Description: Finger servers provide information about the users of their computers by opening and listening for incoming TCP connections on port 79. Remote users wishing to obtain information about the user of a specific computer could do so by querying their machine's finger server listening on port 79.

Port 79 is used for the Finger protocol, which provides information about users on a network. One cybersecurity concern related to Port 79 is that it can be exploited by attackers to gather information about users, potentially aiding in reconnaissance for further attacks.

Port 80 is the default network port for web servers using HTTP. It operates on the application layer of the TCP/IP networking model and serves as the communication gateway for HTTP requests and responses between client computers and servers.

TCP/IP Ports Registered ports are from 1024 to 49151. The remainder of the ports from 49152 to 65535 can be used dynamically by applications. A brief description of these are as follows: Port 20 and 21: FTP data and FTP control, respectively.
