Thank you for the video tutorial “How to install Magento 2.4 and build a web server”.
There are some things to be done from there - and perhaps you can help with hopefully another video or provide instructions:
Most importantly, hardening the server (not just Magento) from attack - anything from apache config changes, to better firewall protections, and .htaccess lines etc etc.
I understand that it is one thing to install a web server, but quite another thing on how to 1) protect it, and 2) maintain it…
Also, other things may be useful - Installing and configuring at least DNS, and cPanel or a cheaper Vesta panel product, and other useful utilities.
Given you experience setting up servers for a living, perhaps you could help.
