This technique is often referred to as half-open scanning, because you don´t open a full TCPĬonnection. It also allows clear, reliable differentiationīetween the open, closed, and filtered states.

Nmap´s FIN/NULL/Xmas, Maimon and idle scans do. It also worksĪgainst any compliant TCP stack rather than depending on idiosyncrasies of specific platforms as Scan is relatively unobtrusive and stealthy, since it never completes TCP connections. Scanning thousands of ports per second on a fast network not hampered by restrictive firewalls. SYN scan is the default and most popular scan option for good reasons.
