Les différents états d’un port lors d’un scan.
| State | Description |
|---|---|
| OPEN | A port that responds actively to an incoming connection. |
| CLOSED | A port that responds actively to a probe but there is no service running on the respective port. |
| FILTERED | A port that is actively protected by a firewall and prevents Nmap from determining the port status [open or closed]. |
| UNFILTERED | A port can be scanned, but Nmap cannot precisely determine if the port is open or closed. |
| OPEN FILTERED | A port that Nmap sees as open but cannot precisely determine the actual state of the port. |
| CLOSED FILTERED | A port that Nmap sees as closed but cannot precisely determine the actual state of the port. |
The port numbers are divided into three ranges:
