GreenSQL is an Open Source database firewall used to protect databases from SQL injection attacks. GreenSQL works as a proxy for SQL commands and has built in support for MySQL & PostgreSQL . The logic is based on evaluation of SQL commands using a risk scoring matrix as well as blocking known db administrative commands (DROP, CREATE, etc). GreenSQL is distributed under the GPL license. You can download it here.

GreenSQL works as a reverse proxy for MySQL connections. This means, that instead of connecting TO THE MySQL server, your applications will connect to THE GreenSQL server. GreenSQL will analyze SQL queries and then, if they're safe, will forward them to the back-end MySQL server.

The following picture describes the whole process.
