ISC Security Planning And Engineering Practice Question
When implementing FIPS 140-2/-3 validated cryptography in a system, what is the most important factor to verify?
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
✓
Verify the module is on the NIST CMVP validated list.
The cryptographic module must be explicitly listed on the CMVP (Cryptographic Module Validation Program) validated list, not just 'based on' an algorithm.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Ensure the vendor claims the product is FIPS compliant.
Why it's wrong here
Vendor claims are insufficient; independent validation is required.
- ✗
Ensure the product is open source.
Why it's wrong here
Open source status is irrelevant to FIPS validation.
- ✓
Verify the module is on the NIST CMVP validated list.
Why this is correct
Certification by NIST is the only way to ensure the module meets FIPS standards.
- ✗
Verify the algorithms are AES-256.
Why it's wrong here
Algorithm choice is important, but validation of the module is mandatory.
