Meeting New Cyber Incident Reporting Deadlines Under the NIS2 Directive

Introduction:

In previous articles, I provided an overview of the EU's new NIS2 Directive (1, 2 & 3) and its cybersecurity obligations for organizations like risk assessments and supply chain security. Now we will drill into NIS2's tighter incident reporting requirements.

Swift notification of cyber incidents enables rapid response and mitigation of threats before they can spread. However, reporting deadlines are drastically shorter under NIS2 compared to the original NIS Directive. It's crucial for organizations to understand these new obligations and prepare response processes. Smooth reporting facilitates overall NIS2 compliance.

NIS2 Incident Reporting Timeframes:

• 24 Hours: NIS2 requires “early warnings” of incidents be provided to relevant authorities within 24 hours of detection. These provide initial notification to mobilize a response.
• 72 Hours: A full incident notification with impact assessments and mitigation details must then be submitted within 72 hours of detection.
• Previous NIS Directive: The original NIS Directive had less stringent reporting requiring notifications based on subjective “undue delay” criteria.

The significantly tightened 24 and 72 hour hard deadlines under NIS2 mean organizations must have near real-time visibility into threats and efficient reporting procedures ready. We'll explore how organizations can meet these challenges next.

Details on New Reporting Expectations:

• Criteria - NIS2 defines “significant” incidents requiring reporting as those causing substantial operational disruption or financial losses, or affecting other legal entities.
• Early Warnings - Should include preliminary information like suspected cause, cross-border impacts, and need for assistance.
• Notifications - Provide incident summary, severity and impact assessments, mitigations applied, and risks to supply chain.
• Reporting Process - Notification templates and designated points of contact help streamline reporting to authorities.

Considerations for SMEs:

• Limited resources and expertise can make quick reporting difficult for SMEs.
• Leveraging IT/security providers can help with detection, analysis, and reporting.
• Prioritizing critical systems and data for monitoring eases incident identification.
• Basic security automation like intrusion detection systems can enable near real-time alerts.
• Focus reporting on incidents with greatest business impact.

Conclusion:

The significantly tighter NIS2 incident reporting deadlines mean organizations must have clear criteria, efficient processes, and security automation in place to detect and notify authorities swiftly.

While challenging, timely reporting is crucial for rapid response that contains threats and minimizes damage. Investing resources in incident detection and reporting capabilities will pay dividends through improved resilience.

For SMEs, focusing on quickly identifying and reporting incidents impacting core systems and data is key. Seek assistance from IT/security providers as needed.
