Techniques de scan de ports -sS(Scan TCP SYN) Le scan SYN est celui par défaut et le plus populaire pour de bonnes raisons. Il peut être exécuté rapidement et scanner des milliers de ports par seconde sur un réseau rapide lorsqu'il n'est pas entravé par des pare-feux. Le scan SYN est relativement discret et furtif, vu qu'il ne termine jamais les connexions TCP. Il marche également contre toute pile respectant TCP, au lieu de dépendre des particularités environnementales spécifiques comme les scans Fin/Null/Xmas, Maimon ou Idle le sont. Cette technique est souvent appelée le scan demi-ouvert (half-open scanning), car il n'établi pas pleinement la connexion TCP. -sT(Scan TCP connect()) Le scan TCP connect() est le type de scan par défaut quand le SYN n'est pas utilisable. Si le scan SYN est disponible, il vaut mieux l'utiliser. -sU(Scan UDP) Même si les services les plus connus d'Internet son basés sur le protocole TCP, les services UDP sont aussi largement utilisés. Le scan UDP est activé avec l'option-sU.
