The ISO 27001 ISMS auditor pressure-tests any ISMS work. Six sample-driven questions before any internal audit, stage 1 readiness, or surveillance audit.

When to Run

  • Before annual Clause 9.2 internal audit
  • Before stage 1 / stage 2 ISO 27001 certification audit
  • Before surveillance audit (year 2 / year 3)
  • After material change to ISMS scope (new business unit, new product line, new SaaS adoption)
  • Post-incident (breach triggers ad-hoc ISMS audit)
  • Quarterly during high-growth phase

The Six ISMS Questions

1. What's the audit scope, and is rolling 3-year coverage on track?

No 3-year coverage discipline, no defensible programme. - Every Clause 4-10 + every applicable Annex A control must be audited at least once per 3-year cycle - Run isms_audit_scheduler.py in ra-qm-team/skills/isms-audit-expert/ - Confirm auditor independence — no self-audit on any sample

2. When was the risk register last refreshed, and are treatments linked to Annex A controls?

Stale risk register = certification finding. - Quarterly refresh expected; annual minimum - Every high/critical risk must link to ≥ 1 Annex A control treating it - Residual risk acceptance documented + signed - Review against iso27001_audit_playbook.md for stage 1 expectations

3. Show me the access review records — quarterly cadence, the last 4 quarters.

Most-cited finding area. - Annex A.5.15 + A.8.2 + A.8.3 access controls - Sample real records pulled from Okta / IAM, not curated audit-prep packs - For each terminated employee in last 90 days: deprovisioning evidence within 24-hour SLA - Privileged access reviewed at finer granularity

4. What's the supplier inventory + last review evidence?

Second-most-cited finding area. - Annex A.5.19-A.5.21 supplier management - Critical SaaS suppliers reviewed at least annually - DPAs signed for personal-data sub-processors (cross-check with cs-dpo-gdpr) - AI-specific contract clauses where third-party AI services in use (cross-check with cs-aims-iso42001)

5. Where's the incident response evidence + post-incident review?

A.5.24-27 + A.6.8 — high-stakes audit area. - Severity definitions documented + consistently applied - Last 5 incidents have post-incident review (PIR) within 30-day SLA - GDPR Article 33 / 34 notification timing aligned with A.5.24 (cross-check with cs-dpo-gdpr) - Blameless retro culture; not punitive

6. What's the management review cadence + inputs?

Clause 9.3 required inputs are prescriptive — easy to miss. - Required inputs: audit results, risks, performance, nonconformities, opportunities - Schedule: annual minimum; quarterly preferred for mature programs - Outputs documented + tracked to closure - Integrated review across frameworks (per multi_framework_audit_playbook.md) preferred to separate reviews

Workflow

# 1. Audit programme planning
python ../../ra-qm-team/skills/isms-audit-expert/scripts/isms_audit_scheduler.py audit_scope.json

# 2. Mock audit for readiness check
python ../../skills/compliance-os/scripts/audit_simulator.py iso27001_scope.json

# 3. Cross-framework reuse (SOC 2 = 75% overlap; ISO 42001 = 60% reuse)
python ../../skills/compliance-os/scripts/cross_framework_mapper.py program.json
