Teams should align review scope to the business-critical systems AD protects, then document who approved each entitlement, who recertified it, and when logs were retained. The goal is not just compliance activity, but defensible evidence that access stayed tied to role, risk, and business need.
How AD review scope should map to compliance evidence
AD access reviews should start from the business-critical systems and privileged pathways AD actually protects, then translate that scope into reviewable entitlements, groups, and admin paths. For SOX, HIPAA, and iso 27001, the useful question is not “did we run a review?” but “can we prove the access was appropriate for the system’s risk and the reviewer’s authority?”
That means the review package should show the entitlement owner, the approver, the recertification date, and the evidence trail that supports the decision. For teams building a control map, NHIMG’s Identity Security Regulatory Map is a useful way to align identity controls to SOX, HIPAA, and ISO 27001 without treating those frameworks as interchangeable.
When AD is the authoritative source for workforce access, the review should also include the dependent controls that make the certification defensible, such as role design, privileged group membership, and delegated administration. That is why teams often anchor the review process in the broader Active Directory and Entra ID Hardening Guide rather than treating review as a standalone audit task.
What to include in the review evidence
A strong review packet should separate access that is merely present from access that is actually justified. In practice, that means documenting whether an entitlement is tied to a defined role, whether it is a privileged exception, whether it is shared, and whether the business owner accepted the residual risk if it stayed in place.
For SOX, the key evidence is whether access that could affect financial reporting was reviewed by someone who can judge segregation and change risk. For HIPAA, the key evidence is whether access to systems handling protected health information was limited to job need and whether exceptions were approved and time bound. For ISO 27001, the evidence should show that access control, authentication, and logging are operating as planned, not just written down in policy. The ISO standard itself is a strong reference point for that control discipline, especially ISO/IEC 27001:2022 Information Security Management and its companion ISO/IEC 27002:2022 Information Security Controls.
Where teams need practical guidance on reviewing administrative access and containment boundaries, NHIMG’s Segregation of Duties (SoD) Guide helps connect review outcomes to toxic combinations, compensating controls, and privileged exceptions that should not be left to informal judgment.
How to make reviews defensible over time
Defensibility depends on consistency more than volume. A recurring AD review should produce the same classes of evidence every cycle, even if the specific entitlements change, so auditors can compare one review period to the next and see a stable method rather than ad hoc cleanup. The review should also retain enough context to explain why a previously approved entitlement later became invalid.
Teams should think in terms of ownership and lifecycle, not just certification. If an entitlement has no clear owner, or if the owner cannot explain why the access still exists, the control is already weakening. That is why lifecycle discipline matters in AD reviews, and why NHIMG’s NHI Lifecycle Management Guide is a relevant companion even for workforce-facing review programs, because it reinforces the importance of provisioning, review, and offboarding discipline across identity types.
For organisations that want a broader program view, the Identity Security Programme Guide is useful because it frames reviews as part of governance, RACI, and roadmap ownership rather than a one-off compliance activity. That perspective is especially important when AD supports multiple business units with different control expectations.
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 and CSA Cloud Controls Matrix set the technical controls, while ISO/IEC 27001:2022 and SOC 2 (AICPA) define the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| ISO/IEC 27001:2022 | A.5.15 — Access Control | AD review scope and approvals directly support access control governance for regulated systems. |
| A.8.2 — Privileged access rights | AD reviews must cover privileged memberships and administrative exceptions that affect regulated risk. | |
| A.8.15 — Logging | The question explicitly requires retained logs as defensible evidence of review and approval activity. | |
| Recommendation — Define review scope around business-critical access and retain approved evidence for each entitlement. Recertify privileged AD access separately and revoke exceptions without current business justification. Retain review logs that prove who approved, who recertified, and when the decision was made. | ||
| NIST SP 800-53 Rev 5 | AC-2 — Account Management | AD entitlement reviews are fundamentally account and membership management for regulated access. |
| AC-6 — Least Privilege | SOX, HIPAA, and ISO 27001 all depend on access being limited to business need and role. | |
| AU-9 — Protection of Audit Information | The page's evidence requirement depends on retaining review records with integrity and traceability. | |
| Recommendation — Review AD accounts and group memberships on a defined cadence and remove unjustified access. Right-size AD access so each account has only the permissions its role requires. Protect review evidence so certifications and approvals remain trustworthy during audit. | ||
| CSA Cloud Controls Matrix | IAM — Identity and Access Management | AD review governance is an IAM control problem across entitlement ownership and certification. |
| Recommendation — Map AD review outputs to identity ownership, approval, and recertification requirements. | ||
| SOC 2 (AICPA) | CC6.1 — Logical Access Security Software, Infrastructure, and Architectures | The question is about access reviews and evidence for controlled access to systems. |
| CC7.2 — Monitor System Components for Anomalies | AD reviews benefit from retaining logs and signals that reveal unusual access or review gaps. | |
| Recommendation — Use periodic access reviews to confirm regulated access remains authorised and documented. Monitor AD access changes and investigate review exceptions or unexplained entitlement drift. | ||
Practitioner Guidance
What to prioritise: Start with privileged groups, financial-reporting paths, clinical or patient-data systems, and any AD-linked access that can materially affect regulated business processes. Reviews that begin with low-risk access often create audit noise without reducing exposure.
What to verify: Each reviewed entitlement should have a named owner, a reason for access, a recertification decision, and a retention path for the evidence. If any one of those elements is missing, the review may have happened, but it is not yet audit-grade.
Common mistake: Teams sometimes certify group membership without checking whether the group still maps to the role that justified it. That shortcut is risky because role drift is exactly how old access survives into the next audit cycle.
Practitioner takeaway: The strongest AD review program is one that can explain why access exists, who accepted it, and how long that decision remains valid, because compliance evidence is only persuasive when it is tied to actual access governance.
