Understanding the Requirement: The company needs to control the creation, rotation, and disabling of encryption keys for data stored in S3 with minimal effort.

Analysis of Options:

SSE-S3: Provides server-side encryption using S3 managed keys but does not offer full control over key management.

Customer managed key with AWS KMS (SSE-KMS): Allows the company to fully control key creation, rotation, and disabling, providing a high level of security and compliance.

AWS managed key with AWS KMS (SSE-KMS): While it provides some control, it does not offer the same level of granularity as customer-managed keys.

EC2 instance encryption and re-upload: This approach is operationally intensive and does not leverage AWS managed services for efficient key management.

Best Solution:

Customer managed key with AWS KMS (SSE-KMS): This solution meets the requirement for full control over encryption keys with minimal operational overhead, leveraging AWS managed services for secure key management.
