Start with inventory. Organisations cannot govern access, review risk, or enforce policy until they know which assets exist and which identities can reach them. A practical first step is a central management view of assets, accounts, and access paths, then enrich it with read-only discovery methods so teams can see the environment without disrupting operations.
Why This Matters for Security Teams
Visibility is the prerequisite for control. If teams cannot see which assets exist, who owns them, and which non-human identities can reach them, every later decision about access review, segmentation, logging, or policy enforcement rests on guesswork. That is especially true for secrets, service accounts, API keys, and other NHI pathways that accumulate outside normal joiner-mover-leaver processes. The problem is not just incomplete inventory, but inconsistent definitions across cloud, SaaS, code repositories, and infrastructure.
Current guidance suggests starting with a single management view that unifies assets, accounts, and access paths, then layering read-only discovery to reduce operational risk. NHI research from Ultimate Guide to NHIs — Why NHI Security Matters Now and the Top 10 NHI Issues both point to the same operational reality: organisations often discover hidden exposure only after they begin mapping dependencies. In practice, many security teams encounter overexposed identities only after a breach review or cloud migration has already expanded the attack surface.
How It Works in Practice
Effective visibility programs do not start with enforcement. They begin with read-only discovery, normalisation, and ownership mapping so the security team can build an authoritative picture without breaking live workloads. For assets, that means pulling from cloud control planes, CMDBs, SaaS admin logs, infrastructure-as-code, and endpoint telemetry. For identities, it means collecting service accounts, workload identities, OAuth grants, API tokens, certificates, and privileged automation accounts, then tying each one back to a workload, application, or business owner.
A practical approach is to build three layers:
Asset inventory: systems, services, data stores, and external-facing endpoints.
Identity inventory: humans, NHIs, machine accounts, app registrations, and secrets tied to each identity.
Access-path inventory: direct logins, delegated access, role assignments, API scopes, trust relationships, and service-to-service routes.
That structure helps teams move from “what exists” to “what can reach what.” It also prepares the ground for policy decisions that depend on context, such as whether an identity should ever hold standing access or whether it should be brokered just in time. For broader NHI operating patterns, the NHI Lifecycle Management Guide is useful because lifecycle control only works after discovery is reliable.
For implementation discipline, align the discovery model with NIST SP 800-53 Rev 5 Security and Privacy Controls and use CISA cyber threat advisories to prioritise externally exposed services and identity paths first. These controls tend to break down when shadow IT, unmanaged SaaS, and ephemeral cloud workloads create identities faster than discovery jobs can normalise them.
Common Variations and Edge Cases
Tighter inventory controls often increase operational overhead, requiring organisations to balance completeness against the cost of constant reconciliation. That tradeoff becomes more visible in hybrid estates, acquisitions, and developer-led environments where owners rotate faster than platforms can update metadata. Best practice is evolving, but there is no universal standard for how much freshness is enough across every environment.
One common edge case is third-party access through OAuth apps and delegated tokens. Even strong CMDB coverage can miss these links because the relationship lives in an authorisation grant rather than an obvious account record. Another is ephemeral infrastructure, where containers, serverless functions, and short-lived build agents exist long enough to perform work but not long enough to fit traditional asset management cycles. In these cases, discovery should be event-driven as well as scheduled.
The security team should also expect gaps when owners are ambiguous. If an NHI or asset cannot be assigned to a system owner, it should be treated as a governance defect, not merely a data-quality issue. That is why the 52 NHI Breaches Analysis and the JetBrains GitHub plugin token exposure matter: they show how hidden credentials and weak visibility turn into real incident paths. The pragmatic answer is to accept partial coverage at first, but require every new blind spot to be documented, owned, and scheduled for remediation.
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, NIST AI RMF and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Inventory and discovery are foundational to spotting hidden NHIs and exposed secrets. |
| NIST CSF 2.0 | ID.AM-1 | Asset management requires a current, authoritative inventory to support all later controls. |
| NIST AI RMF | GOV-1 | AI governance depends on knowing which systems and identities are in scope before controls are applied. |
| NIST Zero Trust (SP 800-207) | RA-2 | Zero trust decisions need visibility into identities, devices, and resources before access is granted. |
Build a complete NHI and secret inventory before enforcing rotation, review, or privilege limits.
