Database Firewall

Definitions

1. A security layer that inspects and controls database traffic or queries to block suspicious patterns, unauthorized statements, or policy violations. Database firewalls are used to reduce abuse even when the application or accounts are already trusted.

   In plain English: A protective filter that monitors and blocks dangerous database requests.

   Example: "The database firewall blocked ad hoc `UNION SELECT` queries from an application account that should never issue them."
