How i built a Real-Time Anomaly Detection Engine for Cloud Storage

As part of my HNG DevSecOps task, I built a real-time anomaly detection engine to protect a Nextcloud instance from unusual traffic spikes and potential DDoS attacks. The goal was simple: monitor incoming traffic in real time, detect suspicious behavior automatically, and respond immediately before the server becomes overwhelmed. Instead of relying only on static thresholds, I wanted the system to learn normal traffic behavior and react intelligently when something abnormal happens. This project
