Exam AWS Certified SysOps Administrator - Associate topic 1 question 284 discussion

A company is building an interactive application for personal finance. The application stores financial data in Amazon S3, and the data must be encrypted. The company does not want to provide its own encryption keys. However, the company wants to maintain an audit trail that shows when an encryption key was used and who used the key.

Which solution will meet these requirements?

  • A. Use client-side encryption with client-provided keys. Upload the encrypted user data to Amazon S3.
  • B. Use server-side encryption with S3 managed encryption keys (SSE-S3) to encrypt the user data on Amazon S3.
  • C. Use server-side encryption with customer-provided encryption keys (SSE-C) to encrypt the user data on Amazon S3.
  • D. Use server-side encryption with AWS KMS managed encryption keys (SSE-KMS) to encrypt the user data on Amazon S3.

Selected Answer: D
While SSE-S3 is convenient, it doesn't allow the company to have control over key management or maintain a detailed audit trail for key usage. AWS KMS provides detailed audit logs through AWS CloudTrail, which allows you to monitor and log all API calls related to key usage

Answer D: with SSE-KMS, you have more control over your keys than you do with SSE-S3. For example, you can follow the keys in AWS Cloud Trail.
