So, you want to run a web server in your basement to create the next big thing, and you’re looking for some cheap security advice on how to get started? Well, my first and best suggestion is don’t do it. I’m just saying if NASA—you know, rocket scientists—can’t keep hackers out of its web servers, what makes you think you can? Go find some ISP that has the services you are looking for, and pay the ISP to do it.

Are you really still reading? Picture this: you find that perfect somebody. You plan a romantic evening and go out to a movie and have a nice dinner. Just when things start to get interesting your phone trumpets out the cavalry charge ring tone informing you of 15 unauthorized login attempts on the web server. After apologizing to those around you for disrupting their dinner, your date raises an eyebrow and decides to skip dessert.
Still there, eh? I’m sorry. I know, it must sound glamorous to have your very own web server, but unless you have spent time thinking like a hacker, odds are whatever you put on the Internet will be vulnerable to attack.
