The Internet Is a Rough Neighborhood
This week I stood up a new firewall in front of my home network. This one has much better logging than the old one, and I've been watching the block reports.
Real talk, friends: DO. NOT. expose a machine to the open Internet unless you're 100% confident it's bulletproof.
"I run my service on a custom port!" Doesn't matter.
"I use IPv6!" Doesn't matter.
"I'm just a nobody!" Doesn't matter.
Practice safer networking, every time, all the time.
