How long does the Responsible Entity have to implement a mitigation plan after its creation or revision?

The correct choice indicates that a Responsible Entity has a specific timeframe to implement a mitigation plan after its creation or revision, which is set at 35 calendar days. This requirement ensures that identified risks are addressed in a timely manner, maintaining the integrity and security of critical infrastructure.

The 35-day timeframe is designed to emphasize the importance of swift action in addressing vulnerabilities, which can arise from various factors such as equipment failures, cyber threats, or other security concerns. This prompt implementation is crucial for maintaining compliance with the NERC Critical Infrastructure Protection (CIP) standards, protecting essential services and ensuring reliability in the electric grid.

Timely execution of mitigation plans is vital since delays can expose the entity to extended risks and potential failures in their critical infrastructure protection systems. This requirement not only promotes proactive risk management but also fosters a culture of accountability within the organization about the security measures taken to safeguard assets.
