How to Use ISO 27001 to Comply With NIS2 and DORA

The evolving regulatory landscape, with the introduction of NIS2 (Network and Information Systems Directive) and DORA (Digital Operational Resilience Act), requires organizations, particularly those operating critical infrastructure or within the financial sector, to align their security and operational practices with stringent requirements. ISO 27001:2022, the internationally recognized standard for information security management systems (ISMS), provides a robust framework to help organizations meet the expectations of these regulations.

This article explores how ISO 27001:2022 can be used to align with NIS2 and DORA through specific mapping and application strategies for critical infrastructure and financial organizations, as well as their suppliers.

1. Mapping ISO 27001 with NIS2

NIS2, a strengthened version of the original NIS Directive, applies to essential and digital service providers. Its focus is on improving cybersecurity capabilities, risk management, incident reporting, and information sharing for critical sectors such as energy, transport, and healthcare.

ISO 27001 can be effectively mapped to NIS2 requirements by following these steps:

  • Risk management: NIS2 emphasizes risk-based security practices. ISO 27001’s risk assessment (clause 6.1.2) and treatment processes (clause 6.1.3) are integral to identifying risks to critical information systems and applying appropriate controls.
  • Incident management: Both NIS2 and ISO 27001 focus on managing security incidents. Clause 16 of ISO 27001 deals with incident management procedures and can be tailored to meet NIS2’s requirements for reporting significant incidents to national authorities.
  • Supply chain security: NIS2 places greater responsibility on securing supply chains. ISO 27001 Annex A.15 addresses supplier relationships, ensuring that the security controls extend to third-party contractors and service providers.

By leveraging ISO 27001’s existing controls, organizations can systematically address the key components of NIS2, allowing them to ensure a holistic cybersecurity posture.

2. Using ISO 27001 for Critical Infrastructure Companies

For companies operating in critical infrastructure sectors, ISO 27001 provides a structured approach to meeting the stringent cybersecurity requirements of NIS2. Specifically, it aids in:

  • Establishing a risk-based approach: Critical infrastructure organizations are required to focus on preventing and managing cyber risks that can disrupt essential services. ISO 27001’s risk assessment process (Clause 6) ensures that organizations continuously identify, analyze, and mitigate risks associated with their operational environments.
  • Ensuring operational resilience: Annex A of ISO 27001 emphasizes business continuity and disaster recovery, which are vital for critical infrastructure. These align with NIS2’s requirements for maintaining operational resilience in the face of cyber incidents.
  • Maintaining compliance with reporting obligations: NIS2 requires timely and detailed reporting of security incidents. ISO 27001’s structured incident management (Clause 16) ensures that organizations have documented procedures to detect, report, and learn from security events.

ISO 27001 helps critical infrastructure organizations stay compliant with NIS2 while improving their overall security posture and operational resilience.

3. Using ISO 27001 for Suppliers of Critical Infrastructure Companies

Suppliers to critical infrastructure companies are also subject to NIS2 requirements. They must ensure that their security practices are robust enough to protect the supply chain. ISO 27001 is particularly valuable here:

  • Supply chain risk management: ISO 27001 Annex A.15 outlines specific requirements for managing risks associated with suppliers, helping them implement appropriate security controls across their relationships with critical infrastructure operators.
  • Compliance with client demands: Critical infrastructure companies often pass on compliance obligations to their suppliers. By implementing ISO 27001, suppliers can proactively demonstrate their commitment to security and regulatory compliance, fostering trust and ongoing partnerships.

ISO 27001 thus ensures that suppliers can meet the stringent security requirements expected by their clients under NIS2.

4. Mapping ISO 27001 with DORA

DORA (Digital Operational Resilience Act) applies to financial institutions and aims to ensure their ability to withstand cyber threats and operational disruptions. It emphasizes the need for robust cybersecurity, incident response, and third-party risk management.

ISO 27001 offers a practical framework that aligns well with DORA’s key requirements:

5. Using ISO 27001 for Financial Organizations

For financial institutions, ISO 27001 plays a crucial role in building a compliant and resilient cybersecurity framework:

  • Meeting DORA’s resilience requirements: Financial organizations are expected to have robust incident detection and response mechanisms under DORA. ISO 27001’s structured processes (Clause 16) ensure that organizations are prepared to detect, report, and respond to incidents, maintaining operational continuity.
  • Regulatory alignment: With DORA’s focus on governance, ISO 27001 ensures that financial organizations have the necessary security governance structure (Clause 5) in place, including roles, responsibilities, and accountability for information security management.

By adopting ISO 27001, financial institutions can align their information security frameworks with DORA’s rigorous operational resilience and risk management expectations.

6. Using ISO 27001 for Suppliers of Financial Organizations

Similar to critical infrastructure suppliers, suppliers of financial organizations face increased scrutiny under DORA. ISO 27001 helps these suppliers align with DORA’s requirements by:

  • Implementing robust security practices: ISO 27001 ensures that suppliers have standardized security practices, making them reliable partners for financial organizations and compliant with DORA’s supply chain resilience expectations.
  • Proactive risk management: Suppliers must identify, assess, and manage risks in their operations to avoid disruptions in services provided to financial organizations. ISO 27001’s risk management framework allows suppliers to continuously manage these risks in line with DORA.

By using ISO 27001, suppliers of financial organizations can ensure that they meet DORA’s operational and security demands, making them a valuable part of the financial ecosystem.

Conclusion

ISO 27001:2022 serves as a powerful tool for aligning with both NIS2 and DORA regulations. Whether for critical infrastructure companies or financial organizations, the ISO 27001 framework provides the necessary structure for risk management, incident response, and third-party security, enabling compliance with these new regulatory frameworks. Suppliers in both sectors also benefit from implementing ISO 27001, as it ensures they meet the heightened security and resilience demands of their clients under NIS2 and DORA.
