Question 1
A company is developing a highly resilient application to be hosted on multiple Amazon EC2 instances . The application will store highly sensitive user data in Amazon RDS tables
The application must
• Include migration to a different IAM Region in the application disaster recovery plan.
• Provide a full audit trail of encryption key administration events
• Allow only company administrators to administer keys.
• Protect data at rest using application layer encryption
A Security Engineer is evaluating options for encryption key management
Why should the Security Engineer choose IAM CloudHSM over IAM KMS for encryption key management in this situation?
- AOption A:
The key administration event logging generated by CloudHSM is significantly moreextensive than IAM KMS.
- BOption B:
CloudHSM ensures that only company support staff can administer encryption keys, whereas IAM KMS allows IAM staff to administer keys
- COption C:
The ciphertext produced by CloudHSM provides more robust protection against brute force decryption attacks than the ciphertext produced by IAM KMS
- DOption D:
CloudHSM provides the ability to copy keys to a different Region, whereas IAM KMS does not
Show answer and explanation
Correct answer: B
CloudHSM allows full control of your keys such including Symmetric (AES), Asymmetric (RSA), Sha-256, SHA 512, Hash Based, Digital Signatures (RSA). On the other hand, AWS Key Management Service is a multi-tenant key storage that is owned and managed byAWS1.
