Yes. Application secrets behave like machine identities because they authenticate systems, not people, and they need lifecycle governance just like any other non-human identity. IAM teams should apply inventory, access scope review, rotation, and offboarding discipline to those secrets instead of leaving them in ad hoc application ownership.
Why application secrets should be governed like machine identities
Application secrets are not just configuration values. When a secret lets a workload authenticate, call an API, or reach a backend, it is functionally acting as a non-human identity credential. That means the IAM question is not “who owns the file”, but “what does this secret authorize, for how long, and how is it revoked when the application changes?”
The practical consequence is that secret handling needs the same discipline you would apply to other machine-facing access paths. If the secret is still valid, it can still be abused, even when the application code is unchanged or the team believes it is “just a secret”.
What changes when a secret is treated as an identity artifact?
Three things change immediately. First, the secret becomes part of an inventory problem: teams must know where it exists, what system it authenticates, and which environments depend on it. Second, access scope matters: a broad secret is a broad privilege grant, even if it is stored outside an IAM platform. Third, lifecycle rules apply: issuance, rotation, expiry, revocation, and offboarding must be managed deliberately.
This is why secret management and machine identity management converge. If a secret is embedded in a service, pipeline, or integration, then the real control question is whether the credential can be rotated, reduced in scope, and removed without breaking production. API Key Management Guide and NHI Lifecycle Management Guide both reinforce that lifecycle discipline matters as much as storage.
For teams modernising this model, the goal is often to move from long-lived shared secrets toward narrower, short-lived credentials or workload identity patterns. That is a governance decision as much as a technical one, because it reduces the chance that one embedded value silently becomes a standing production access path.
Where IAM teams usually get this wrong
The common failure is to leave application secrets under ad hoc application ownership while IAM focuses only on human accounts. That creates blind spots around inventory, review, and revocation, especially when secrets are duplicated across environments or copied into code, CI/CD variables, or deployment tooling. Guide to the Secret Sprawl Challenge is a useful reminder that hidden distribution and weak discovery are often the real risk, not storage alone.
A second failure is to treat rotation as optional because the application is “stable”. Stability does not reduce exposure if the secret is static. A leaked credential can remain useful for weeks or months unless the owning team has a clear rotation and cutover process. The same logic applies to offboarding: if the integration is retired, the credential must be revoked, not just forgotten.
For machine-facing access, broad patterns such as OWASP Non-Human Identity Top 10 and SPIFFE workload identity specification help frame the same issue in different ways: credentials must be visible, scoped, and replaceable, or they become permanent access paths.
What IAM teams should operationalise
Start by classifying application secrets by function, not by storage location. A secret that authenticates a production service, a CI/CD job, or an API client should be tracked as an identity-bearing object with an owner, purpose, scope, and expiry expectation. That classification then drives review cadence, rotation strategy, and exception handling.
IAM teams should also insist on a handoff model that makes secret ownership explicit. Application teams may operate the workload, but IAM should define the control standard for issuance, review, rotation evidence, and retirement. Where secrets are used for service-to-service access, the same logic should apply to privilege minimisation and environment separation, not just to password policies.
For platform teams, the best control pattern is usually one that reduces the number of static secrets in the first place. Secrets Management Guide and Guide to SPIFFE and SPIRE support that shift by showing how secret centralisation, ephemeral credentials, and workload identity can improve control without making operations brittle.
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 addresses the attack surface, NIST SP 800-53 Rev 5, CIS Controls v8 and CSA Cloud Controls Matrix set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-02 — Secret Leakage | Application secrets can expose machine access when leaked or copied. |
| NHI-01 — Improper Offboarding | Retiring apps requires revoking their secrets and access paths. | |
| NHI-07 — Long-Lived Secrets | Static app secrets create standing access that outlives need. | |
| Recommendation — Treat application secrets as identity-bearing credentials and reduce leakage exposure. Revoke application secrets when systems are decommissioned or replaced. Replace long-lived application secrets with short-lived, rotated credentials. | ||
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Covers lifecycle, rotation, and revocation of authenticators used by systems. |
| IA-9 — Service Identification and Authentication | Application secrets often authenticate services and workloads to each other. | |
| AC-6 — Least Privilege | Secret scope should be limited to the minimum access required. | |
| Recommendation — Manage application secrets as authenticators with rotation and revocation controls. Use service authentication controls to govern application-to-application secrets. Scope each application secret to the least privilege needed for its function. | ||
| ISO/IEC 27001:2022 | A.5.16 — Identity management | Application secrets need ownership and lifecycle governance as identity artifacts. |
| A.5.17 — Authentication information | Secrets are authentication material and require protection and management. | |
| Recommendation — Define ownership and lifecycle rules for application secrets. Protect and manage application secrets as authentication information. | ||
| CIS Controls v8 | CIS-5 — Account Management | Secret-backed application access needs inventory, review, and deprovisioning discipline. |
| Recommendation — Inventory and retire application secrets with the same discipline as accounts. | ||
| CSA Cloud Controls Matrix | IAM — Identity & Access Management | Cloud application secrets are part of identity and access governance. |
| Recommendation — Govern application secrets through cloud identity and access controls. | ||
Practitioner Guidance
What to verify: Every application secret should have a named owner, a documented purpose, a scope boundary, and a rotation or expiry path. If any of those four are missing, IAM does not actually have governance over that credential.
Decision rule: If the secret can authenticate to production or reach sensitive data, treat it as a privileged identity artifact and prioritise rotation, scope reduction, and offboarding before debating whether the application team “really owns” it.
What good looks like: Secrets are inventoried, mapped to the systems they authorize, rotated on a known schedule or by event, and removed when the integration is retired. The observable sign of maturity is not perfect secrecy, it is recoverable control.
Practitioner takeaway: The right standard is not whether a value is called a secret, but whether it grants machine access. If it does, IAM should govern it with the same lifecycle discipline used for any other non-human identity credential.
