ENCRYPTING AMAZON RDS RESOURCES

PDFRSS

Amazon RDS can encrypt your Amazon RDS DB instances. Data that is encrypted at
rest includes the underlying storage for DB instances, its automated backups,
read replicas, and snapshots.

Amazon RDS encrypted DB instances use the industry standard AES-256 encryption
algorithm to encrypt your data on the server that hosts your Amazon RDS DB
instances. After your data is encrypted, Amazon RDS handles authentication of
access and decryption of your data transparently with a minimal impact on
performance. You don't need to modify your database client applications to use
encryption.

NOTE

For encrypted and unencrypted DB instances, data that is in transit between the
source and the read replicas is encrypted, even when replicating across AWS
Regions.

OVERVIEW OF ENCRYPTING AMAZON RDS RESOURCES


Amazon RDS encrypted DB instances provide an additional layer of data protection
by securing your data from unauthorized access to the underlying storage. You
can use Amazon RDS encryption to increase data protection of your applications
deployed in the cloud, and to fulfill compliance requirements for encryption at
rest.

For an Amazon RDS encrypted DB instance, all logs, backups, and snapshots are
encrypted. Amazon RDS uses an AWS KMS key to encrypt these resources. For more
information about KMS keys, see AWS KMS keys in the AWS Key Management Service
Developer Guide and AWS KMS key management. If you copy an encrypted snapshot,
you can use a different KMS key to encrypt the target snapshot than the one that
was used to encrypt the source snapshot.

A read replica of an Amazon RDS encrypted instance must be encrypted using the
same KMS key as the primary DB instance when both are in the same AWS Region. If
the primary DB instance and read replica are in different AWS Regions, you
encrypt the read replica using the KMS key for that AWS Region.

You can use an AWS managed key, or you can create customer managed keys. To
manage the customer managed keys used for encrypting and decrypting your Amazon
RDS resources, you use the AWS Key Management Service (AWS KMS). AWS KMS
combines secure, highly available hardware and software to provide a key
management system scaled for the cloud. Using AWS KMS, you can create customer
managed keys and define the policies that control how these customer managed
keys can be used. AWS KMS supports CloudTrail, so you can audit KMS key usage to
verify that customer managed keys are being used appropriately. You can use your
customer managed keys with Amazon Aurora and supported AWS services such as
Amazon S3, Amazon EBS, and Amazon Redshift. For a list of services that are
integrated with AWS KMS, see AWS Service Integration.

Amazon RDS also supports encrypting an Oracle or SQL Server DB instance with
Transparent Data Encryption (TDE). TDE can be used with RDS encryption at rest,
although using TDE and RDS encryption at rest simultaneously might slightly
affect the performance of your database. You must manage different keys for each
encryption method. For more information on TDE, see Oracle Transparent Data
Encryption or Support for Transparent Data Encryption in SQL Server.


ENCRYPTING A DB INSTANCE


To encrypt a new DB instance, choose Enable encryption on the Amazon RDS
console. For information on creating a DB instance, see Creating an Amazon RDS
DB instance.

If you use the create-db-instance AWS CLI command to create an encrypted DB
instance, set the --storage-encrypted parameter. If you use the CreateDBInstance
API operation, set the StorageEncrypted parameter to true.

When you create an encrypted DB instance, you can choose a customer managed key
or the AWS managed key for Amazon RDS to encrypt your DB instance. If you don't
specify the key identifier for a customer managed key, Amazon RDS uses the AWS
managed key for your new DB instance. Amazon RDS creates an AWS managed key for
Amazon RDS for your AWS account. Your AWS account has a different AWS managed
key for Amazon RDS for each AWS Region.

For more information about KMS keys, see AWS KMS keys in the AWS Key Management
Service Developer Guide.

Once you have created an encrypted DB instance, you can't change the KMS key
used by that DB instance. Therefore, be sure to determine your KMS key
requirements before you create your encrypted DB instance.

If you use the AWS CLI create-db-instance command to create an encrypted DB
instance with a customer managed key, set the --kms-key-id parameter to any key
identifier for the KMS key. If you use the Amazon RDS API CreateDBInstance
operation, set the KmsKeyId parameter to any key identifier for the KMS key. To
use a customer managed key in a different AWS account, specify the key ARN or
alias ARN.

IMPORTANT

Amazon RDS can lose access to the KMS key for a DB instance. For example, RDS
loses access when the KMS key isn't enabled, or when RDS access to a KMS key is
revoked. In these cases, the encrypted DB instance goes into
inaccessible-encryption-credentials-recoverable state. The DB instance remains
in this state for seven days. When you start the DB instance during that time,
it checks if the KMS key is active and recovers the DB instance if it is.
Restart the DB instance using the AWS CLI command start-db-instance or AWS
Management Console.

