Nessus TCP scanner

info Nessus Plugin ID 10335
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


It is possible to determine which TCP ports are open.


This plugin is a classical TCP port scanner. It shall be reasonably quick even against a firewalled target.

Once a TCP connection is open, it grabs any available banner for the service identification plugins.

Note that TCP scanners are more intrusive than SYN (half open) scanners.


Protect your target with an IP filter.
