What is the initial notification timeframe for Reportable Cyber Security Incidents?

The correct initial notification timeframe for Reportable Cyber Security Incidents is one hour. This stringent requirement reflects the urgency and critical nature of cybersecurity threats in the context of critical infrastructure, ensuring that entities can quickly address potential risks. Timely notifications allow for an immediate assessment of the situation and facilitate coordinated responses, both internally and with relevant stakeholders or regulatory bodies.

The one-hour requirement ensures that organizations prioritize incident reporting in alignment with NERC CIP standards, which are designed to safeguard the reliability of the grid and protect sensitive information from cyber threats. This rapid notification can be crucial in mitigating the impacts of a cyber incident and helps maintain the overall security posture of the affected organization.