If the DB instance isn't recovered, then it goes into the terminal
inaccessible-encryption-credentials state. In this case, you can only restore
the DB instance from a backup. We strongly recommend that you always turn on
backups for encrypted DB instances to guard against the loss of encrypted data
in your databases.


DETERMINING WHETHER ENCRYPTION IS TURNED ON FOR A DB INSTANCE


You can use the AWS Management Console, AWS CLI, or RDS API to determine whether
encryption at rest is turned on for a DB instance.

TO DETERMINE WHETHER ENCRYPTION AT REST IS TURNED ON FOR A DB INSTANCE

 1. Sign in to the AWS Management Console and open the Amazon RDS console at
    https://console.aws.amazon.com/rds/.

 2. In the navigation pane, choose Databases.

 3. Choose the name of the DB instance that you want to check to view its
    details.

 4. Choose the Configuration tab, and check the Encryption value under Storage.
    
    It shows either Enabled or Not enabled.
    
    


CONSOLE

TO DETERMINE WHETHER ENCRYPTION AT REST IS TURNED ON FOR A DB INSTANCE

 1. Sign in to the AWS Management Console and open the Amazon RDS console at
    https://console.aws.amazon.com/rds/.

 2. In the navigation pane, choose Databases.

 3. Choose the name of the DB instance that you want to check to view its

To determine whether encryption at rest is turned on for a DB instance by using
the AWS CLI, call the describe-db-instances command with the following option:

 * --db-instance-identifier – The name of the DB instance.

The following example uses a query to return either TRUE or FALSE regarding
encryption at rest for the mydb DB instance.

EXAMPLE

aws rds describe-db-instances --db-instance-identifier mydb --query "*[].{StorageEncrypted:StorageEncrypted}" --output text

parameter:

 * DBInstanceIdentifier – The name of the DB instance.


AVAILABILITY OF AMAZON RDS ENCRYPTION


Amazon RDS encryption is currently available for all database engines and
storage types, except for SQL Server Express Edition.

Amazon RDS encryption is available for most DB instance classes. The following
table lists DB instance classes that don't support Amazon RDS encryption:

Instance type Instance class

General purpose (M1)

db.m1.small

db.m1.medium

db.m1.large

db.m1.xlarge

Memory optimized (M2)

db.m2.xlarge

db.m2.2xlarge

db.m2.4xlarge

Burstable (T2)

db.t2.micro


ENCRYPTION IN TRANSIT


AWS provides secure and private connectivity between DB instances of all types.
In addition, some instance types use the offload capabilities of the underlying
Nitro System hardware to automatically encrypt in-transit traffic between
instances. This encryption uses Authenticated Encryption with Associated Data
(AEAD) algorithms, with 256-bit encryption. There is no impact on network
performance. To support this additional in-transit traffic encryption between
instances, the following requirements must be met:

 * The instances use the following instance types:
   
    * General purpose: M6i, M6id, M6in, M6idn, M7g
   
    * Memory optimized: R6i, R6id, R6in, R6idn, R7g, X2idn, X2iedn, X2iezn

 * The instances are in the same AWS Region.

 * The instances are in the same VPC or peered VPCs, and the traffic does not
   pass through a virtual network device or service, such as a load balancer or
   a transit gateway.


LIMITATIONS OF AMAZON RDS ENCRYPTED DB INSTANCES


The following limitations exist for Amazon RDS encrypted DB instances:

 * You can only encrypt an Amazon RDS DB instance when you create it, not after
   the DB instance is created.
   
   However, because you can encrypt a copy of an unencrypted snapshot, you can
   effectively add encryption to an unencrypted DB instance. That is, you can
   create a snapshot of your DB instance, and then create an encrypted copy of
   that snapshot. You can then restore a DB instance from the encrypted
   snapshot, and thus you have an encrypted copy of your original DB instance.
   For more information, see Copying a DB snapshot.

 * You can't turn off encryption on an encrypted DB instance.

 * You can't create an encrypted snapshot of an unencrypted DB instance.

 * A snapshot of an encrypted DB instance must be encrypted using the same KMS
   key as the DB instance.

 * You can't have an encrypted read replica of an unencrypted DB instance or an
   unencrypted read replica of an encrypted DB instance.

 * Encrypted read replicas must be encrypted with the same KMS key as the source
   DB instance when both are in the same AWS Region.

 * You can't restore an unencrypted backup or snapshot to an encrypted DB
   instance.

 * To copy an encrypted snapshot from one AWS Region to another, you must
   specify the KMS key in the destination AWS Region. This is because KMS keys
   are specific to the AWS Region that they are created in.
   
   The source snapshot remains encrypted throughout the copy process. Amazon RDS
   uses envelope encryption to protect data during the copy process. For more
   information about envelope encryption, see Envelope encryption in the AWS Key
   Management Service Developer Guide.

 * You can't unencrypt an encrypted DB instance. However, you can export data
   from an encrypted DB instance and import the data into an unencrypted DB
   instance.
