Identity and PAM governance should own the policy, but the system owner and service owner must validate operational impact. The point is to make the decision from evidence and then enforce it through the platform, not to leave routing choices to ad hoc project teams.
Why This Matters for Security Teams
The ownership question is really about control boundaries: who has the authority to change how a workload authenticates, who absorbs the operational risk, and who is accountable when standing access becomes the easiest path for attackers. NHI Management Group research shows that 97% of NHIs carry excessive privileges and 71% are not rotated on time, which makes “leave it to the project team” a weak answer in practice. Evidence-based ownership is what turns privilege reduction from a one-off cleanup into an enforceable control.
Security teams often get this wrong by treating JIT or secret removal as a technical toggle instead of a governance decision with production impact. Identity and PAM functions need to own the policy because they define the control standard, the exception process, and the evidence threshold. The system owner and service owner must still validate whether the workload can function with ephemeral access, short-lived tokens, or no stored secret at all. That split prevents both over-permissioning and unmanaged outages. The same pattern appears across the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the OWASP Non-Human Identity Top 10, both of which frame governance as a lifecycle problem rather than a ticket queue.
In practice, many security teams encounter standing privilege only after a breach, failed audit, or emergency rotation reveals that no one ever owned the decision to remove it.
How It Works in Practice
The cleanest operating model is a three-way decision path. Identity or PAM governance sets the rule for when an account must move from standing privilege to JIT access, workload identity, or secretless authentication. The system owner explains what the application or automation actually needs to do. The service owner validates dependency timing, break-glass requirements, and whether the workload can tolerate short-lived credentials, token exchange, or a secrets manager-backed flow.
That approval should be based on evidence, not preference. Useful evidence includes authentication logs, secret usage frequency, privilege escalation history, rotation failure rates, and whether the workload is machine-to-machine, interactive, or batch. For agents and autonomous systems, the question becomes even stricter: if access is needed only for a task, current guidance suggests issuing it just in time and revoking it automatically when the task completes. The Guide to the Secret Sprawl Challenge and NHI Lifecycle Management Guide both support that lifecycle-based view.
A practical workflow usually looks like this:
- Identity or PAM defines the default state as no standing privilege unless a documented exception exists.
- The system owner confirms the workload can use JIT, workload identity, or a short-lived secret.
- The service owner signs off on performance, reliability, and rollback impact.
- The platform enforces the decision through policy-as-code, rotation, vaulting, or ephemeral token issuance.
- Exceptions are time-bound and reviewed with the same evidence used to justify the change.
This approach aligns with the NIST Cybersecurity Framework 2.0 emphasis on governed risk decisions and with the NIST SP 800-53 Rev 5 Security and Privacy Controls expectation that access changes be authorized, monitored, and reviewable. These controls tend to break down when ownership is split across multiple product teams without a single policy authority, because exception drift makes standing privilege quietly reappear.
Common Variations and Edge Cases
Tighter privilege reduction often increases operational overhead, requiring organisations to balance security gain against release friction, outage risk, and support maturity. That tradeoff is real, especially for legacy integrations, vendor-managed services, and batch jobs that still depend on static secrets or broad service accounts.
There is no universal standard for every edge case. Some systems can move straight to JIT or secretless patterns; others need a transitional model with segmented access, shorter TTLs, and stronger monitoring before full removal of standing privilege. In high-availability environments, the service owner may require dual control, staged rollout, or a fallback account for recovery, but that fallback should be time-bound and explicitly approved by identity governance rather than left in place indefinitely.
For agentic workloads, the threshold should be even stricter because autonomous systems can chain tools, repeat actions, and expand their reach faster than a human operator would. The right ownership model still does not change: identity or PAM owns the policy, system and service owners validate feasibility, and the platform enforces the outcome. When that is missing, standing access often survives under the label of “temporary” long after the original exception has expired.

OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0, NIST SP 800-53 Rev 5 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 | Covers governance for non-human identity access and privilege boundaries. |
| NIST CSF 2.0 | PR.AC-4 | Access permissions and least privilege map directly to the ownership decision. |
| NIST SP 800-53 Rev 5 | AC-2 | Account management covers authorization, modification, and removal of access. |
| CSA MAESTRO | GOV-02 | Agent and workload governance requires explicit ownership for access decisions. |
