Contact with Special Interest Groups
Plain English Translation
ISO 27001 A.5.6 requires organizations to actively participate in the wider security community. Instead of operating in isolation, your team should maintain memberships in professional associations (like ISACA or ISC2) and subscribe to security forums or industry groups. This ensures you receive early warnings about new threats, stay updated on best practices, and have a network of experts to consult during security incidents.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Subscribe to free government alerts (e.g., CISA, NCSC)
- Follow reputable security researchers and vendors on social channels
Required Actions (scaleup)
- Pay for memberships in professional organizations (ISACA, ISC2) for key staff
- Join industry-specific Information Sharing and Analysis Centers (ISACs)
Required Actions (enterprise)
- Sponsor security conferences and encourage staff to present
- Establish formal data-sharing partnerships with national CERTs
It is an organizational control requiring contact with special interest groups and professional associations to ensure the organization stays informed about the latest security trends, threats, and best practices.
Implementation involves identifying relevant groups (like ISACA, OWASP, or industry ISACs), funding memberships for staff, and verifying that information from these groups is actually reviewed and used. WatchDog Security's Compliance Center can help document ownership, review frequency, and the evidence trail showing that alerts were assessed.
Relevant groups include professional associations (ISC, ISACA), government bodies (CISA, NCSC), industry-specific forums (Financial Services ISAC), and vendor security notifications.
Auditors expect to see evidence such as receipts for membership fees, screenshots of email subscriptions (e.g., US-CERT), or certificates of attendance at security conferences. WatchDog Security's Compliance Center can organize these artifacts by control and flag missing items ahead of an audit.
Benefits include access to expert advice during incidents, early warnings of vulnerabilities (threat intelligence), and professional development for the security team. WatchDog Security's Risk Register can help convert recurring external intelligence themes into tracked risks with owners and planned treatments.
A.5.6 provides the *channels* and *relationships* through which threat intelligence (A.5.7) is often acquired; the groups provide the raw data and context that becomes intelligence.
Engagement should be continuous, with subscriptions monitored regularly (e.g., weekly) and memberships renewed annually to ensure information remains current.
A.5.6 focuses on establishing *relationships* and *communication channels* with external groups, whereas A.5.7 focuses on the process of *collecting and analyzing* the actual threat data obtained.
External advisories often get missed because there is no consistent triage workflow or ownership once an alert is received. WatchDog Security's Vulnerability Management can help intake findings from multiple sources, assign owners, and track remediation timelines, while WatchDog Security's Risk Register can capture higher-level themes (e.g., recurring exposure areas) as risks with treatment plans and reporting.
Auditors typically want evidence of more than paid memberships—they look for a repeatable process showing reviews, decisions, and follow-up. WatchDog Security's Compliance Center can track required artifacts (membership records, subscription lists, review logs) and highlight gaps, making it easier to demonstrate that information from special interest groups is reviewed and integrated into security operations.
