The first and maybe one of the most important thigns you can do for yourself is signing up for a Life Lock account. Like, right now. Unfortunately it's a necessary evil at this point. For as low as $19.99/mo this is by far the cheapest thing you can do to bring yourself the most amount of security.
Personal Secured Server
Using a Raspberry Pi, ArkOS, you can become your own server. Hosting websites, files, email and more. Just plug it into your router. Web magic.
