- which process uses each internal or external connection.

What it's good for
Locating traces of malware activity on a PC or server. Find out which ports and which processes are involved in the system. It will also help system administrators conduct a quick diagnostic of the local network and devices connected to it.
It will also be useful for testing LAN security because it displays a list of all open ports that could theoretically be used for hacking. To protect the network it will be enough to close them in the server or router settings.
