Which outcome describes updating security and privacy plans to reflect control implementation changes made based on the assessments and remediation actions?

• A. Remediation actions to address deficiencies in the controls implemented in the system and environment of operation are taken.
• B. Security and privacy plans are updated to reflect control implementation changes made based on the assessments and remediation actions.
• C. A plan of action and milestones detailing remediation plans for unacceptable risks identified in security and privacy assessment reports is developed.
• D. Ongoing assessments of control effectiveness are conducted.

Answer: (B)

Keeping security and privacy plans current after control changes is essential. When assessments identify gaps and remediation actions are implemented, updating the plans to reflect those control implementation changes ensures the documentation accurately mirrors the actual security posture. This alignment is crucial for ongoing authorizations, risk management, and clear accountability, so stakeholders and auditors see exactly what controls are in place, how they were changed, and why.

Other options describe actions taken or documents used in the process, but they don’t capture the step of updating the plans themselves to reflect the new control state.
