Which feature is associated with FIPS 140-2 Level 3 security modules?

• A. Identity-based authentication, intrusion prevention, and critical access parameters
• B. Tamper-evident coatings
• C. Basic security features
• D. Erases all critical security information when tampered

Answer: (A)

FIPS 140-2 Level 3 emphasizes strong operator authentication and active protection against tampering, including controlled access to critical security parameters and a response to intrusion attempts. The best match is the option that explicitly mentions identity-based authentication for operators, intrusion prevention (reflecting tamper detection and response), and management of critical access parameters. These elements together reflect Level 3’s combination of authenticated user access, tamper detection/response, and protection of sensitive cryptographic material. In contrast, tamper-evident coatings align with Level 2, basic security features with Level 1, and while erasing all critical security information on tamper is related to Level 3, it does not alone capture the complete access-control and tamper-response aspects that Level 3 requires.
