In RMF, which step involves implementing the security controls selected for the information system?

• A. Categorize
• B. Select
• C. Implement
• D. Authorize

Answer: (C)

In RMF, once you’ve selected the appropriate security controls for the system, the next step is to put those controls into operation. Implementing means actually applying, configuring, and wiring in the chosen safeguards so they are active within the system environment. This includes installing and configuring security features, enforcing access controls, setting up encryption, logging and monitoring capabilities, patching, and documenting the configurations in the system’s security plan. Without this active deployment, the controls exist only on paper; they must be implemented to become effective and to be evaluated in the subsequent assessment phase. This step sits between selecting the controls and assessing their effectiveness, and it precedes the authorization decision and ongoing monitoring. The other steps involve categorizing the system (defining impact), selecting which controls to use (based on risk), assessing how well the controls are implemented and functioning, authorizing operation to proceed, and continuously monitoring the security posture.
