ISO/IEC 27002:2022 provides a comprehensive framework for implementing information security controls, serving as a practical guide for organizations aiming to achieve ISO/IEC 27001 certification. This standard outlines best practices for managing cybersecurity risks, ensuring data confidentiality, integrity, and availability.
You Should Know:
Key Security Controls in ISO/IEC 27002:2022
1. Access Control (A.9)
- Implement role-based access control (RBAC):
sudo usermod -aG <group> <username> Add user to a group in Linux
- Restrict root access:
sudo nano /etc/ssh/sshd_config Set PermitRootLogin no
2. Cryptography (A.10)
- Encrypt files using OpenSSL:
openssl enc -aes-256-cbc -salt -in file.txt -out file.enc
- Verify file integrity with SHA-256:
sha256sum file.iso
3. Incident Management (A.16)
- Monitor logs with
journalctl:journalctl -u sshd --no-pager | grep "Failed password"
- Isolate compromised systems:
iptables -A INPUT -s <malicious_IP> -j DROP
4. Network Security (A.13)
- Scan open ports with
nmap:nmap -sV <target_IP>
- Harden firewalls using
ufw:sudo ufw enable && sudo ufw default deny incoming
5. Malware Protection (A.12)
- Scan for malware with
ClamAV:sudo clamscan -r /home
- Automate scans with
cron:crontab -e Add: 0 3 clamscan -r / >> /var/log/clamav.log
Steps to Implement ISO/IEC 27002:2022
1. Risk Assessment
- Use `Lynis` for Linux auditing:
sudo lynis audit system
2. Policy Development
- Document controls in
/etc/policies/.
3. Employee Training
- Conduct phishing simulations with
GoPhish.
4. Continuous Monitoring
- Deploy `OSSEC` for real-time alerts:
sudo ossec-control start
What Undercode Say
ISO/IEC 27002:2022 is a critical roadmap for cybersecurity resilience. By integrating these controls with automated tools like `fail2ban` for brute-force protection and `AIDE` for file integrity monitoring, organizations can significantly reduce attack surfaces. Future advancements in AI-driven threat detection will further align with these standards, making compliance dynamic rather than static.
Expected Output:
- Hardened Linux systems via `chmod 600` for sensitive files.
- Encrypted backups using
gpg --encrypt. - Regular `nmap -Pn` scans to detect unauthorized devices.
- Automated `logwatch` reports for security events.
Prediction
AI-powered compliance tools will soon automate 80% of ISO 27002 control assessments, reducing manual audits by 2026.
