Workday and SOX §404: What IT Auditors Check and How to Pass
Workday processes payroll, manages headcount, and controls compensation data — all material to financial reporting. SOX §404 requires management to assess the effectiveness of the controls around that data. Here are the 12 ITGCs auditors test in every Workday review, the evidence each one requires, and exactly where to find it.
1. Why Workday is in SOX scope
Workday processes payroll (directly material to financial reporting), manages headcount and org structure (material to workforce cost reporting), and controls access to compensation and benefits data (material to benefits expense reporting). The tenant is in the §404 perimeter, full stop.
2. The four ITGC domains auditors test
- Logical Access Controls — who can access what; provisioning/deprovisioning; service-account scoping.
- Change Management — Preview testing before production promotion; documented change control; approval records.
- Computer Operations — integration monitoring; alert subscribers; integration failure response process.
- Program Development — peer review of new integration/configuration before go-live.
3. The 12 specific controls
- C1 — User access provisioning evidence.
- C2 — User access deprovisioning (#1 finding when termination date doesn't match Workday account deactivation date).
- C3 — Privileged access review.
- C4 — ISU access scope review.
- C5 — ISU UI session restriction ('Do Not Allow UI Sessions' must be checked).
- C6 — Integration monitoring (alert subscriber list and schedule run history).
- C7 — Configuration change management (Preview promotion records and change tickets).
- C8 — Segregation of duties (no single user in both Compensation Partner view and Payroll Partner modify).
- C9 — Password policy and ISU credential rotation records.
- C10 — Business process security (approval chain definitions for material transactions).
- C11 — Calculated field validation (no production fields in error state).
- C12 — SOC 2 review (Workday's SOC 1 Type II and complementary user entity controls).
4. Producing an auditor-ready evidence package
Use Workday's built-in reports for each control: 'View Security Groups,' 'Compare Security Permissions,' 'View Integration System User,' 'Integration Audit,' 'Business Process View,' 'All Calculated Fields.' Export each as evidence and tag with the control ID.
5. How Yoetz.ai covers C1–C11 in a single 2-hour scan
Every finding is automatically mapped to its SOX control ID, GDPR article, ISO 27001 Annex A control, and PCI-DSS requirement. The export is a formatted evidence package ready for SOX submission.
Frequently asked questions
Does Yoetz.ai produce control-by-control evidence?
Yes — every finding maps to a specific SOX ITGC and exports as auditor-ready evidence.
Will the auditor accept automated evidence?
Yes, when paired with the source Workday report exports the scan references. Big 4 firms increasingly accept automated coverage as a basis for testing.
Can we use this for SOX 404(b) external auditor attestation?
Yes for evidence — the external auditor will still perform their own control testing on a sample.
How does this handle SoD across Workday Financials?
The scan extends to Financial Management security groups using the same connector.
How often should we run it?
Quarterly, plus once per Workday R1 and R2.
What does the auditor see?
A formatted PDF/CSV evidence package with one row per control, the test procedure, the Workday source, and the result.
