Zero standing privileges vs credential vaulting in modern PAM

At a glance

What this is: NHI Mgmt Group's analysis, drawing on Teleport's blog post: Credential vaulting can control privileged secrets but does not remove standing privilege, while zero standing privileges relies on ephemeral, identity-bound access.

Why it matters: IAM and PAM teams need to distinguish risk reduction from privilege elimination, because vault-based controls can still leave reusable credentials, persistent access paths, and audit blind spots in place.

By the numbers:

• Valid privileged accounts were responsible for 41% of successful attacks, according to CISA’s FY23 Risk & Vulnerability Assessments report cited by Teleport.

Context

Zero standing privileges is an access model where no account remains usable unless a task is actually under way. In practice, that means privileged access should be issued for the session or job, then disappear when the work ends, rather than surviving as a reusable secret.

The governance problem is that many PAM programmes still depend on credential vaults to store, rotate, and distribute privileged secrets. That can improve control over passwords and keys, but it does not automatically remove the standing access window that zero standing privileges is meant to close.

For IAM and NHI programmes, the distinction matters because vaulting can manage credentials while leaving the underlying entitlement model intact. The article frames this as a control gap between protecting secrets and eliminating persistent privilege.

Key questions

Q: What breaks when privileged access is controlled only by a vault?

A: A vault controls where the credential sits, but not what happens after the credential is released. Once the password is checked out or exposed, attackers can use memory theft, malware, insider misuse, or session abuse to extend impact. Privileged access therefore needs inline enforcement, not only protected storage.

Q: Why do password vaults create more risk than PAM in organisations with sensitive infrastructure?

A: Password vaults reduce storage friction, but they do not provide the fine grained authorization, discovery, or oversight needed for privileged access. That gap matters when passwords protect infrastructure, shared accounts, or service accounts. Without central control, teams can lose track of where credentials live, who uses them, and whether access remains appropriate.

Q: How do teams know whether zero standing privilege is actually working?

A: Teams should look for evidence that privileged access is time-bound, fully revoked, and impossible to reuse outside the approved session. If old secrets remain valid, break-glass accounts stay active, or administrators can operate without a fresh grant, ZSP is only partially implemented.

Q: What is the difference between vaulting privileged credentials and using just-in-time access?

A: Vaulting protects privileged credentials by storing them securely and rotating them on a schedule or after use. Just-in-time access goes further by granting elevation only for a specific task and time window, then revoking it automatically. Vaulting reduces exposure, while just-in-time access removes standing privilege and narrows the attack window.

Technical breakdown

Why credential vaults preserve standing privilege

A vault changes where a secret is stored and how it is rotated, but it does not erase the fact that the secret exists. If a password, SSH key, or API token can be checked out and reused, the account remains a standing privilege between rotations. That is a different model from ephemeral access, where the credential has no durable value outside the task window. Vaults also introduce another privileged dependency: the service accounts and policy paths that keep the vault operating. That creates a second layer of persistent access that must itself be governed.

Practical implication: treat vaulting as secret containment, not as proof that standing privilege has been removed.

How just-in-time access changes the control model

Just-in-time access issues credentials only when a request is approved or a task starts, and then binds them to identity, role, and time. In a zero standing privilege design, access is not checked out from a durable store and held until later reuse. Instead, privilege is created for the immediate session and expires automatically when the session ends. That changes the governance model from rotation-centric maintenance to issuance-centric control. It also reduces the reliance on human discipline to remember revocation steps or manage checkout workflows.

Practical implication: move privileged access decisions to issuance time, with short-lived certificates or tokens tied to the requesting identity.

Why vaults become brittle in modern cloud and AI environments

As infrastructure spreads across cloud, pipelines, and AI workloads, manual credential handling becomes harder to keep consistent. Every missed rotation, delayed revocation, or mis-scoped policy extends exposure. Vaults can store more secrets, but they cannot remove the existence of those secrets or the operational dependency on checking them out. That makes scaling difficult when service accounts, APIs, and AI agents all need machine-readable access. The more identities and systems rely on stored credentials, the more the control becomes an inventory problem rather than a privilege-elimination model.

Practical implication: examine whether your current PAM design is scaling secret inventory instead of reducing access persistence.

Threat narrative

Attacker objective: The attacker’s objective is to exploit reusable privileged access rather than a single short-lived session, expanding reach across systems and preserving covert reuse opportunities.

