What is required to be documented after verifying that cyber security controls are unaffected by a change?

Documenting the results of the verification process is critical as it serves as a formal record that confirms the integrity of cyber security controls after a change has been made. This documentation provides evidence that the controls were assessed and that they remain effective, which is crucial for maintaining compliance with NERC CIP standards.

By documenting the verification results, organizations can demonstrate due diligence and accountability in their cyber security practices. This becomes especially important during audits or assessments, where clear records of security control performance before and after changes are necessary to show adherence to regulatory requirements.

Keeping detailed records not only aids in tracking the effectiveness of security measures but also helps facilitate ongoing risk management and continuous improvement of the security posture. Documenting changes and their verification ensures all stakeholders are aware of the current state of the cyber security controls and can make informed decisions moving forward.
