Ncat command in Linux or NC command is used in the maintenance or diagnosis-related tasks for a network.
Even though the “nc command” or “ncat command” are separate commands but they are similar to how they perform their functions & one can be used or replace by the other. Similar to how CAT common in Linux has the ability to manipulate files, the NC command in Linux has the ability to perform operations like read, write, or data redirections over the network.
The ncat command can be used as a utility to scan ports, monitoring or can also act as a basic TCP proxy. Organizations can utilize it to review the security of their networks, web servers, telnet servers, mail servers, etc, by checking the ports that are opened or unsecured and then secure them. NC command can also be used to capture information being sent by the system.
