ISO 27001 and NIS2

Oct 14, 2024

A powerful combination for cybersecurity

In the rapidly evolving digital world, information security is a crucial aspect for every organization, likely including yours. Hackers are becoming increasingly active, and data theft is occurring more frequently. Two key pillars that play an indispensable role in cybersecurity are ISO 27001 and the new European NIS2 legislation. This blog provides a concise insight into how these guidelines help organizations improve their cybersecurity and comply with regulations.

What is ISO 27001?

To begin with: ISO 27001. This is an internationally recognized standard for information security management. ISO 27001 provides a framework for managing and protecting sensitive information through an Information Security Management System (ISMS). This certification helps organizations structure and improve their information security processes, enabling them to take measures to withstand cyber threats and data breaches.

What does NIS2 entail?

NIS2 (Network and Information Systems Directive) is a European cybersecurity legislation and successor to the original NIS Directive, introduced in 2016. This legislation focuses on raising the security level of network and information systems within the EU, especially in companies providing essential services such as energy, transport, and healthcare. The extension to NIS2, which goes into effect in July 2025, extends the scope to other sectors, such as the food industry, financial sector and public service. The following sectors are covered by NIS2:
  • Manufacturing
  • Energy
  • Transport
  • Banking
  • Financial market infrastructure
  • Healthcare
  • Drinking water
  • Digital infrastructure
  • ICT service providers
  • Wastewater
  • Government services
  • Local authorities
  • Space
  • Digital providers
  • Postal and courier services
  • Waste management
  • Food
  • Chemicals
  • Research
An important aspect of NIS2 is the emphasis on the responsibility of organizations to identify and address cybersecurity risks within their supply chain. This means that companies must not only secure their systems but also those of their partners and suppliers, covering the entire chain. The ultimate goal is to create a more resilient digital ecosystem, significantly reducing the likelihood of disruptions caused by cyberattacks.

How do ISO 27001 and NIS2 relate to each other?

While ISO 27001 and NIS2 operate in different areas, they complement each other well. ISO 27001 provides a robust framework for implementing and maintaining an ISMS, while NIS2 offers specific guidelines for sectors critical to national infrastructure.
Organizations in sectors covered by NIS2 can use ISO 27001 as a means to strengthen their information security practices and ensure they comply with broader, voluntary best practices for information security, in addition to the legal obligations of NIS2. Achieving ISO 27001 certification is already a significant step towards meeting the new NIS2 directive.

Synergies

  • Compliance and Certification: Companies already certified with ISO 27001 have a solid foundation for meeting NIS2 requirements, as many of the required controls and processes overlap.
  • Risk Management: Both frameworks emphasize risk management, with ISO 27001 providing a detailed approach to identifying and addressing risks, which is essential for meeting NIS2 requirements.

Implementation: steps and success factors

1. Management Involvement
Successful implementation starts with the support of top management. They must provide resources and support for the necessary changes.
2. Project Management
3. Training and Awareness
4. Continuous Improvement

A Powerful Combination

ISO 27001 and NIS2 together provide a powerful combination for strengthening information security within organizations. By complying with these standards and guidelines, companies can not only improve their security posture but also meet legal requirements, build trust with customers and partners, and gain a competitive advantage in the market. Implementation requires commitment and strategic planning, but the long-term benefits are significant.
