Crosswalk Library/ISO 27001 ↔ NIST CSF
ELDR Institute · Governance Crosswalk

Map ISO/IEC 27001:2022 Annex A controls to NIST Cybersecurity Framework 2.0 functions and categories, enabling organizations that operate under both frameworks to create unified governance documentation architectures rather than maintaining parallel compliance programs.

Scope & Applicability

ISO/IEC 27001:2022 Annex A (93 controls across 4 themes) mapped to NIST CSF 2.0 (6 Functions: GOVERN, IDENTIFY, PROTECT, DETECT, RESPOND, RECOVER). Applicable to organizations pursuing ISO 27001 certification that also use NIST CSF as their primary security governance framework — common in financial services, healthcare, and government contracting.

Crosswalk Overview

Substantial structural overlap exists between the two frameworks, but they operate at different levels of abstraction. NIST CSF describes what security outcomes to achieve; ISO 27001 Annex A specifies how to achieve them. Organizations with a mature NIST CSF program have typically implemented the organizational behaviors that ISO 27001 Annex A controls require — but ISO 27001 certification requires documented evidence of implementation that NIST CSF does not mandate.

Areas of Overlap

ISO 27001 A.5 (Organizational Controls)NIST CSF GOVERN, IDENTIFY

ISO 27001 A.7 (Physical Controls)NIST CSF PROTECT
ISO 27001 A.8 (Technological Controls)NIST CSF PROTECT, DETECT, RESPOND
Key Differences
Certification vs. Framework
ISO 27001 produces a third-party certification issued by an accredited certification body. NIST CSF is a voluntary framework without certification. Organizations cannot claim 'NIST CSF certified.'
Mandatory Documentation
ISO 27001 mandates specific documented information: ISMS scope, policy, risk assessment methodology, Statement of Applicability, risk treatment plan. NIST CSF has no mandatory documentation requirements.
Risk Assessment Structure
ISO 27001 requires a defined, repeatable risk assessment process per Clause 6.1.2. NIST CSF includes risk assessment categories but imposes no specific methodology.
Statement of Applicability
ISO 27001 requires an SoA documenting all Annex A controls with inclusion/exclusion justification. NIST CSF has no equivalent artifact.
Management Review
ISO 27001 Clause 9.3 requires documented management review at planned intervals. NIST CSF has no equivalent mandatory review cadence.
