This document discusses fraud detection and prevention through transactional analysis. It outlines the challenges of fraud management, including large data volumes, complex systems, and evolving fraud schemes. Traditional fraud detection methods like internal controls and audits are reactive and often detect fraud long after the fact. The document advocates for continuous transaction monitoring using data analytics software. This allows comparing data across systems, testing transactions against fraud indicators, and detecting fraud earlier to prevent greater losses. While powerful, challenges include the effort to extract and compare data from multiple systems and developing flexible analytics.
