Databases Must Become Security Gatekeepers as AI Agents Go Live

The traditional assumption that the application layer handles all security breaks down when autonomous AI agents directly access production databases. Unlike human-written code, agent-generated queries are unpredictable, can run indefinitely, and may silently fail—requiring databases themselves to implement defensive measures like read-only connections, approval gates, and comprehensive audit logs. This marks a fundamental shift in database architecture: from trusting the caller to verifying every action at the database boundary.
