Aligning NIS2 with ISO/IEC 27001:2022 for Enhanced Cybersecurity Compliance

By /

Featured Image
The NIS2 Directive introduces broad cybersecurity obligations with complex legal terminology, often lacking concrete implementation guidance. Instead of starting from scratch, organizations can leverage the well-established ISO/IEC 27001:2022 and ISO/IEC 27002 frameworks to streamline compliance.

Key Benefits of Aligning NIS2 with ISO 27001

  1. Mapping NIS2 Requirements to ISO Controls – Identify overlaps and gaps.
  2. Leveraging Existing Security Measures – Avoid redundancy by using current ISO 27001 implementations.
  3. Prioritizing Critical Actions – Focus on high-impact security improvements.
  4. Saving Time & Resources – Reduce duplication and strengthen security efficiently.

You Should Know: Practical Steps for NIS2-ISO Alignment

1. Conduct a Gap Analysis

  • Compare NIS2 requirements against your existing ISO 27001 controls.
  • Use ISO 27002:2022 for detailed implementation guidance.

Linux Command Example (Auditing Compliance):

 Use Lynis for security auditing 
sudo apt install lynis -y 
sudo lynis audit system

2. Strengthen Access Controls

  • NIS2 emphasizes strict access management.

Windows Command Example (Check User Permissions):

 List users with administrative privileges 
net localgroup administrators

3. Enhance Incident Response

  • Align NIS2 incident reporting with ISO 27001’s A.16.1.7 (Collection of Evidence).

Linux Command Example (Log Monitoring):

 Monitor auth logs for suspicious activity 
tail -f /var/log/auth.log | grep "Failed password"

4. Implement Continuous Monitoring

  • Use SIEM tools (e.g., Wazuh, Elastic SIEM) for real-time threat detection.

Linux Command Example (Install Wazuh Agent):

curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | sudo gpg --no-default-keyring --keyring gnupg-ring:/usr/share/keyrings/wazuh.gpg --import && sudo chmod 644 /usr/share/keyrings/wazuh.gpg 
echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | sudo tee /etc/apt/sources.list.d/wazuh.list 
sudo apt update && sudo apt install wazuh-agent

What Undercode Say

NIS2 compliance doesn’t require reinventing the wheel—ISO 27001:2022 provides a proven foundation. By mapping NIS2 obligations to existing ISO controls, organizations can:
– Reduce compliance costs
– Improve security maturity
– Avoid audit fatigue

Additional Linux Commands for Security Hardening:

 Check open ports (NIS2 mandates network security) 
sudo ss -tulnp

Verify file integrity (NIS2 Art. 21 - Supply Chain Security) 
sudo sha256sum /critical/file.txt

Enforce password policies (NIS2 Art. 18 - Access Control) 
sudo apt install libpam-pwquality 
sudo nano /etc/security/pwquality.conf

Windows Command for Patch Compliance (NIS2 Art. 10 – Vulnerability Management):

 List missing security updates 
Get-WindowsUpdate -Install -AcceptAll -AutoReboot

Expected Output:

A structured, compliant cybersecurity framework that meets NIS2 requirements while leveraging ISO 27001:2022 best practices.

Prediction

As regulatory pressures intensify, more organizations will adopt automated compliance tools (e.g., OpenSCAP, Wazuh) to bridge NIS2 and ISO 27001, reducing manual effort and improving audit readiness.
