# Day 6 #90DaysOfDevops

For day 6, i moved to topic 4: SSH.

Based on what i understood, Secure shell (SSH) protocol is a method for securely sending commands to a computer over an unsecured network. It uses cryptography to authenticate and encrypt connection between devices.

SSH has the ability to do a remote encrypted connection and also the ability to tunnel: In networking, tunneling is a method for moving packets through protocols or paths that are ordinarily not used.

SSH works with TCP/IP, authentication, cryptography adnd not limited to funnelling.

This is the theory aspect i could get a grip on. SSH is pretty straightforward and working with it is going to broaden my understanding deeper and deeper.

So to go into the pratical aspect, i discovered i needed an instance from AWS which i can’t create now as my account isn’t ready.

For tomorrow, i would go back to day 1 and revise everything i have learnt and try my hands on the different platforms.

Cheers to day 6 and cheers to many more days!
