 - Detects SQL injection attacks using two methods:
   - **Signature-based detection**: Detects SQL injection attacks by matching incoming queries against a list of known malicious queries using a trained deep learning model with Tensorflow and Keras
   - **Syntax-based detection**: Detects SQL injection attacks by parsing incoming queries and checking for suspicious syntax using `libinjection`
-- Prevents SQL injection attacks by blocking malicious queries from reaching the database server, and returning an error to the client instead

 - Logs an audit trail for detections containing the query and the prediction score
 - Sigma rule for detection in SIEM systems
 - Prometheus metrics for quantifying detections
