Alex uses fragmentation and decoy scans : But the firewall logs spikes

Alex, ethical hacker. 1. Firewall Evasion – The First Glance Alex scans the external perimeter. A classic nmap -sS triggers port 80 (HTTP) and 443 (HTTPS) only. Firewall is stateful—drops unsolicited SYN packets to other ports. But the firewall logs spikes

A simple curl request for /cgi-bin/test.cgi?cmd=ls triggers a signature (known attack pattern). But the firewall logs spikes
