Teams should connect asset utilisation, ownership, and renewal data to access decisions so that dormant software, devices, and cloud resources are challenged before they become control gaps. The useful metric is not total inventory alone, but whether every asset has a current owner, a purpose, and a defined retirement path.
Why This Matters for Security Teams
IT asset management metrics become identity governance signals when they answer a simple question: which assets still justify access, and which ones are quietly expanding the attack surface? Dormant software licenses, abandoned cloud subscriptions, stale device fleets, and unclear ownership all create access entitlements that outlive the business need that created them. That is exactly how access drift turns into NHI sprawl.
Current guidance aligns with the NIST Cybersecurity Framework 2.0 approach to asset visibility and access governance, but practitioners need more than inventory counts. NHI Management Group research in the Ultimate Guide to NHIs and the Top 10 NHI Issues shows that lifecycle failures, not isolated credential mistakes, are what leave machine identities overexposed. The useful metric is whether the asset still has a valid owner, purpose, and retirement path, because identity decisions should change as soon as the asset stops being actively used. In practice, many security teams discover this only after dormant assets have already retained access for months.
How It Works in Practice
Teams should treat ITAM data as an input to entitlement review, not as a separate operational report. The goal is to connect asset utilisation, business ownership, renewal dates, and retirement status to identity controls so that access can be reduced, challenged, or revoked when an asset no longer has a legitimate role. That applies to laptops and servers, but also to SaaS tenants, API-connected applications, CI/CD runners, service accounts, and cloud resources that still authenticate long after the underlying project has ended.
A practical workflow usually looks like this:
- Map each asset record to a named business owner and an accountable technical custodian.
- Flag assets with no recent utilisation, no renewal event, or no assigned retirement date.
- Join ITAM data to IAM, PAM, and secret inventory so dormant assets are matched with their live credentials and tokens.
- Use the review to trigger access recertification, credential rotation, or decommissioning.
- Track exceptions separately so temporary business need does not become permanent access.
This is where identity governance becomes measurable. A device that is inactive but still enrolled in MDM may not be a control failure, but an inactive cloud workload with standing access to production data usually is. The same logic applies to non-human identities documented in the 52 NHI Breaches Analysis: unmanaged lifecycle and unclear ownership are recurring drivers of exposure. For control design, CSF concepts map cleanly to asset management, access control, and continuous monitoring, while lifecycle-oriented NHI guidance supports practical deprovisioning and review cadence. These controls tend to break down when CMDB, procurement, IAM, and cloud inventory are not reconciled, because no single system can tell whether the asset is still supposed to exist.
Common Variations and Edge Cases
Tighter ITAM-to-identity linkage often increases operational overhead, requiring organisations to balance governance precision against the cost of reconciliation and exception handling. That tradeoff is real, especially in environments with high contractor churn, short-lived cloud environments, or frequent software renewals.
Best practice is evolving for three common edge cases. First, shared platforms can make ownership ambiguous, so current guidance suggests assigning an accountable service owner even when the technology is jointly used. Second, ephemeral cloud resources may disappear before a standard review cycle completes, which means event-driven checks matter more than quarterly audits. Third, procurement records can show an active licence while the associated identity has already been decommissioned, so teams should not assume licence renewal equals operational necessity.
For identity governance, the important distinction is between assets that are intentionally dormant and assets that are merely forgotten. In the latter case, stale access is often the hidden problem. NHI Management Group recommends using asset age, last-seen activity, renewal status, and owner confirmation together rather than relying on any single metric. That is the most defensible way to reduce unnecessary entitlements without creating friction for legitimate business use.
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 | ID.AM-1 | ITAM metrics start with knowing what assets exist and who owns them. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Ownership and lifecycle gaps are core NHI governance failures. |
| NIST AI RMF | Governance of autonomous or semi-autonomous systems depends on asset accountability. |
Tie each asset record to an owner and keep identity decisions synced to current asset inventory.
