What Is SOX (Sarbanes-Oxley) Compliance?

SOX (Sarbanes-Oxley) Compliance Explained

Sarbanes-Oxley passed in 2002 following the Enron and WorldCom collapses, and it changed corporate accountability from a governance aspiration into personal legal exposure. Section 302 requires the chief executive and chief financial officer to personally certify each quarterly and annual report, including that they have evaluated the effectiveness of disclosure controls. Section 906 attaches criminal penalties to knowingly false certifications. The practical effect is that executives now demand demonstrable evidence rather than assurances from their finance and IT organizations.

Section 404 is where the operational work lives. Section 404(a) requires management to assess and report on the effectiveness of internal control over financial reporting annually. Section 404(b) requires the external auditor to attest to that assessment, though smaller reporting companies and non-accelerated filers have been exempted from the auditor attestation, and emerging growth companies receive a temporary exemption. Most companies structure their control environment using the COSO Internal Control - Integrated Framework, which organizes controls across control environment, risk assessment, control activities, information and communication, and monitoring.

For ERP teams, IT general controls are the direct obligation. ITGCs cover four domains: access to programs and data, program change management, program development, and computer operations. In practice this means documented user provisioning and periodic access recertification, approved and tested changes with separation between developer and production deployer, controlled implementation of new functionality, and monitored backup, batch job, and interface processing. If ITGCs are deemed ineffective, auditors cannot rely on any automated control or system-generated report, which cascades into extensive manual testing.

Segregation of duties is the control most often deficient in mid-market ERP environments. The canonical conflicts are the same user creating a vendor and paying an invoice, entering a purchase order and receiving against it, or posting a journal entry and approving it. Small finance teams create these conflicts naturally, and ERP security models built around convenience concentrate them further. Where segregation is genuinely impossible, compensating controls - independent review of exception reports, dual approval thresholds, monitored audit logs - must be documented and tested rather than assumed.

A material weakness is the outcome to avoid. It is a deficiency, or combination of deficiencies, creating a reasonable possibility that a material misstatement would not be prevented or detected in time. Disclosure of a material weakness typically damages share price, raises the cost of capital, and triggers remediation programs consuming significant finance and IT capacity. Section 802 separately makes destruction or alteration of records with intent to obstruct a federal investigation a criminal offense, which is why records retention and audit trail configuration are treated as SOX matters, not just archival policy.
