This is my first time putting a guide like this together. I see a lot of really great feedback and I will be incorporating them into future updates.
I don't have time today but I will reply individually to all the comments that I can.
I appreciate any/all feedback/advice. If possible, could future issues be submitted to GitHub because it is easier for me to manage if everything is in one place. https://github.com/imthenachoman/How-To-Secure-A-Linux-Serve...
But right now I need to find all the other places this guide is linked to with comments so I can address them too. :)
