Database Firewall
DBShield is a Database Firewall written in Go that has protection for MySQL/MariaDB, Oracle and PostgreSQL databases. It works in a proxy fashion inspecting traffic and dropping abnormal queries after a learning period to populate the internal database with regular queries.
For example, this is how web server normally interacts with database server:
By adding DBShield in front of database server we can protect it against abnormal queries. To detect abnormal queries we first run DBShield in learning mode. Learning mode lets any query pass but it records information about it (pattern, username, time and source) into the internal database.
After collecting enough patterns we can run DBShield in protect mode. Protect mode can distinguish abnormal query pattern, user and source and take action based on configurations.
