Understanding the Overhead of Database Monitoring and Auditing

Pages 12 Pages

This whitepaper demystifies the performance overhead of database auditing by comparing agent-based Database Activity Monitoring (DAM) with native database auditing. While both methods introduce some overhead, modern systems minimize this impact through efficient buffering and data handling. The key difference lies in control: native auditing allows granular, precise policies (e.g., by user, object, or privilege), enabling better risk management and lower overhead. DAM tools, limited to connection-based auditing, often require broad data capture and yield higher overhead. For modern security needs—including UEBA and AI-driven detection—native auditing offers superior scalability, performance, and actionable insight.
