TL;DR: The article explains how identity proofing, authentication and authorisation fit together, and why access should only follow successful verification, with stronger factors such as MFA reducing fraud risk, according to Imprivata. The governance lesson is that identity assurance fails when each step is treated as interchangeable instead of a distinct control point.

Questions worth separating out
Q: How should security teams separate authentication from authorisation in IAM policy?
A: Security teams should treat authentication as proof that an identity is credible and authorisation as the policy decision that follows.
Q: Why do strong login controls still leave access risk unresolved?
A: Strong login controls only reduce the chance of unauthorised entry.
Q: What breaks when service accounts are governed like human logins?
A: What breaks is the lifecycle model.
Practitioner guidance
- Separate proofing, authentication and authorisation in policy Document each stage as a distinct control with its own owner, evidence source and review cadence.
- Tighten privilege after identity is verified Review roles, group memberships and PAM assignments immediately after authentication design changes.
- Apply the same lifecycle discipline to machine identities Track service accounts, API tokens and certificates through enrolment, usage, rotation and revocation.

Identity proofing, authentication and authorisation are separate control problems, not synonyms. Organisations that collapse them into one governance bucket usually overestimate assurance at the front door and under-control privilege at the back end. The discipline is to treat identity evidence, login verification and entitlement assignment as distinct decisions with different owners and audit trails. Practitioners should preserve that separation in both IAM design and access review.
A few things that frame the scale:
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time, according to the Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: How can organisations tell whether zero trust is working for machine identities?
A: They should look for continuous re-evaluation of identity, context and access scope, not just a hardened sign-in event. If tokens, certificates or service accounts stay valid without review, zero trust is only partially implemented. Effective programmes show short-lived access, clear revocation paths and audit evidence for every entitlement.
