Exact question
How should we respond when a customer asks for evidence of access reviews?
Independent expert review has not yet been recorded. This page provides operational guidance, not professional advice.
Provide a completed review record for the relevant systems and population, showing who reviewed access, when they reviewed it, what decisions they made, and how removals or exceptions were followed through. A policy or current user list can support the response, but neither proves that a review occurred.
What the requester is trying to establish
They usually want confidence that access remains appropriate after roles, projects and personnel change, and that inappropriate access is identified and resolved.
Who this normally applies to
It applies when systems, roles or user populations relevant to the customer relationship are periodically or eventfully reviewed. Frequency and evidence expectations depend on the requester, contract, framework and risk.
Questions to answer before responding
- Which applications, environments, roles and users are in scope?
- What review period and completion date does the requester expect?
- Who was authorized to decide whether access remained appropriate?
- Were privileged, service, dormant and external accounts included?
- How were revocations, changes and accepted exceptions tracked?
Likely internal owners
The system or business owner should decide appropriateness. IT can extract and change access. Security or operations can coordinate and test completeness.
Evidence commonly requested
| Item | What it contributes | Important limitation |
|---|---|---|
| Completed review record | Reviewer, population, decisions and date | Scope may exclude systems or account types |
| Source access export | Population reviewed | Snapshot alone is not a review |
| Change tickets or logs | Follow-through on removals | Must link to review decisions |
| Exception approval | Reason, owner and review date | Does not make the residual risk disappear |
What each evidence item proves
The combined package can show that a defined access population was presented to accountable reviewers and that their decisions were recorded and acted upon.
What it does not prove
It does not prove continuous appropriateness between review dates, correctness of every source record, or coverage beyond the stated scope.
Weak or insufficient responses
An access-control policy, an unannotated user export, a calendar invitation, or a statement that reviews happen “regularly” does not demonstrate a completed review.
Step-by-step completion process
- Clarify requested scope and acceptable redaction.
- Preserve the source population and extraction time.
- Confirm that accountable reviewers covered the full population.
- Record keep, change, remove and investigate decisions.
- Link corrective actions and verify their completion.
- Record approved exceptions separately.
- Package a redacted summary with provenance and limitations.
Example response structure
Describe the systems and population, review window, reviewer roles, decision categories, completion status, exceptions and attached evidence. Provide counts only when they can be reconciled to the underlying record.
Common mistakes
Do not conflate manager acknowledgement with a completed review, hide unfinished actions, omit service accounts without explanation, or send an unredacted access list unnecessarily.
Matters requiring professional judgment
An adviser may need to interpret framework-specific scope, regulated access rules, segregation-of-duties conflicts or disclosure constraints.
