AWS Key Management Service or KMS uses envelope encryption which has a master key on top of a data key. Most noteworthy, the master key can decrypt and encrypt up to 4 KB of data.

Your data key is stored on disk with your encrypted data, but not before EBS encrypts it with your KMS key. Your data key never appears on disk in plaintext. The same data key is shared by snapshots of the volume and any subsequent volumes created from those snapshots if the volumes are encrypted using the same KMS key as the snapshot.

Use multi-factor authentication (MFA) with each account. Use SSL/TLS to communicate with AWS resources. We recommend TLS 1.3 or later. Set up API and user activity logging with AWS CloudTrail. Use AWS encryption solutions, along with all default security controls within AWS services. Use advanced managed security services such as Amazon Macie, which assists in discovering and securing personal data that is stored in Amazon S3.
