The 2022 revision places more emphasis on cloud security, threat intelligence, supply chain risk, and resilience, all of which depend on identity controls. That means IAM and NHI teams need to show how access governance, third-party dependencies, and recovery processes are controlled inside the ISMS, not outside it.
Why ISO/IEC 27001:2022 changes the IAM and NHI conversation
ISO/IEC 27001:2022 matters because it pulls identity governance into the information security management system rather than treating IAM as a separate technical programme. For IAM and NHI teams, that means access control, privileged access, supplier risk, logging, and recovery all need evidence inside the ISMS. The standard’s emphasis on resilience and operational control aligns closely with the realities documented in Ultimate Guide to NHIs, where secrets exposure and excessive privilege remain common failure modes.
The practical consequence is simple: auditors increasingly expect the organisation to show how identities are governed across cloud workloads, integrations, and third parties, not only how employees authenticate. That lines up with NIST Cybersecurity Framework 2.0, which treats identity as a core control plane for protection and resilience. In practice, many security teams encounter NHI weaknesses only after a secret leak or supplier incident has already exposed gaps in the ISMS, rather than through intentional governance design.
How it works in practice for IAM, privileged access, and NHI governance
In a mature ISO/IEC 27001:2022 programme, IAM and NHI controls should be mapped to scope, risk treatment, control ownership, and evidence collection. The objective is not to prove that access exists, but that access is granted, reviewed, revoked, and monitored according to documented policy. For NHIs, that includes service accounts, API keys, workload identities, certificates, and automation credentials.
A practical implementation usually includes:
- an asset and identity inventory that includes human and non-human identities;
- formal access approval and review workflows for privileged and service access;
- short-lived secrets or tokens where the environment supports them;
- logging and alerting on credential issuance, misuse, and revocation;
- supplier controls for third-party accounts, integrations, and delegated access.
Current guidance suggests treating NHI governance as part of access control and supplier assurance, not as an add-on vault project. NHIMG’s Top 10 NHI Issues highlights how excessive privilege, poor rotation, and weak visibility are recurring patterns that belong in risk registers and internal audit evidence. For broader context, the NIST Cybersecurity Framework 2.0 reinforces identity governance as a cross-functional control, while ISO/IEC 27001:2022 makes that governance measurable through the ISMS. These controls tend to break down when machine identities are created automatically in CI/CD or cloud orchestration without an owner, because the identity lifecycle outruns the review process.
Where the standard gets tricky: cloud, suppliers, and evidence quality
Tighter control over identity and access often increases operational overhead, requiring organisations to balance assurance against delivery speed. That tradeoff is especially visible for NHI programmes, where short-lived workloads, delegated cloud permissions, and external integrations can change faster than manual governance processes.
Best practice is evolving on how much evidence is enough for non-human identity controls, and there is no universal standard for this yet. Some organisations rely on periodic access reviews, while others move toward continuous assurance with policy-as-code and automated attestation. The latter is stronger, but it also requires better tooling, clearer ownership, and more disciplined change management.
This is where ISO/IEC 27001:2022 can expose weak spots. If the ISMS only tracks named people, it misses service accounts, API keys, and cross-tenant trust relationships. If supplier risk reviews do not include identity issuance and revocation paths, third-party access stays live long after it should have been removed. NHIMG’s 2024 Non-Human Identity Security Report shows how often organisations still struggle with dynamic ephemeral credentials and consistent access across hybrid environments, which is exactly the kind of operational gap that can undermine audit confidence. The hardest cases are multi-cloud estates with automated provisioning, because identity evidence becomes fragmented across platforms and no single team owns the full lifecycle.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AA | Identity governance and access control are central to the question. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Credential rotation and secret hygiene are core NHI audit concerns. |
| NIST AI RMF | AI-assisted automation often depends on identities and access governance. |
Document NHI credential lifecycle controls and prove rotation, revocation, and monitoring are enforced.
