Background: 15 years of experience in software and apparently spoiled because it was already set up correctly.
Been practicing doing my own servers, published a test site and 24 hours later, root was compromised.
Rolled back to the backup before I made it public and now I have a security checklist.
Yeah I don’t do security via obscurity :D I agree you need to keep your Internet facing services up to date.
(No need to educate me on Wireguard, I use it. My day job is slightly relevant to the discussion)
