CAS-004 Security Engineering Practice Question
A security architect is evaluating hardware security modules (HSMs) for a new PKI deployment. The HSM must be compliant with FIPS 140-2 Level 3. Which of the following is a requirement for Level 3 that distinguishes it from Level 2?
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
✓
Identity-based authentication for operators
FIPS 140-2 Level 3 requires tamper-evident enclosures with active tamper response mechanisms (e.g., erasing keys) and identity-based authentication. Level 2 requires tamper-evident coatings or seals but not active response. Level 4 is more stringent.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Identity-based authentication for operators
Why this is correct
Level 3 requires identity-based authentication, whereas Level 2 only requires role-based authentication.
- ✗
Cryptographic boundary includes all critical components
Why it's wrong here
This is a general requirement for all levels.
- ✗
Environmental failure protections
Why it's wrong here
Environmental failure protections are part of Level 4, not Level 3.
- ✗
Physical security mechanisms that provide tamper evidence
Why it's wrong here
Tamper evidence is a Level 2 requirement, not unique to Level 3.
