According to CIP-008 R2.3, what should be done with records related to Reportable Cyber Security Incidents?

The correct answer emphasizes the importance of retaining records related to Reportable Cyber Security Incidents for future reference. This requirement aligns with the intent of CIP-008, which aims to ensure that organizations maintain an accurate and complete history of security incidents. Retaining these records is crucial for several reasons: it enables organizations to analyze past incidents, improve their security posture, develop better incident response strategies, and comply with regulatory expectations. Having a comprehensive archive of cyber incidents helps organizations recognize patterns, assess vulnerabilities, and enhance their overall cybersecurity framework.

In contrast, other options do not align with best practices for incident documentation. Archiving indefinitely may lead to issues with data management and privacy regulations, summarizing and sharing records publicly could expose sensitive information unnecessarily, and deleting them after review would eliminate valuable context and insight that could be beneficial for future incident handling and prevention efforts. Retention for future reference is a measured approach to ensure knowledge is preserved while still following regulatory requirements.
