Choose security preferences

Setting security adds the permissions and encryption settings for your Amazon Snow Family devices job to help protect your data while in transit.

To set security for your job
  1. In the Encryption section, choose the KMS key that you want to use.

    • If you want to use the default Amazon Key Management Service (Amazon KMS) key, choose Amazon/importexport (default). This is the default key that protects your import and export jobs when no other key is defined.

    • If you want to provide your own Amazon KMS key, choose Enter a key ARN, provide the Amazon Resource Name (ARN) in the key ARN box, and choose Use this KMS key. The key ARN will be added to the list.

  2. In the Choose service access type section, do one of the following:

    • Choose Snow console will create and use a service-linked role to access Amazon resources on your behalf. to grant Amazon Snow Family permissions to use Amazon S3 and Amazon Simple Notification Service (Amazon SNS) on your behalf. The role grants Amazon Security Token Service (Amazon STS) AssumeRole trust to the Snow service

    • Choose Add an existing service role to use, to specify the Role ARN that you want, or you can use the default role.

    Example of Condition object to restrict Snow service actions

    Example of restricting Snow service actions by ARN and account IDs.

    "Condition": { "StringEquals": { "aws:SourceAccount": "AWS_ACCOUNT_ID" } "ArnLike": { "aws:SourceArn": "arn:aws:snowball:REGION:AWS_ACCOUNT_ID:RESOURCE_ID" } }

    The following shows these conditions included in a policy.

    { "Version": "2012-10-17", "Id": "__default_policy_ID", "Statement": [ { "Sid": "__default_statement_ID", "Effect": "Allow", "Principal": { "AWS": "*" }, "Action": [ "SNS:GetTopicAttributes", "SNS:SetTopicAttributes", "SNS:AddPermission", "SNS:RemovePermission", "SNS:DeleteTopic", "SNS:Subscribe", "SNS:ListSubscriptionsByTopic", "SNS:Publish" ], "Resource": "arn:aws-cn:sns:us-east-1:123456789012:my-sns-topic", "Condition": { "StringEquals": { "aws:SourceAccount": "111122223333" }, "ArnLike": { "aws:SourceArn": "arn:aws-cn:sns:us-east-1:555555555555:my-sns-topic" } } } ] }
    Example policies for Snowball Edge devices

    The following is an example of an Amazon S3 import-only role policy.

    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:GetBucketPolicy", "s3:GetBucketLocation", "s3:ListBucketMultipartUploads", "s3:ListBucket", "s3:PutObject", "s3:AbortMultipartUpload", "s3:ListMultipartUploadParts", "s3:PutObjectAcl", "s3:GetObject" ], "Resource": [ "arn:aws:s3:::DOC-EXAMPLE-BUCKET1", "arn:aws:s3:::DOC-EXAMPLE-BUCKET2/*" ] } ] }
    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "" }, "Action": "sts:AssumeRole" } ] }

    The following is an example of an IAM trust relationship for import and export role policies.

    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:GetBucketLocation", "s3:GetObject", "s3:ListBucket", "s3:GetBucketPolicy" ], "Resource": [ "arn:aws:s3:::DOC-EXAMPLE-BUCKET3/*", "arn:aws:s3:::DOC-EXAMPLE-BUCKET1/*" ] } ] }
    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "" }, "Action": "sts:AssumeRole" } ] }

    You can modify the trust relationship and restrict access to this role based on the customer account number and source arn. See Restricting Access to the Snow Role Policy on how to modify the trust relationship to restrict access.

  4. Choose Allow.
