Auditing Fraud Detection, Segregation of Duties, and Financial Transaction Controls

This eBook supplies a repeatable, evidence-led method to evaluate whether fraud-detection and segregation-of-duties (SoD) systems protect confidentiality, rest on trustworthy data, detect relevant schemes with measurable effectiveness, produce precise and actionable alerts, enforce appropriate duties separation, support reliable investigation and audit trails, and cover both physical/financial inventory and equity securities. It is written for practitioners who must distinguish risk hypotheses from confirmed fraud, control design from operating effectiveness, and anomalies from errors or intentional misstatements. No system eliminates fraud risk. Management override, collusion, incomplete labels, and data gaps remain permanent limitations. Readers must tailor every procedure to the entity’s jurisdiction, accounting framework (e.g., U.S. GAAP), auditing standards (PCAOB, IIA IPPF), industry regulations (FDA/DEA for pharmaceuticals; correctional finance and custody rules for prisons), system architecture, and written authorization. Local legal, privacy, cybersecurity, valuation, and securities advice is required before acting on findings that affect regulated data, market-sensitive information, or potential enforcement matters.

Fraud-detection systems and SoD controls are only as reliable as the data they consume, the rules or models they apply, the access rights they enforce, and the human processes that investigate alerts. In prison and pharmaceutical environments, the stakes are elevated: controlled substances, high-value medical inventory, public or restricted funds, patient or inmate data, and, for public or closely held entities, ownership records
