AWS Tutorial AWS Solutions Architect and SysOps Administrator - KMS Architecture

This lecture introduces AWS Key Management Service (KMS), explaining its role in securely generating and managing encryption keys for data encryption at rest. The architecture of KMS is detailed, highlighting how customer master keys and data keys are used to encrypt and decrypt data stored in AWS-managed storage devices. The process ensures data security by encrypting data keys and removing plaintext keys from temporary storage. The lecture concludes with a preview of creating and managing encryption keys in the next session.
