🧾 ISO 27001:2022 — Annex A Reference (Summary)

ISO 27001:2022 Annex A controls are organized into four themes. Use this mapping when designing policy and control sets.

Theme	Description	# Controls (approx)
A.5	Organizational Controls (policies, roles, governance)	~37
A.6	People (HR security, awareness, segregation of duties)	~8
A.7	Physical (facilities, physical access)	~14
A.8	Technological (access control, crypto, logging, network)	~34

Note: When mapping to your organization, replace approximate counts with actual Annex A clause references used in the 2022 standard.

(Detailed samples and templates — these are ready to paste into your internal documents or Confluence pages.)

Gap Analysis Report — Sub-categories & Sample

1. Approach & Methodology

Assessment against ISO 27001:2022 Annex A controls using interviews, document review, configuration review, and technical walkthroughs. Scoring performed using a 1–5 maturity scale (1 = Not implemented, 5 = Optimized).

2. Gap Summary Table (Sample)

Control ID	Control Description	Current Status	Gap Identified	Recommendation	Owner	Target Date
A.5.1	Information Security Policy	Partially Implemented	Policy outdated (2018 structure)	Revise policy to align with ISO 27001:2022 structure & obtain management sign-off	IT Security	30-Nov-2025
A.6.3	Security Awareness	Not Implemented	No formal program, no LMS records	Launch quarterly awareness & phishing simulation program	HR / IT Security	15-Dec-2025
A.8.15	Logging & Monitoring	Implemented (partial)	SIEM use-cases not covering cloud tenants	Extend SIEM and implement cloud connectors & runbooks	Infra Team	31-Jan-2026

3. Maturity Scoring (Sample)

Area	Score (1–5)	Notes
Policy & Governance	3	Policies exist but need update & approval
Operations & Monitoring	3	Basic logging; cloud coverage gaps
Awareness & Training	2	No structured program

4. Key Observations

• No centralized risk register — risk recorded in spreadsheets only.
• Identity & access management requires PAM for privileged accounts.
• Vendor risk evaluations are ad-hoc and not integrated into procurement.

5. Recommendations Summary

• Implement a central Policy Repository (Confluence with versioning).
• Onboard a GRC tool (ServiceNow GRC / Archer / ManageEngine) to centralize risk & evidence.
• Deploy PAM, integrate SIEM with cloud tenants, implement DLP for sensitive data.

Phase 5 — Internal Audit & Management Review

Internal Audit Approach

• Use ISO 19011 guidance; audit plan covering processes & controls mapped to Annex A.
• Auditor independence: internal audit team reports to Audit Committee.
• Evidence sampling: configuration, logs, training records, policy sign-offs.

Outputs

• Internal Audit Report with findings (Major/Minor NCs)
• Corrective Action & Preventive Action (CAPA) plan
• Management Review Minutes — top risks, resource needs, continuous improvement items

Phase 6 — Certification Audit & Continuous Improvement

Certification Steps

1. Select accredited certification body
2. Stage-1: Documentation review & readiness confirmation
3. Stage-2: On-site/Remote audit and evidence verification
4. Address non-conformities and obtain certificate

Continuous Improvement (PDCA)

Plan (objectives & targets) → Do (implement controls) → Check (monitoring & audit) → Act (correct & improve).

Performance Metrics (KPI / KRI)

• % Controls Implemented: Target 100%
• % Non-conformities Closed: Target >95%
• MTTR (security incidents): Target <24 hrs
• User Awareness Score: Target >90%
• Number of Critical Incidents per year: Target 0

Expected Outcomes & Business Benefits

• ISO 27001:2022 certification and improved customer confidence
• Reduced residual risk exposure (example: target 40% reduction year-on-year)
• Centralized GRC platform and automated evidence collection
• Clear accountability & documented security processes

Closing Note

Reflection: माहितीचे संरक्षण हा फक्त तांत्रिक उपक्रम नाही — तो एक सांस्कृतिक परिवर्तन आहे. ISMS आणि GRC चा उद्देश फक्त प्रमाणपत्र मिळवणे नाही; म्हणजे व्यवसाय सुरक्षित ठेवणे, ग्राहकांचा विश्वास जिंकणे आणि सतत सुधारणा करण्याची प्रक्रिया स्थापन करणे हा आहे.
Quote: “Building a secure enterprise is not a one-time achievement — it’s a cultural transformation driven by governance, awareness, and accountability.”