1. Entry occurs through a privileged secret that can be retrieved from a vault and reused outside the immediate task window.
2. Escalation happens when that reusable credential remains valid long enough to be copied, replayed, or used for broader administrative access.
3. Impact follows when standing privilege persists across systems, creating a larger attack surface and weakening accountability over who actually used the access.

NHI Mgmt Group analysis

Vaulting controls secrets, not standing privilege: A credential vault can reduce exposure, but it still assumes a durable secret exists and can be checked out, reused, or rotated. That assumption is sufficient for legacy PAM, but it does not satisfy zero standing privilege, which requires that privilege not persist between tasks. The practical conclusion is that vaulting and ZSP solve related but different governance problems.

Zero standing privilege is an issuance model, not a storage model: The central design choice is whether privileged access is created only when needed or merely hidden until someone retrieves it. Identity-bound, short-lived credentials change the governance unit from the secret to the session. That is why ZSP aligns better with modern cloud, workload, and agent workflows than vault-centric control.

Standing privilege becomes more visible as non-human identities multiply: Service accounts, APIs, and AI agents do not reduce the problem by existing in a vault. They often increase the number of privileged paths that can be stored, inherited, and reused. The result is a larger entitlement surface that must be governed at issuance, not just at rest.

Vault concentration creates its own privilege boundary: When one system stores many privileged secrets, the vault itself becomes a high-value administrative choke point. Misconfiguration or overbroad vault policy can turn a control into an amplifier of privilege. The field should treat vault governance as a separate risk layer, not as evidence that privileged access has been fully modernised.

Ephemeral credential trust debt: This article exposes a specific control debt in many PAM programmes: they have modernised secret handling without eliminating the trust assumptions that standing access requires. Zero standing privilege closes that debt by making privilege temporary by design, not by cleanup after the fact.

From our research library:

• 91% of organisations say at least half of their privileged access is always-on, and only 1% have fully implemented just-in-time privileged access, according to a CyberArk study.

What this signals

Ephemeral credential trust debt: Many PAM programmes have improved secret handling without changing the underlying privilege model, so the access path can still outlive the task it was supposed to support. That creates a governance gap between secure storage and actual privilege elimination.

As cloud and AI workloads multiply, the operational test is no longer whether credentials are vaulted, but whether access can exist without a reusable secret at all. Teams that cannot answer that question are still running a standing-privilege model, just with better packaging.

For practitioners

• Reclassify vaults as secret stores, not ZSP controls Document which privileged paths still depend on check-out, reuse, or delayed revocation. If a credential can survive beyond the task, the model still contains standing privilege.
• Replace checkout-based admin access with JIT issuance Issue short-lived credentials tied to the requesting identity and task, then let them expire automatically. This removes the operational dependency on manual return, rotation, or later revocation.
• Map privileged service accounts behind the vault Inventory the accounts, policies, and automation paths that make the vault work. Those back-end identities often carry the real standing privilege risk, even when the secret itself is rotated.
• Audit vault policy as part of PAM governance Review who can retrieve, approve, or administer secrets, not just who owns the credential. A tightly stored secret with broad retrieval rights still leaves the access model effectively standing.

Key takeaways

• Credential vaulting can reduce exposure, but it does not by itself remove standing privilege from PAM.
• The article’s core distinction is between protecting reusable secrets and issuing access only for the duration of a task.
• Teams that want zero standing privilege need identity-bound, short-lived access, not a better place to store long-lived credentials.

Key terms

• Zero Standing Privileges (ZSP): A security posture where no identity, human or non-human, holds persistent access rights. Access is provisioned dynamically on demand and automatically revoked after use. ZSP is the gold standard for NHI access control.
• Credential Vaulting: Credential vaulting stores privileged secrets in a controlled system rather than distributing them to users or embedding them in workflows. The security value comes from reducing direct exposure, supporting revocation, and creating a single governance point for high-risk credentials.
• Just-in-Time Access Request: Just-in-Time Access Request is a pattern that grants access only when it is needed and only for the duration required. It reduces standing privilege by making access temporary, policy driven, and task scoped. This approach is especially useful for contractors, sensitive systems, and short-lived operational work.
• Standing Privilege: Standing privilege is access that remains active even when no immediate task requires it. For NHI programmes, it is a common failure mode because long-lived credentials and persistent roles create unnecessary exposure. Reducing standing privilege usually means tighter expiry, on-demand access, and clearer review of who or what still needs access.
