AWS Customer Master Keys (CMKs), now generally referred to as KMS keys, are encryption keys managed through AWS Key Management Service (KMS) used to encrypt and decrypt data across AWS services. They can be AWS-managed, customer-managed, or imported, giving organizations control over key policies, rotation, and access permissions. Security engineers use them to implement encryption at rest for services like S3, EBS, and RDS while meeting compliance requirements.
