Document some security guidelines for VM deployed on Cloud Compute

We could provide some security guidelines to Cloud Compute users, as an example:
* if a service is ACTIVE on port 80 THERE MUST BE a redirection (automatically or not)
to port 443
* if a service is ACTIVE on port 443 MUST
* ACCEPT only the following protocols:
* TLS 1.2
* TLS 1.3
* REJECT the following protocols
* SSLv2
* SSLv3
* TLS1
* TLS1.1

The following tools are available:
* to safely configure the server: https://ssl-config.mozilla.org/
* to check the solution adopted: https://github.com/drwetter/testssl.sh/tree/3.0
