PuTTY is a free and open-source terminal emulator application which supports several network protocols (including SSH). And Windows users pre-Windows10 (which has SSH compatibility built into it) can take advantage of something called PuTTY. SSH can be used by any Linux or macOS user. no longer require the admin to be in-person.

Managing systems and applications, interacting with the command line, delivering software patches, etc. With its strong encryption, SSH is often used by network admins to access remote assets. SSH is a cryptographic protocol that provides a secure access to computers over an unsecure network. The need for a secure, Telnet-like protocol led Secure Shell Protocol (SSH) to gain quick popularity once created in 1995. Telnet is outdated and shouldn’t be used over the public internet. Some still use this protocol but largely in a LAN for obvious reasons. By using Telnet over the internet, someone could easily eaves drop and grab any sensitive data being sent across its network. This leaves data vulnerable to possibly going through a machine that’s unsecure or has malicious programs/users listening for interesting requests. As data is sent through the internet, it makes its way through many networks to make a remote connection. Unfortunately, this lack of security became problematic when people started making transfers over the internet.
Hence the protocol’s design to send commands in clear text without encryption wasn’t an issue. When Telnet came about in the pre-internet era, security wasn’t a major concern. Running programs, managing folders and files, browse directories, and starting/stopping services become possible to accomplish remotely with this protocol. One could administrate a server from miles away as if sitting right in front of it. Telnet was developed in 1969 as a simple command line tool (no GUI) that enabled commands to be sent remotely to a server. To understand the purpose and importance of SSH’s, it’s valuable to know about the Teletype Network (Telnet) protocol.
