Use Suricata as An Intrusion Detection System on AWS

This is Part 3 of a security engineering series covering Suricata IDS setup on a Debian EC2 instance in AWS. It teaches writing custom detection rules for SQL injection, port scanning, C2 beaconing, and DNS tunneling, along with iterative rule tuning, false positive resolution, and traffic analysis using tcpdump. The post also connects local Suricata rules to AWS Network Firewall and includes practice exercises.
