1. How much will you invest in NIS2?
While improving security requires both time and financial investment, the rewards include a reduced risk of penalties (NIS2 does impose penalties), a lower likelihood of devastating security incidents, a competitive advantage, at least in the near term, and, most importantly, peace of mind.
2. Determine if You Are an Essential or Important Entity
The first key question is whether your organization qualifies as an essential or important entity. Essential entities operate in critical sectors where disruption would significantly impact public safety, national security, or the overall functioning of the economy and society. On the other hand, important entities could also face significant consequences if disrupted, but not to the same degree as essential entities. These are often businesses in less critical sectors or smaller organizations within critical industries.
3. Evaluate Your Supply Chain
The NIS2 Directive places a heavy emphasis on supply chain security, highlighting the risks posed by vulnerabilities in interconnected systems and third-party suppliers. It is crucial to assess where the critical dependencies in your supply chain lie and identify any weak points that could compromise your security.
4. Review Your Current Information Security Management System (ISMS)
Examine the current state of your Information Security Management System (ISMS). This includes evaluating your risk assessment processes, security measures, and business continuity procedures. Do you have any major gaps or weaknesses? Knowing where your vulnerabilities lie is crucial for compliance and improvement.
Once you’ve completed these initial evaluations, you can proceed with the detailed NIS2 checklist.
NIS2 Checklist
This checklist outlines key actions to take to align with the new requirements under the NIS2 Directive.
1. Assess Your Business Scope Under NIS2
NIS2 categorizes businesses into two groups, essential and important entities, based on sector, size, and societal importance. Assess where your business fits by reviewing the criteria (e.g., if you operate in critical sectors like energy, healthcare, or digital infrastructure).Understand the regulatory requirements for your entity type, as essential entities typically face more stringent obligations than important entities.
2. Establish Governance and Cybersecurity Roles
Appoint a Chief Information Security Officer (CISO) or an equivalent role to oversee NIS2 compliance. Management involvement is critical, as NIS2 increases accountability for senior management.Ensure senior management is actively involved in cybersecurity decisions and aware of their responsibilities under NIS2. The management team should sign off on all risk management strategiesSet up a cybersecurity governance structure that defines roles and responsibilities for incident reporting, risk management, and policy enforcement.
3. Conduct a Comprehensive Risk Assessment
Evaluate your organization’s critical information systems, networks, and supply chains to identify vulnerabilities to cyber threats. Analyze how potential disruptions could impact operations, considering both IT and OT systems.Conduct annual risk reviews to stay updated on emerging threats, organizational changes, and the introduction of new products or services. Keep in mind the potential business impact of any security incidents.Implement cybersecurity measures that are proportionate to the identified risks. This might include securing access controls, monitoring networks, and applying data encryption where appropriate.
4. Enhance Incident Detection, Response and Reporting Capabilities
Set up a system for detecting and reporting incidents. NIS2 requires you to report significant cybersecurity incidents within 24 hours of detection and provide a detailed report within 72 hours. Ensure you have tools and processes in place to meet these timelines. Create a detailed incident response plan that outlines the steps to take in the event of a cyber incident. This should include escalation processes, containment strategies, and communication protocols with clients in the energy sector. Regularly test and update your incident response plan to reflect new threats and regulatory changes. Establish communication channels with relevant national authorities (such as your country’s Computer Security Incident Response Team (CSIRT) to ensure you meet notification obligations.
5. Update Contracts and Supply Chain Security
Ensure cybersecurity in contracts. Review and update agreements with suppliers to include NIS2-compliant security requirements. This applies to both digital and physical supply chains. Supply chain vulnerabilities are a significant focus in NIS2, especially for critical infrastructure sectors like energy. Energy sector rely on numerous third-party suppliers, including vendors of operational technology (OT), IT systems, and other services. Establish mechanisms for monitoring and managing cybersecurity risks in your supply chain.
6. Cyber Security and Data Protection
Ensure that your IT infrastructure has robust security controls in place, such as encryption, identity management, and regular security updates.Comply with GDPR and NIS2 by ensuring all sensitive client data is encrypted both at rest and in transit. Apply data segmentation to limit the impact of potential data breaches.
7. Train and Educate Employees
Educate employees at all levels on the importance of cybersecurity, their role in maintaining security, and how to recognize potential threats (e.g., phishing). Ensure senior management is aware of their specific responsibilities under NIS2.
8. Prepare for Audits and Regulatory Oversight
Be ready for regular compliance checks from your sector’s supervisory authority. This may involve maintaining logs, performing internal audits, and preparing documentation to demonstrate compliance. Familiarize yourself with the potential penalties under NIS2. Non-compliance can lead to fines of up to €10 million or 2% of global turnover for essential entities.
9. Implement Continuous Monitoring and Improvement
Use cybersecurity tools that provide real-time monitoring and threat detection to stay on top of potential cyber threats. Continuously improve your cybersecurity framework by incorporating lessons from incidents, audits, and changes in the regulatory environment.
10. Reporting Obligations to Clients
If you are a vendor to the sector – In case of incidents affecting your systems, ensure your energy clients are informed immediately. Provide them with detailed updates and remediation plans within the timelines specified by NIS2.
Conclusion
For the energy sector, compliance with NIS2 is not just about meeting regulatory requirements; it’s about protecting critical infrastructure from the growing threat of cyberattacks. Focusing on supply chain security, incident response, governance, and business continuity are key areas where the energy sector must strengthen their operations. Given the high stakes, the energy sector need to adopt a proactive approach to cybersecurity, ensuring they are well-prepared for both the regulatory scrutiny and the evolving threat landscape.
