It should be tied in whenever the credential grants access beyond a single local application boundary. If a secret can reach infrastructure, data stores, or vendor systems, it needs ownership, recertification, and revocation controls similar to privileged access. Otherwise, the organisation is managing trust without accountability.
Why This Matters for Security Teams
secrets management becomes a privileged access problem the moment a credential can reach infrastructure, shared data stores, CI/CD, or vendor systems. At that point, the secret is no longer just an application setting. It is an access path that can outlive teams, workloads, and even employees unless it is tied to ownership, review, and revocation. That is why NHI Management Group treats lifecycle control as the missing control plane for secrets that operate beyond a single boundary.
Current guidance aligns with the OWASP Non-Human Identity Top 10 and NIST’s broader access governance model in the NIST Cybersecurity Framework 2.0: if a secret can be used to authenticate, authorize, or automate action, then it needs the same accountability as privileged access. NHIMG research shows how often this fails in practice. The The 2025 State of NHIs and Secrets in Cybersecurity report found that 91% of former employee tokens remain active after offboarding, a clear sign that lifecycle discipline is lagging behind exposure.
In practice, many security teams encounter secret abuse only after a leaked token has already been used to reach production systems, rather than through intentional lifecycle review.
How It Works in Practice
The operational rule is simple: if a secret can be used outside a local app boundary, it should be managed like privileged access. That means assigning an owner, defining an approval path, setting a review cadence, and revoking the secret when the workload, integration, or user changes. The key distinction is between local configuration secrets, which may stay within a tightly controlled runtime, and cross-boundary secrets that can reach databases, cloud APIs, CI/CD systems, or third-party services. Those latter secrets need PAM-style controls because they create real blast radius.
A practical implementation usually combines vaulting, provisioning, and lifecycle enforcement. Teams should distinguish between static secrets and dynamic, short-lived credentials, then prefer the latter where the architecture supports it. NHIMG’s Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and Ultimate Guide to NHIs — Static vs Dynamic Secrets are useful references for this distinction. In the most mature models, the secret is issued just in time, scoped to the task, monitored during use, and revoked when the workflow ends.
- Classify every secret by blast radius, not by storage location alone.
- Require an owner and business purpose before a secret is approved.
- Align rotation, recertification, and deprovisioning with PAM and joiner-mover-leaver processes.
- Prefer ephemeral credentials for automation, pipelines, and service-to-service access.
- Detect duplicate or orphaned secrets, then remove them from all locations, not just the vault.
The Guide to the Secret Sprawl Challenge shows why central storage alone is not enough: a secret that is copied into tickets, repositories, or chat tools still needs lifecycle control. These controls tend to break down in fast-moving CI/CD environments because secrets are created and reused faster than ownership and revocation can be manually tracked.
Common Variations and Edge Cases
Tighter lifecycle control often increases operational overhead, requiring organisations to balance faster delivery against stronger accountability. That tradeoff is real, especially where legacy applications, vendor integrations, or long-running batch jobs cannot easily use short-lived credentials. Current guidance suggests treating those exceptions as temporary risk acceptances, not as a reason to abandon lifecycle governance altogether.
There is no universal standard for every environment yet, but the pattern is consistent. If a secret is embedded in code, shared across teams, reused by multiple apps, or handed to a third party, it should be governed like privileged access. If it is purely local and cannot escape the runtime, lighter controls may be acceptable, though ownership and rotation still matter. NHIMG’s Top 10 NHI Issues and NHI Lifecycle Management Guide are relevant because secret sprawl often starts with one exception that later becomes the default.
The strongest edge-case test is whether the secret can survive personnel change, environment change, or vendor change without immediate detection. If the answer is yes, PAM and lifecycle controls are not optional. If the answer is no, the secret may still need basic vaulting, but it is less likely to require full privileged-access treatment. The real judgment call is not where the secret is stored; it is how far the secret can travel and how quickly it can be removed when that path changes.
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 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Secrets need rotation, ownership, and revocation when they cross trust boundaries. |
| NIST CSF 2.0 | PR.AC-4 | Lifecycle control supports least privilege and access review for secrets. |
| CSA MAESTRO | A2 | Automation secrets in agentic or workflow systems need scoped, revocable access. |
Classify cross-boundary secrets as privileged access and enforce lifecycle review, rotation, and revocation.
