They should do both, but identity-centric PAM comes first when privilege is already dynamic and distributed across NHIs. Static role cleanup helps, yet it does not solve the deeper problem of how access is issued, observed, and retired. If privilege changes faster than roles can be reviewed, the governance model is already behind.
Why identity-centric PAM comes before static role cleanup
Static roles are a useful hygiene exercise, but they describe a permission model after the fact. Identity-centric PAM starts with who or what can actually exercise privilege now, which is the better control point when access is granted through vaults, JIT elevation, service accounts, and delegated workflows. That is why privilege management should lead when privilege is fluid, not neatly role-bound.
When organisations rely on role cleanup alone, they often reduce noise without reducing exposure. A role can look tidy while the underlying access path remains broad, long-lived, or reusable. Identity-centric PAM is designed to constrain the actual privilege event, not just tidy the label attached to it.
For distributed privilege, the question is less “does the role still exist?” and more “can this identity still do anything powerful, when, for how long, and with what trace?” That lens matters for NHIs, cloud admin paths, emergency access, and third-party support accounts because the operational privilege path is often separate from the formal role catalogue. Privileged Access Management Guide frames PAM around vaulting, JIT access, session control, and zero standing privilege.
What static role cleanup fixes, and what it does not
Role cleanup is still valuable because it removes stale entitlements, simplifies review, and improves governance confidence. It is strongest where access is stable, human-owned, and clearly mapped to job function. In those environments, a cleaner role model reduces overassignment and makes certification more meaningful.
It does not, however, solve runtime privilege drift. If a service account, token, device, or automation path can still reach critical systems, the role model may be clean while the real exposure remains. That is why identity governance and PAM should be treated as complementary, not interchangeable.
There is also a sequencing issue. When privilege changes faster than role review cycles, cleanup becomes a lagging control. Organisations should use role rationalisation to reduce the baseline, then use PAM to govern the privileged actions that persist outside the role model. Service Account Security Guide is a useful example of why discovery, governance, and rotation matter even when the role structure appears orderly.
How to decide where to invest first
Prioritise identity-centric PAM first when one or more of these are true: privilege is dynamic, privileged actions are shared across many systems, access is granted through non-human identities, or you cannot confidently answer who used elevated access last. In those cases, reducing role clutter alone will not materially reduce risk.
Start with the identities that can cause the most damage, not the roles with the longest names. That usually means admin accounts, service accounts, break-glass paths, and third-party support access. Once those are controlled with JIT, session oversight, and rotation, role cleanup becomes a sharper, more measurable governance exercise. Just-in-Time Access and Zero Standing Privilege Guide shows why time-bound elevation is often the right first control when privilege is temporary by design.
Risk and Threat Considerations
Static role models can create a false sense of control when attackers, insiders, or third-party operators can still reach privileged functions through standing access, stale credentials, or delegated workflows. The exposure increases when privileged paths are hard to enumerate or when one identity can act across multiple systems without a tight session boundary.
Failure mechanism: The organisation cleans up catalogue roles but leaves real-world privilege issuance, session use, and credential retirement largely unchanged, so excessive access survives behind a tidier governance surface.
Impact: Attackers gain more durable paths to escalation, lateral movement, and destructive action, while defenders lose the ability to prove that privileged use was bounded and observable.
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 sets the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-05 — Overprivileged NHI | Privilege that outgrows roles is a core NHI/PAM exposure. |
| NHI-07 — Long-Lived Secrets | Role cleanup does not retire long-lived secrets that preserve privilege. | |
| Recommendation — Reduce standing privilege and right-size non-human access before relying on role cleanup. Rotate and shorten secret lifetime so cleanup is not defeated by persistent credentials. | ||
| NIST SP 800-53 Rev 5 | AC-6 — Least Privilege | The question is about controlling excess privilege, not just organizing roles. |
| IA-5 — Authenticator Management | PAM depends on managing credentials, rotation, and retirement. | |
| Recommendation — Enforce least privilege on actual access paths, not only on role definitions. Manage credential lifecycle so elevated access is issued and revoked cleanly. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | The issue is whether access is governed effectively across identities and privilege paths. |
| Recommendation — Apply access control rules to the real privilege path, not only the role catalog. | ||
Practitioner Guidance
What to prioritise: Treat standing privileged access, reusable secrets, and unmanaged emergency paths as the first reduction targets. If those exist, role rationalisation should support PAM, not delay it.
What to verify: Confirm that elevated access is time-bound, session-visible, and retired at the end of use. If you cannot produce evidence of issuance and revocation, the access model is still too static for the privilege pattern you actually have.
Decision rule: If the same identity can still obtain powerful access faster than your role review cycle can remove it, the right control priority is PAM, then cleanup of the role model beneath it.
Practitioner takeaway: Clean roles reduce governance friction, but identity-centric PAM reduces actual blast radius, so the first priority is to control how privilege is granted and used, then simplify the roles that remain.
