ISO 27001 Contact with Special Interest Groups Implementation Checklist
Use this implementation checklist to achieve compliance with ISO 27001 Annex A 5.6. This control ensures your organisation isn’t operating in a vacuum by maintaining active connections with security communities for threat intelligence and best practice sharing.
1. Define Your Intelligence Needs
Control Requirement: The organisation must maintain contact with special interest groups to receive relevant security information.
Required Implementation Step: create a simple scope document defining what “intelligence” you actually need (e.g., “We need AWS vulnerability alerts and Fintech fraud updates”).
Minimum Requirement: A single statement in your policy defining the types of external information relevant to your business risks.
2. Identify Professional Bodies
Control Requirement: Participation in professional associations is required to stay current with industry standards.
Required Implementation Step: List the professional memberships held by your team (e.g., ISACA, ISSA, IAPP) that provide access to security journals and conferences.
Minimum Requirement: Identify at least one professional security body your team follows or belongs to.
3. Identify Technical Forums
Control Requirement: Access to specialist security information and early warnings.
Required Implementation Step: specific links to the technical forums your developers or engineers use (e.g., OWASP, Reddit r/netsec, vendor community forums).
Minimum Requirement: A list of 2-3 technical sources where your engineering team checks for vulnerability discussions.
