CCSP Practice Question: Which THREE controls help protect data in use…
Which THREE controls help protect data in use within a cloud environment? (Choose three.)
⚠ Common exam trap
ISC2 often tests the distinction between data-at-rest, data-in-transit, and data-in-use controls, and the trap here is that candidates confuse tokenization (which protects data at rest) or access control lists (which protect data at rest/in transit) with technologies that specifically protect data during active processing in memory.
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
✓
Confidential computing
Confidential computing protects data in use by executing computations within a hardware-based Trusted Execution Environment (TEE), such as Intel SGX or AMD SEV, which isolates the data and code from the host operating system and hypervisor. This ensures that even privileged users or cloud administrators cannot access the plaintext data while it is being processed in memory.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Confidential computing
Why this is correct
Encrypts data in use in memory.
- ✗
Tokenization
Why it's wrong here
Protects data at rest by substitution.
- ✗
Access control lists
Why it's wrong here
Controls access but does not protect data in use.
- ✓
Secure enclaves (e.g., Intel SGX)
Why this is correct
Isolates data during processing.
- ✓
Homomorphic encryption
Why this is correct
Allows computation on encrypted data.
