List role assignments through the Microsoft Entra administrative interfaces or reporting views, then review both permanent and PIM-managed access. Check each assignment for owner, business justification, last use, and whether the role still matches the user’s duties. Prioritise global, security, and application administration roles, and remove assignments that are no longer needed.
How to build a complete Microsoft Entra role assignment review
Start by separating the inventory step from the judgement step. Microsoft Entra roles should be reviewed from both administrative views and access review reports, because permanent assignments and PIM-managed assignments behave differently even when they grant the same standing authority.
For a role review to be useful, each assignment needs context: who owns it, why it exists, when it was last used, and whether the current job function still justifies it. That is why reviews should focus first on the highest-impact roles, especially global, security, and application administration roles.
A good review is not just a count of assignments. It is a control check on whether standing privilege still matches business need, whether privileged access is being actively used, and whether temporary elevation is being handled through the intended approval path instead of becoming permanent by drift.
What to check in each Entra role assignment
Review every assignment for three practical questions: does the person still need the role, is the assignment correctly owned and documented, and is there evidence that the role is being used in line with its purpose? If an assignment exists only because nobody has revisited it, treat that as a review failure, not a neutral finding.
PIM-managed access deserves the same scrutiny as permanent access, but the review lens is slightly different. For eligible roles, check whether activation patterns look reasonable, whether activation justification is meaningful, and whether the role is still appropriate as an eligible entitlement. For active assignments, check whether the role should have remained temporary at all.
Role scope matters as much as role name. A reviewer should confirm whether the assignment is for the right tenant, environment, or administrative boundary, and whether the role’s reach is broader than the user’s current responsibility. This is especially important where broad admin roles can quietly accumulate operational power far beyond their original purpose. For deeper coverage of role assignments, scopes, and app-related administration patterns, see Azure RBAC and Service Principals Guide.
When the review reveals that privileged standing access is being retained simply for convenience, the right response is usually removal or conversion to just-in-time access, not a longer exception note. If the role is still needed, keep the assignment narrow and recorded; if not, remove it and verify that the business process still works without it.
How to prioritise and evidence the review
Prioritise the roles that can change tenant-wide security posture first, then move outward to departmental and application-specific administration. A review of global, security, and application administration roles should be treated as high value because a single stale assignment can affect multiple systems, not just one workload.
Use the review outcome to confirm both governance and technical hygiene. Good evidence includes an identified owner, a clear business justification, a recent usage signal, and a documented decision to retain, reduce, or remove the assignment. Where PIM is in use, the review should also show that activation controls and review cadence are part of the operating model, not just a one-time setup choice. Microsoft’s own Privileged Identity Management (PIM) Guide is the most direct reference for the eligible-versus-active distinction and the review workflow around privileged access.
If the assignment belongs to an application, service, or delegated admin model, confirm that the role is still aligned with the current architecture and that the owning team still understands the blast radius. This is where role review becomes a control over unnecessary privilege growth, not just an administrative tidy-up. Stale admin rights are often paired with broader identity hardening concerns, which is why Active Directory and Entra ID Hardening Guide is useful background when role review is part of a wider privileged-access programme.
Where a role is tied to an app registration or service principal, review whether that dependency still exists and whether the role is being preserved for an identity that no longer needs it. In practice, role review should surface these cases before they become hidden privilege paths, especially in environments where application administration is shared or poorly documented.
Risk and Threat Considerations
Role assignments become risky when they outlive the reason they were granted. Excessive or stale privileged access can turn a normal admin path into a standing compromise path, especially when the assignment is broad, rarely reviewed, or attached to an account that is no longer under active operational ownership.
Failure mechanism: Privilege accumulates because assignments are not revisited after job changes, project changes, or temporary elevation events, so the account retains authority that no longer matches the user’s duties.
Impact: The organisation increases the chance of unauthorized administrative action, lateral movement through privileged functions, and avoidable blast radius if the account is misused or compromised.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5 sets the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | AC-2 — Account Management | Role assignment review governs account entitlements and retention of standing privilege. |
| AC-6 — Least Privilege | Entra role reviews exist to minimize excessive administrative authority. | |
| AU-6 — Audit Record Review, Analysis, and Reporting | Last-use checks and review evidence depend on audit visibility into role activity. | |
| Recommendation — Review accounts and remove unnecessary role assignments promptly. Limit role assignments to the minimum access needed for the task. Use audit data to validate whether privileged roles are still being used. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Role assignment review is a core access-control governance activity. |
| A.5.18 — Access rights | The question is directly about reviewing and removing access rights. | |
| Recommendation — Define and enforce role review rules for privileged access. Periodically recertify and revoke access rights that are no longer justified. | ||
Practitioner Guidance
What to prioritise: Start with roles that can affect tenant-wide security or broad application control, then move to lower-impact administrative access. If a role has no recent use and no current owner can justify it, treat removal as the default outcome.
What to verify: Make sure the review distinguishes permanent assignments from PIM-managed access, because those should not be judged the same way. Verify that business justification, last use, and role fit are recorded well enough that another reviewer could repeat the decision without guesswork.
Common mistake: Approving a role because it is “normal” for the user’s team. Normality is not justification; the assignment still needs a current duty, a named owner, and a reason it must remain standing rather than eligible.
Practitioner takeaway: The most reliable Entra role review is one that removes standing privilege by default and keeps only the access that can still be defended as current, necessary, and actively governed.
