Audit scope and identity risk: what IAM teams miss

TL;DR: Audit scope defines what auditors can examine, but narrow scoping can miss overprivileged access, weak evidence trails, and third-party exposure across the identity surface, according to Zluri. For IAM and NHI teams, the real risk is treating scope as a paperwork exercise instead of a control boundary.

NHIMG editorial — based on content published by Zluri: Access Management Audit Scope & Its Impact: A Detailed Guide

By the numbers:

• Only 5.7% of organisations have full visibility into their service accounts.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.

Questions worth separating out

Q: How should security teams define audit scope for non-human identities?

A: Start with the systems that hold sensitive data, then include every identity that can reach them, including service accounts, API keys, tokens, certificates, and third-party connectors.

Q: Why do narrow audit scopes create blind spots in IAM programmes?

A: Narrow scopes often exclude the identities that carry the most operational privilege, especially shared accounts and machine credentials.

Q: How can teams tell whether an audit scope is too limited?

A: If the evidence set stops at people, department charts, or one application layer, the scope is probably too limited.

Practitioner guidance

• Expand audit scope to cover non-human identities Include service accounts, API keys, tokens, certificates, and vendor access whenever they touch regulated data, production systems, or admin functions.
• Tie scope to entitlement pathways Map each in-scope application to the identities, roles, and third-party connectors that can reach it so auditors can follow the access path end to end.
• Require evidence for ownership and offboarding For every non-human identity in scope, maintain an owner, a purpose, and a revocation path so dormant access cannot survive the audit cycle.
