDB table have been successfully updated to use the default AWS managed encryption. You can check this in the AWS Management Console or by using the Boto3 library to describe the table.

resource "aws_dynamodb_table" "THIS_TABLE" {
  name         = "REPLACE_WITH_TABLE_NAME"
  billing_mode = "PAY_PER_REQUEST"

  hash_key = "REPLACE_WITH_HASH_KEY_ATTRIBUTE_NAME"

  attribute {
    name = "REPLACE_WITH_HASH_KEY_ATTRIBUTE_NAME"
    type = "S" # or "N" / "B" as appropriate
  }

  # Encrypt table data with a customer-managed KMS key instead of the AWS-managed key
  server_side_encryption {
    enabled     = true
    sse_type    = "KMS"
    kms_key_arn = aws_kms_key.DDB_KMS_KEY.arn
  }
}

resource "aws_kms_key" "DDB_KMS_KEY" {
  description             = "KMS CMK for DynamoDB table REPLACE_WITH_TABLE_NAME"
  deletion_window_in_days = 30

  # Optionally scope key usage with a key policy; ensure principals that use
  # DynamoDB have permission to use this key.
  policy = data.aws_iam_policy_document.DDB_KMS_POLICY.json
}

data "aws_iam_policy_document" "DDB_KMS_POLICY" {
  statement {
    sid    = "AllowDynamoDBUseOfTheKey"
    effect = "Allow"

    principals {
      type        = "Service"
      identifiers = ["dynamodb.amazonaws.com"]
    }

    actions = [
      "kms:Encrypt",
      "kms:Decrypt",
      "kms:ReEncrypt*",
      "kms:GenerateDataKey*",
      "kms:DescribeKey"
    ]

    resources = ["*"]
  }

  # Add additional statements granting your IAM roles/users permission
  # to administer and use this CMK as needed.
}

• REPLACE_WITH_TABLE_NAME with your DynamoDB table name.
• REPLACE_WITH_HASH_KEY_ATTRIBUTE_NAME with the primary key attribute name.
• Extend the KMS key policy to include your IAM roles/users as appropriate.

• On a new table: creation of aws_kms_key.DDB_KMS_KEY and aws_dynamodb_table.THIS_TABLE with server_side_encryption enabled, sse_type = "KMS", and kms_key_arn set.
• On an existing table: a planned destroy/create of aws_dynamodb_table.THIS_TABLE with the new server_side_encryption configuration using your CMK.
