With the internet being so ubiquitous these days there are times when you want to use it to your advantage even at work. For example, let’s say you want to stay home from work today. But you still want to be able to get work done. What can you do? Well, if your job has this sort of set up, you can use a tool named SSH to securely connect to your computer at work and get the files that you need. You can then place them on your computer at home and do your job from there. SSH is a great tool for this purpose.
What does SSH do exactly?
The letters SSH stand for Secure Shell and are actually a protocol for network communication. It is the replacement for outdated technology like Telnet. Telnet would transmit your information in plain text. If anyone was able to get in the middle of the broadcast between the telnet client and the remote computer, they would be able to read everything that was typed. An SSH shell is encrypted so you do not have to worry about man in the middle attacks like this. You see a lot of people who work with the internet such as IT admins and programmers use SSH shells a lot.
But as important as SSH is, it loses all meaning if you are not able to keep track of your password. The encryption key of your SSH session is stored in a RSA file somewhere in your computer. But you need the password that you set up in the beginning to be able to use SSH. If you do not keep it safe then you are in trouble.
Plus you have to remember that the servers that you are logging into need passwords as well. So make sure you keep track of all the different servers that you use and the passwords for them. If you do not then you will find that your SSH client is going to fail you at the worst time. And it will be your fault.
