How to fully set up security when accessing XAMPP Localhost from the Internet?

Question

Information Security

Interested in firewall settings Windows and Linux. What traffic checking programs to use?

Answer 1

You just need to forward / tunnel the necessary ports of the Jabber / XMPP protocol to the "white" IP.
And bind the domain name to the IP and set up SSL certificates.
The security of the request-processing server application depends on itself.

Answer 2

completely - no way.
any firewall, as always - allow what you need, and prohibit the rest.
