According to CIP-008 R1.2, what must be done when a Cyber Security Incident is identified?

When a Cyber Security Incident is identified, the requirement to notify the Electricity Sector Information Sharing and Analysis Center (ES-ISAC) within one hour is critical for ensuring a prompt response and information sharing among stakeholders in the electricity sector. This requirement emphasizes the importance of timely communication to mitigate the impact of the incident and facilitate coordinated efforts to address the threat.

Notifying the ES-ISAC quickly allows for a wider distribution of the information regarding the incident, fostering a collective response that can help other entities prepare or adjust their cybersecurity measures. The one-hour timeframe is a key aspect of this requirement, demonstrating the urgency of responding to cybersecurity incidents in an industry where disruptions can significantly impact operational integrity and public safety.

While other responses may involve important steps for an organization's internal processes, such as conducting investigations or maintaining confidentiality, the immediate notification to the ES-ISAC is a proactive measure designed to protect the broader infrastructure and enhance the resilience of the electricity sector against potential threats.
