CCSP Practice Question: Uses a cloud database service and needs to…
An organization uses a cloud database service and needs to protect data at rest. They enable Transparent Data Encryption (TDE) with a customer-managed key stored in the cloud provider's key management service. Which additional control should they implement to ensure the key cannot be used by unauthorized personnel?
⚠ Common exam trap
ISC2 often tests the distinction between preventive and detective controls, and candidates mistakenly choose audit logging (Option B) thinking it prevents unauthorized use, when it only records it after the fact.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement key rotation with a short rotation interval
Implementing key rotation with a short interval ensures that even if a customer-managed key is compromised or accessed by unauthorized personnel, the window of exposure is minimized. TDE with a customer-managed key in a cloud KMS relies on the key's secrecy; frequent rotation invalidates older key material, reducing the risk of long-term unauthorized decryption of data at rest.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable SSL/TLS for all database connections
Why it's wrong here
SSL/TLS protects data in transit, not at rest key access.
- ✗
Enable audit logging on key management operations
Why it's wrong here
Audit logs help detect but not prevent unauthorized use.
- ✓
Implement key rotation with a short rotation interval
Why this is correct
Regular key rotation limits the impact of a compromised key.
- ✗
Disable automatic key rotation and rely on manual rotation
Why it's wrong here
Manual rotation may be overlooked and does not provide automated security.
