Stage 01 — Network Reconnaissance

Automated Nmap scanning discovers open ports and running services across target hosts. Includes a custom port-to-service override map to correct systematic Nmap misidentifications (e.g. MySQL on 3306 misclassified as Nagios NSCA), recovering missed CVE detections.
