“In the time of free wifi and free internet connections in every
hotel, bar or cafe you should be sure your connections are secure.
In some cases you can’t trust the connection but you need to go
online and read some mails or share some documents. In this case
some basic tools like SSH and Firefox can help you to build an
secure connection to an known computer in the internet you can
trust (for example your own root server).“To make more clear what I am talking about i created this small
diagram to make it more easy for me to explain what I am doing with
this SSH connection and how I can benefit from it.”
