What this control requires
Source: NIST SP 800-171 R3 §03.16.01 (official control text).
Why this matters
Security engineering principles ensure systems are designed with protection built-in from the start, not bolted on afterward. This control requires organizations to embed security considerations throughout the entire system development lifecycle — from initial requirements through deployment and ongoing modifications. By applying layered defenses, threat modeling, secure coding practices, and architectural controls during design and development, organizations prevent vulnerabilities that would be exponentially more expensive to fix post-deployment. This approach reduces the attack surface, limits blast radius when breaches occur, and creates systems that fail securely rather than catastrophically when components are compromised.
What evidence assessors expect
Assessors typically look for: PDF, training certificate. FORCE coaches you through the exact implementation steps and captures each artifact in-platform.
