Once upon a time, security of our systems was up to us to manage. Choosing a more secure system against malware, making smart installations and regularly updates of the software, backing up data, hardening the OS and encrypting the disks was a good way to live secure with our data.
Today this scenario has changed or, better to say, extended. To be clear, all of the previous steps are today valid to build your local system but the reality is that only a little bunch of our data resides in our property memory devices.
A big part of our life is stored somewhere far away from us, managed by someone we don’t know in a system we miss the implementation design where happens things we are totally unaware of!
