Isaca Exam CISA Topic 5 Question 70 Discussion

The best way to prevent fraudulent payments is to implement segregation of duties between the vendor setup and payment processing. Segregation of duties is an important control measure used to mitigate the risks associated with fraud and errors. By separating the processes of vendor setup and payment processing, it ensures that no single individual has control over both activities, and thereby reduces the risk of fraudulent payments. Additionally, other measures such as dual authorization and automated controls can be used to further reduce the risk.
