What should a solutions architect recommend to satisfy these requirements?
Server-side encryption with customer-provided encryption keys
Client-side encryption with Amazon S3 managed encryption keys
Server-side encryption with keys stored in AWS key Management Service (AWS KMS)
Client-side encryption with a master key stored in AWS Key Management Service (AWS KMS)
Explanations:
Server-side encryption with customer-provided keys (SSE-C) encrypts data on AWS side, not before sending, which fails to meet the requirement for pre-encryption.
Client-side encryption with Amazon S3 managed keys does not fulfill the requirement, as Amazon S3 managed keys handle encryption on the server side, not on the client side.
Server-side encryption with AWS KMS also encrypts data after it reaches Amazon S3, rather than encrypting it before sending, which does not meet the requirement.
Client-side encryption with a master key stored in AWS KMS ensures encryption is handled by the client before data is transmitted to S3, fully satisfying the security compliance requirements.
