ISO 27002 - Some examples

1. A.5.23 – Cybersecurity in Supplier Relationships

Real-world example:

• A manufacturing company now requires its cloud providers (AWS, Azure) to provide SOC 2 reports or security audits before onboarding.
• Action: Contractual clause mandating suppliers to report security breaches within 24 hours.

Best practices:

• Map third-party risks using a RACI matrix.
• Use tools like BitSight or SecurityScorecard to monitor partners.

2. A.8.28 – Management of Sensitive Data

Real-world example:

• A hospital implements automated labeling (e.g., "Confidential," "Internal") for medical records using solutions like Microsoft Purview.
• Action: Systematic encryption of sensitive data in transit (TLS 1.3) and at rest (AES-256).

Best practices:

• Deploy DLP (Data Loss Prevention) tools (e.g., Symantec, Forcepoint) to block leaks.
• Conduct quarterly audits of access to critical data.

3. A.8.10 – Threat Monitoring

Real-world example:

• A bank uses a SOC (Security Operations Center) with SIEM tools (Splunk or QRadar) for real-time attack detection.
• Action: Integrate a threat intelligence feed (e.g., MISP, Anomali) to anticipate ransomware.

Best practices:

• Annual penetration tests + Red Team/Blue Team exercises.
• Subscribe to threat bulletins (CERT-FR, MITRE ATT&CK).

4. A.8.11 – Data Masking

Real-world example:

• A software vendor masks test data in production using Oracle Data Masking or Delphix.
• Action: Replace real identifiers with aliases in development environments.

Best practices:

• Apply the least privilege principle (RBAC – Role-Based Access Control).
• Audit logs of access to masked data.

5. A.5.7 – Privacy and Protection of Personally Identifiable Information (PII)

Real-world example:

• An e-commerce platform conducts PIA (Privacy Impact Assessments) to comply with GDPR.
• Action: Explicit user consent before data collection.

Best practices:

• Encrypt data by default (Privacy by Design).
• Appoint a DPO (Data Protection Officer).
