What methodology should be included in the DRL when the audited entity is focused on transaction monitoring?

When an audited entity is focused on transaction monitoring, it's crucial to include a transaction-tuning methodology in the Data Review Log (DRL). This methodology is specifically designed to enhance the effectiveness of the transaction monitoring systems by adjusting the parameters used to identify suspicious transactions. Transaction tuning involves analyzing historical alert data, assessing the quality of alerts generated by the system, and calibrating the detection algorithms accordingly.

The rationale behind this choice lies in the importance of adapting the transaction monitoring tools to reduce false positives while ensuring that genuine suspicious activities are effectively detected. It typically requires collaboration between compliance teams and data analysts to iteratively improve the threshold levels and parameters used in the monitoring system, ultimately increasing efficiency and effectiveness at detecting potential risks.

In contrast, while risk assessment methodology, compliance fulfillment methodology, and performance evaluation methodology are all relevant to overall compliance and auditing practices, they do not specifically address the nuances and requirements of optimizing transaction monitoring systems. These methodologies serve broader purposes and may not provide the focused approach necessary for refining transaction monitoring processes.
