TL;DR: SOX compliance depends on controlling who and what can access financial systems, because access reviews, segregation of duties, logging, and timely offboarding are the practical controls that keep reporting defensible, according to Zluri. The underlying governance problem is that access creep and weak review cycles can turn compliance into a paperwork exercise rather than an operating control.

Key questions
Q: What breaks when SOX access controls depend on periodic reviews only?
A: Periodic reviews create a gap between when access changes and when the change is actually challenged.
Q: Why do weak segregation of duties controls create financial reporting risk?
A: Because one identity can end up creating, approving, and reconciling the same transaction path.
Q: How can organisations tell whether SOX access governance is actually working?
A: Look for consistent review outcomes, clear ownership, and evidence that can be reconciled across all in-scope systems without manual cleanup.
Practitioner guidance
- Define SOX-scoped access owners Assign named business owners for every financial reporting application, database, and privileged role so access reviews have a clear approver and exception path.
- Convert annual recertification into lifecycle checks Trigger reviews when employees join, change roles, or leave, and remove any entitlement that no longer maps to current reporting responsibilities.
- Encode segregation of duties in the access matrix Block role combinations that let one identity create, approve, and reconcile the same financial activity, and test those combinations before each release.
Bottom line: SOX compliance fails when financial-system access is broader or longer-lived than the business role that justified it.

SOX exposes an identity governance problem, not just a compliance checklist. The article is really about whether financial reporting access is bounded by role, lifecycle, and evidence. When access reviews are weak, SOX becomes retrospective documentation instead of active control. The practitioner conclusion is that financial reporting assurance depends on operational IAM discipline.
A question worth separating out:
A: Both. Access reviews are an IAM activity, but in a SOX context they are also a control validation step that protects reporting integrity. Treating them as separate creates blind spots, because the same entitlement decisions can determine whether a key control is operating as intended.
