Auditing ISO 27001 Annex A 5.5 Contact with Authorities ensures that an organization has established appropriate channels for regulatory reporting and incident notification. This process validates the Primary Implementation Requirement of maintaining maintained contact lists and defined trigger protocols for legal authorities. The Business Benefit mitigates legal risk and ensures rapid, compliant responses to security incidents or data breaches.
1. List of Relevant Regulatory Authorities Verified
Verification Criteria: A maintained register exists identifying all legal, regulatory, and supervisory bodies relevant to the organisation’s industry and jurisdiction.
Required Evidence: Legal and Regulatory Register or an “Authorities Contact List” within the ISMS documentation.
Pass/Fail Test: If the organisation cannot produce a list of specific authorities (e.g., ICO for UK GDPR, FCA for finance) relevant to their ISMS scope, mark as Non-Compliant.
2. Defined Trigger Points for Authority Notification Confirmed
Verification Criteria: Internal procedures explicitly define the specific security incidents or legal requirements that necessitate immediate contact with authorities.
Required Evidence: Incident Response Plan (IRP) or Data Breach Notification Policy containing specific “thresholds” for reporting.
Pass/Fail Test: If the documentation lacks binary criteria for when an incident must be escalated to an external body, mark as Non-Compliant.
3. Designated Liaison Personnel Identification Validated
Verification Criteria: Specific roles (e.g., DPO, CISO, Legal Counsel) are formally designated as the sole points of contact for interacting with authorities.
Required Evidence: Responsibility Assignment Matrix (RACI) or Job Descriptions specifying “Authority Liaison” duties.
Pass/Fail Test: If any staff member can contact a regulator regarding a security event without a formal internal approval path, mark as Non-Compliant.
