What is the purpose of system lifecycle integration in RMF?

• A. Integrating RMF processes into the system engineering lifecycle from inception to retirement.
• B. Keeping RMF separate from development
• C. Applying RMF only during disposal
• D. Limiting RMF to post-implementation phase

Answer: (A)

Integrating RMF into the system life cycle means weaving risk management activities into every phase of a system’s life, from the earliest concept through design, development, operation, maintenance, and retirement. This ensures security controls are identified, implemented, tested, and authorized as the system evolves, and that ongoing monitoring keeps the risk posture accurate in the face of changing threats and system changes. The purpose is to integrate RMF processes into the system engineering lifecycle from inception to retirement.

If RMF is kept separate from development, risks aren’t addressed where they’re created, leading to more work later. If RMF is applied only during disposal or limited to the post-implementation phase, ongoing risk management and timely control updates during operation and maintenance are neglected, resulting in weaker security and potential compliance gaps.
