Treat that as an operating-model problem, not a tooling problem. Rework discovery, lifecycle controls, and approval paths so privileged access is granted only for defined work and removed as soon as the task ends. If persistent access remains normal, the deployment has not changed the security posture enough.
Why This Matters for Security Teams
PAM can reduce risk only when privileged access is genuinely temporary. If standing access remains after deployment, the organisation still has persistent pathways for misuse, lateral movement, and credential theft. That gap is especially dangerous for NHIs because secrets, tokens, and service accounts do not behave like human users. Current guidance from the OWASP Non-Human Identity Top 10 and NHIMG’s Ultimate Guide to NHIs both point to the same issue: access control fails when identity lifecycle and privilege lifecycle are not managed together.
The real problem is often organisational. Teams buy PAM, but they do not change how access is discovered, approved, issued, or revoked. That means accounts remain exempted for convenience, break-glass paths become permanent, and service owners keep broad entitlements because no one owns the cleanup. In practice, many security teams encounter standing privilege only after a secrets leak, an audit exception, or an incident has already exposed the gap.
How It Works in Practice
The effective response is to treat standing access as an exception to eliminate, not a normal state to tolerate. Security teams should first map every privileged path: human admin accounts, service accounts, API keys, automation tokens, and any shared credentials that can reach sensitive systems. From there, they should align OWASP guidance with operational controls that force access to be time-bound, task-bound, and owner-approved.
At a practical level, that usually means:
- Replacing permanent entitlements with just-in-time access for named work items.
- Issuing short-lived credentials with automatic expiry and revocation.
- Using workload identity for machines and agents so access is asserted cryptographically, not inherited from a long-lived secret.
- Reviewing approvals for intent, scope, and duration rather than simple role membership.
- Logging every elevation request and correlating it with the task that justified it.
NHIMG’s analysis of secret exposure shows how fast this matters in the real world. In LLMjacking: How Attackers Hijack AI Using Compromised NHIs, publicly exposed AWS credentials were attempted within an average of 17 minutes. That is why standing access is not just a policy weakness, it is an exploit window. The control objective is to make privilege ephemeral, observable, and revocable before an attacker can reuse it.
These controls tend to break down in legacy environments where shared admin accounts, hard-coded secrets, or batch jobs depend on always-on access and no service owner has authority to refactor them.
Common Variations and Edge Cases
Tighter PAM often increases operational overhead, requiring organisations to balance stronger control against incident-response speed and application uptime. That tradeoff is real, especially where production support, emergency recovery, or third-party maintenance depends on rapid access. Best practice is evolving, and there is no universal standard for this yet, but current guidance suggests that exceptions should still be time-boxed, monitored, and reviewed after use rather than left in place indefinitely.
The hardest cases are hybrid estates and automation-heavy platforms. Legacy systems may not support granular scoping, while cloud and CI/CD pipelines may blur the line between human and machine privilege. In those environments, a standing account can hide behind an automation label even when it is effectively human-managed. NHIMG’s 52 NHI Breaches Analysis shows how often this pattern appears once identities are allowed to accumulate access faster than they are reviewed.
For teams moving toward maturity, the practical question is not whether PAM exists, but whether the operating model removes default persistence. If an account can still authenticate tomorrow without a fresh business need, the privilege model has not changed enough.
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, OWASP Agentic AI Top 10 and CSA MAESTRO address the attack and risk surface, while NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Standing access often means credentials are not rotated or revoked on time. |
| OWASP Agentic AI Top 10 | A-04 | Autonomous workflows need task-scoped privilege instead of persistent access. |
| CSA MAESTRO | ID | Workload and agent identity must be tied to least privilege for each execution. |
| NIST AI RMF | AI governance requires lifecycle controls for autonomous or semi-autonomous privilege use. |
Eliminate permanent privileged credentials and enforce time-bound issuance with automated revocation.
