Este documento describe varias técnicas de escaneo de puertos TCP e IP, incluyendo conexión TCP, SYN, FIN, UDP, ACK, Null y Xmas. Explica cómo cada técnica identifica puertos abiertos, cerrados y silenciosos mediante el envío y recepción específica de paquetes. También discute las ventajas y desventajas de cada método en términos de velocidad, discreción y capacidad de detección.
