Introduction

Cybersecurity threats evolve daily, and no organization can face them alone. ISO 27001 Control 5.6 recognizes the power of collaboration by encouraging organizations to maintain contact with relevant special interest groups (SIGs) such as industry associations, security forums, and threat intelligence networks.

The goal is to share knowledge, stay ahead of threats, and strengthen your defense posture.

Control Objective

To ensure your organization benefits from shared security knowledge and early warnings by maintaining relationships with recognized special interest groups, industry peers, and professional forums.

Implementation Guidance

1) Identify Relevant SIGs:

• Examples:
  • National cybersecurity centers (e.g. CSE’s Canadian Centre for Cyber Security)
  • Industry-specific alliances (e.g. Financial ISAC, Health ISAC)
  • Professional associations (e.g. ISACA, (ISC)², InfraGard)
  • Local cybersecurity meetups and working groups

2) Assign Participation Responsibility:

• Designate representatives to attend meetings, monitor updates, and relay relevant intelligence internally

3) Integrate Insights into Security Operations:

• Use shared threat intel for patch prioritization, awareness campaigns, and incident detection

4) Maintain Active Engagement:

• Don’t just join  contribute knowledge, participate in working groups, and share best practices

5) Document and Review Memberships:

• Keep track of memberships, participation level, and value delivered to your security posture

Why This Control Matters

Special interest groups can provide:

• Early warnings of emerging threats
• Best practices from experienced peers
• Regulatory updates and interpretations
• A trusted network for knowledge exchange

This collaboration strengthens your threat intelligence and resilience while aligning with ISO 27001’s continuous improvement principles.

Common Pitfalls to Avoid

• Passive membership without real engagement
• Joining irrelevant groups that don’t provide actionable value
• Not sharing intelligence with the right internal stakeholders
• Letting memberships lapse unnoticed
