Real-Time Anomaly Detection with Python By Victor • HNG DevSecOps Project Case Study In the modern web landscape, static rate limiting is often a blunt instrument. While it can stop basic brute-force attacks, it struggles with sophisticated, low-and-slow DDoS attacks or sudden legitimate traffic spikes. For my latest HNG DevSecOps project, I built a dynamic Anomaly Detection & DDoS Engine that learns from your traffic patterns and defends your AWS infrastructure in real-time.
