What the auditor wants to verify

Audit objective

This is the core audit assertion. Evidence should prove design, implementation, and operation.

The auditor wants to confirm that the organization maintains proportionate contact with relevant specialist security groups, forums, or professional associations and that useful information is shared internally and used to improve the ISMS.

Evidence to request

Evidence Purpose
Special interest group register Shows groups are identified, justified, and owned
Membership or subscription records Shows participation exists
Meeting, webinar, or conference attendance records Shows active engagement
Security briefing notes Shows information is distributed internally
Advisory triage records Shows external information is reviewed
Risk register updates Shows information affects risk decisions
Control or procedure updates Shows learning is converted into action
NDA or forum participation rules Shows confidential sharing is controlled
Management reports Shows significant external insights reach decision-makers

Strong evidence

Strong evidence test

Prefer dated, owned, reviewed records that show the control operated for real cases.

  • Group register includes purpose, owner, relevance, participation method, and review date.
  • External information is triaged and distributed to relevant internal stakeholders.
  • Participation has influenced risk assessment, controls, awareness, or procedures.
  • Staff understand confidentiality rules for external forums.
  • Management receives relevant summaries from external security sources.

Weak evidence

Weak evidence warning

Weak evidence usually shows a document exists but does not prove operation or effectiveness.

  • Membership exists but no one participates.
  • Staff follow informal sources with no process.
  • No record of how information is shared internally.
  • No rule preventing confidential disclosure.
  • External groups are unrelated to the organization’s risk profile.
  • No evidence that external learning affects decisions.

Sample interview questions

Ask security leadership

  • Which specialist groups or professional associations are relevant?
  • Why were those groups selected?
  • How is information from those groups reviewed?
  • How does useful information reach management or control owners?
  • How do you decide whether participation remains worthwhile?

Ask participants

  • What information do you receive from the group?
  • What are you allowed to share externally?
  • How do you distribute useful information internally?
  • Can you give an example of a change made because of external input?

Ask control owners

  • Do you receive security updates from external groups?
  • Have external advisories affected your controls or procedures?

Common nonconformities

  • No relevant external security contacts.
  • Participation not proportionate to risk or sector.
  • No internal sharing process.
  • Confidential information can be disclosed without authorization.
  • External information is not used in risk or control decisions.
  • No review of membership value or relevance.
