This process validates the Primary Implementation Requirement of maintaining a formally approved, topic-specific policy framework.

1. High-Level Information Security Policy Approval Verified
Verification Criteria: The primary Information Security Policy must be formally approved by top management, demonstrating leadership commitment to the ISMS.
Required Evidence: Signed policy document or Management Review Meeting (MRM) minutes explicitly recording the board-level approval of the current policy version.
Pass/Fail Test: If the policy lacks a formal signature, digital approval stamp, or corresponding minute-entry from executive leadership, mark as Non-Compliant.
2. Topic-Specific Policy Architecture Validated
Verification Criteria: A comprehensive suite of topic-specific policies (e.g., Access Control, Cryptography, Physical Security) exists to support the high-level policy as defined by the ISMS scope.
Required Evidence: Document register showing a structured hierarchy of active, approved topic-specific policies.
Pass/Fail Test: If significant control areas identified in the Statement of Applicability (SoA) lack supporting topic-specific documentation, mark as Non-Compliant.
3. Policy Accessibility for Relevant Personnel Confirmed
Verification Criteria: All policies must be published in a format and location (e.g., Intranet, DMS) that is accessible to all employees and contractors within the ISMS scope.
Required Evidence: Live demonstration of the policy repository and verification of “Read Only” access permissions for general staff.
Pass/Fail Test: If policies are stored in a restricted folder inaccessible to the staff expected to follow them, mark as Non-Compliant.
