The business or technical owner who can prove the identity’s purpose, scope, and retirement path should be accountable. Shared or anonymous ownership is a control failure because it prevents timely revocation, review, and rollback. Without accountable ownership, machine identities become permanent blind spots in incident response.
Why This Matters for Security Teams
After a compromise, service account and tokens are not just artifacts to clean up. They are active paths to data, infrastructure, and downstream automation, so accountability determines whether the response is fast or fragmented. Current guidance from NIST SP 800-53 Rev. 5 emphasizes assigning responsibility for access control and system integrity, while NHIMG research on the Guide to the Secret Sprawl Challenge shows how quickly unmanaged credentials spread across tools and teams.
The practical issue is ownership drift. Security may detect the compromise, but only the business or technical owner can prove why the identity exists, where it should be used, and when it should be retired. That distinction matters because incident response needs more than containment: it needs rollback, replacement, and confirmation that the identity is no longer valid anywhere else. In NHIMG’s analysis of 52 NHI Breaches Analysis, repeat failure patterns consistently trace back to unclear ownership and weak lifecycle control.
In practice, many security teams encounter token abuse only after lateral movement has already started, rather than through intentional lifecycle control.
How It Works in Practice
Accountability should be assigned to the owner who can demonstrate three things: the identity’s purpose, its approved scope, and its retirement path. That owner is usually the application owner, service owner, or platform team lead, not the SOC, because the SOC can coordinate revocation but cannot defend the business need for the identity. Security and IAM teams should enforce the control plane, but ownership must stay with the people who can approve replacement, attest to legitimate use, and confirm that dependent systems will not break when the token is revoked.
Operationally, this means every service account or token should have an explicit owner, a business justification, a defined system of record, and an incident contact who can authorize emergency action. During compromise handling, the owner should support:
- Immediate revocation or quarantine of the credential
- Replacement with a short-lived credential or a freshly issued token
- Review of where the secret was used, copied, or embedded
- Validation that no orphaned integrations still depend on it
NHIMG research on Guide to the Secret Sprawl Challenge and the vendor data in The 2025 State of NHIs and Secrets in Cybersecurity both reinforce the same lesson: duplicated and overused identities make revocation harder because one compromised token may have multiple hidden dependencies. NIST guidance on access control in NIST SP 800-53 Rev 5 Security and Privacy Controls supports this operational model by tying accountability to control ownership, not just technical access.
These controls tend to break down in environments with shared automation accounts, undocumented pipeline secrets, or cross-team tokens that were created for convenience and never registered in a system of record.
Common Variations and Edge Cases
Tighter accountability often increases operational overhead, requiring organisations to balance fast incident response against accurate ownership and dependency tracking. That tradeoff becomes visible in shared platform environments, where one token supports multiple apps, or in legacy estates where service accounts were created before lifecycle governance existed.
There is no universal standard for this yet, but current guidance suggests that shared ownership should still resolve to one accountable owner, with others listed as contributors or approvers. If no single owner can explain the identity’s purpose and retirement path, the credential should be treated as a control failure rather than a governance exception. For internet-facing integrations, the risk is amplified by token sprawl and hidden copies, as seen in NHIMG reporting on the Salesloft OAuth token breach and broader compromise patterns in the The 52 NHI breaches Report.
The exception is emergency containment, where the SOC may act first and assign accountability afterward. Even then, the owner must be identified quickly so replacement can happen without creating a new outage. Where service accounts are embedded in CI/CD, SaaS connectors, or agentic workflows, accountability should extend to the team that can rotate the credential and prove downstream impact before re-enabling it.
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 |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Ownerless service accounts are a classic non-human identity governance failure. |
| NIST CSF 2.0 | PR.AC-1 | Access is only manageable when identities have clear accountable ownership. |
| NIST AI RMF | AI governance needs accountable ownership for autonomous identities and actions. |
Assign accountable owners for machine identities and document who approves, monitors, and retires them.
