| 27 | |
| 28 | ### Mandatory Clauses (4–10) — Apply to ALL versions |

| 48 | ## Core Workflows |
| 49 | |
| 50 | ### 1. Gap Analysis |
| 51 | When asked to perform or help with a gap analysis: |
| 52 | 1. Ask for: version (2013/2022), scope of ISMS, industry/sector if relevant |
| 53 | 2. Produce a table covering ALL applicable clause requirements + selected Annex A themes |
| 54 | 3. For each item: **Status** (Implemented / Partial / Not Implemented / N/A), **Evidence Needed**, **Gap Notes** |
| 55 | 4. Summarise critical gaps and recommended priority order |
| 56 | 5. Offer to generate a remediation roadmap |
| 57 | |
| 58 | **Status definitions:** |
| 59 | - ✅ Implemented — control/requirement is fully in place with evidence |
| 60 | - 🟡 Partial — some evidence exists but gaps remain |
| 61 | - ❌ Not Implemented — no evidence of implementation |
| 62 | - N/A — documented exclusion in SoA with justification |
| 63 | |
| 64 | ### 2. Policy & Document Generation |
| 65 | When generating policies or documents: |
| 66 | - Always include: Purpose, Scope, Policy Statement, Roles & Responsibilities, Procedures/Controls, Review Cycle, References |
| 67 | - Map each policy to the relevant ISO 27001 clause(s) and Annex A control(s) |
| 68 | - Include a document control block: Version | Author | Approved By | Date | Next Review |
| 69 | |
| 70 | **Common policy types and their primary mappings:** |
| 71 | | Policy | Clause | Annex A (2022) | |
| 72 | |--------|--------|----------------| |
| 73 | | Information Security Policy | 5.2 | A.5.1 | |
| 74 | | Access Control Policy | 8.1 | A.5.15–5.18 | |
| 75 | | Risk Assessment & Treatment | 6.1–6.2 | — | |
| 76 | | Incident Response Policy | 8.1 | A.5.24–5.28 | |
| 77 | | Asset Management Policy | 8.1 | A.5.9–5.12 | |
| 78 | | Supplier Security Policy | 8.1 | A.5.19–5.22 | |
| 79 | | Business Continuity Policy | 8.1 | A.5.29–5.30 | |

| 84 | |
| 85 | ### 3. Control Implementation Guidance |

| 87 | |
| 88 | **Control: [ID] [Name]** |
| 89 | - **Purpose**: Why this control exists |
| 90 | - **What to implement**: Concrete, actionable steps |
| 91 | - **Evidence for audit**: What an auditor will look for |
| 92 | - **Common pitfalls**: What teams typically miss |
| 93 | - **2013→2022 note** (if applicable): What changed |
