Ssh secure shell for workstations ftps windows#
If you’re thinking “well Linux, isn’t that popular compared to Windows so that must mean that Secure Shell is not that popular” you’d be wrong. Today Secure Shell is included with every distribution of Linux and Windows Server 2019. Towards the end of 1995, the SSH user base had grown to 20,000 users in fifty countries and in 2000, just five years later, the tool had over 2 million users. SSH was invented in 1995. So the protocol has been around since Bill Clinton was the President, Braveheart won the Academy Award and Gangsta’s Paradise was the jam in your Walkman cassette player. All of these send information, including passwords, in plaintext. SSH was designed as a replacement for Telnet and other insecure shell protocols such as Berkely rsh, rlogin and rexec protocols. It’s a popular misconception that SSH is an implementation of Telnet and that SSH cryptography is provided by SSL. This is especially important to ensure data confidentiality and integrity. SSH was invented to encrypt network services so malicious actors would not be able to eavesdrop on network traffic and see everything that was happening. So, if a bad guy gained access to your network he could ‘listen in’ to your sessions and see exactly what you were doing. But these original network applications did not use encryption. Those tasks are so common today we can’t even imagine life without them. Or imagine being one of the first engineers to be able to interface with a server when you’re not sitting at the keyboard in the same location.
But what does that mean? Back in the old days, imagine how cool it was to transfer a file from one machine to another. Secure Shell is a network protocol that was designed to operate network services securely over an unsecured network. What is Secure Shell? Why was it invented?
