Why do unmanaged grants create more risk than approved access changes?

Why This Matters for Security Teams

Unmanaged grants are not just another access review gap. They create a second, shadow authorization path that bypasses approval records, ownership, and revocation discipline. That makes it difficult to prove why access exists, whether it is still needed, and who is accountable when it is abused. Current guidance from the NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 treats this as a governance failure, not a paperwork issue.

In NHI environments, the risk is amplified because unmanaged grants often attach to service accounts, API keys, cloud roles, and CI/CD permissions that remain active long after the original business need has changed. NHI Management Group’s Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, which shows how quickly unchecked access becomes the norm rather than the exception. In practice, many security teams encounter abuse only after an incident, rather than through intentional access design.

How It Works in Practice

Approved access changes follow a lifecycle: request, review, approval, implementation, logging, and later removal. That chain creates an evidence trail that supports least privilege, auditability, and faster containment. Unmanaged grants skip one or more of those steps. The access may be technically valid, but it lacks operational legitimacy because no one can readily explain who approved it, what task it was meant to support, or when it should expire.

For NHI governance, the practical difference is decisive. Approved changes can be tied to role design, ticketing, and periodic recertification. Unmanaged grants tend to accumulate in direct cloud permissions, repository exceptions, secret stores, and ad hoc integrations. They also resist normal cleanup because no owner is clearly responsible for revocation. NHIMG research on the NHI lifecycle process and the Top 10 NHI Issues shows why visibility and offboarding are recurring weak points.

• Approved changes create ownership, scope, and expiry conditions.
• Unmanaged grants usually have none of those guardrails.
• Approved changes can be reviewed against policy-as-code and access baselines.
• Unmanaged grants often survive because no workflow exists to challenge them.

That is why modern controls increasingly emphasise identity governance, JIT provisioning, and automated revocation rather than static trust. These controls tend to break down when access is granted directly in production cloud consoles without ticket linkage because the record of intent is missing.

Common Variations and Edge Cases

Tighter access governance often increases operational overhead, so organisations must balance speed against the risk of unchecked privilege sprawl. That tradeoff is real in high-change environments such as incident response, platform engineering, and ephemeral CI/CD pipelines, where teams may grant temporary access to keep delivery moving. Current guidance suggests that the answer is not to block all exceptions, but to make exceptions time-bound, owner-assigned, and automatically revisited.

There is no universal standard for this yet, but best practice is evolving toward short-lived approvals, just-in-time elevation, and regular recertification for exceptions that cannot be fully removed. The regulatory and audit perspective in NHIMG research reinforces that auditors care less about whether access was once necessary and more about whether the organisation can show continuing control. That distinction matters when an unmanaged grant was created to solve a real business problem but was never reclassified into a governed access path.

Approved exceptions can also become unmanaged over time if owners leave, tickets expire without cleanup, or toolchains duplicate permissions across environments. The practical test is simple: if the organisation cannot explain the grant in one sentence and prove its expiry path, it should be treated as a risk, not as a harmless shortcut.
