Start with the financial reporting risk
Section 404 underpins management reporting on internal control over financial reporting. The SEC's interpretations explain how the requirements apply. SOX is not a prescribed list of data-detection patterns, and a DLP policy does not itself establish that financial reporting controls are effective.
Map the reporting work product
Select a significant reporting process and trace the data from source export to final review. Identify the approved workbook or record, its owner, authorised editors and the location used for evidence. Distinguish an uncontrolled working copy from the record that supports a reporting decision.
Review where email attachments, local downloads or shared folders can bypass the intended approval. Protecting confidentiality and controlling changes address different risks; neither should be assumed to prove the other.
Test changes and transfers separately
For a representative close task, test whether an unapproved transfer is detected and whether a legitimate reviewer can obtain the required information. Separately test the process for editing, approving and reconciling the reporting record. Retain the policy version, reviewer identity and resulting decision.
Build evidence around an explicit control objective
An event log is useful only when the control owner can explain what it demonstrates. Link the sample to a financial reporting risk, document the expected response and record how exceptions are resolved. SEC guidance should inform the assessment boundary; broad claims that a product makes an organisation SOX compliant should be avoided.

Practical checklist
- Identify the relevant reporting process and control owner.
- Separate access, change-control and confidentiality objectives.
- Test approved reporting work as well as unauthorised transfers.
- Keep reviewed evidence linked to the financial reporting risk.
Applying this with TRIAS
Use TRIAS classification and DLP evaluation to test handling of selected financial reporting records. Integrate relevant event evidence into the organisation's control process. Accounting judgments, reconciliations and management's ICFR assessment remain separate responsibilities.
