SOX audit controls: what IAM teams need to tighten now

TL;DR: SOX audits test access controls, segregation of duties, change management, and account activity to confirm financial reporting remains accurate and defensible, according to Zluri. For identity teams, the real issue is not the checklist itself but whether access reviews, evidence collection, and control ownership are reliable enough to survive audit scrutiny.

Questions worth separating out

Q: How should security teams support SOX audits with identity governance?

A: Security teams should tie SOX controls to concrete identity evidence: who had access, who approved it, when it was reviewed, and whether conflicts were removed.

Q: Why do access reviews matter so much in SOX compliance?

A: Access reviews matter because SOX auditors need proof that entitlements match job function and that sensitive financial systems are not overexposed.

Q: What breaks when segregation of duties is weak in financial systems?

A: When segregation of duties is weak, one identity can influence the full transaction lifecycle, from creation to approval to reporting.

Practitioner guidance

• Map financial reporting paths to identity owners Identify every identity that can create, approve, reconcile, or modify financial reporting data, then assign a named owner for each control boundary and exception path.
• Separate approval and execution rights Review roles so no user or service account can both initiate and validate the same material financial workflow, especially where journal entries or access requests are involved.
• Automate access certification evidence Use an access review workflow that records reviewer decisions, timestamps, and remediation outcomes in one system of record so auditors can trace control execution without manual reconstruction.
