There needs to be a law that all nuclear and nuclear-adjacent facilities have no connection to the Internet. The fact it's allowed is unbelievable.

I heard that once you put up a website on the public internet, it would immediately gets attacked by all kinds of scanners or other worse things. Not sure if it's true as I'm not a web guy.

Every public IPv4 address is port scanned multiple times a day.

Which really isn't a problem, unless you're being scanned so much your bandwidth is being overwhelmed. Certainly not the case for me, despite having port 80 and 443 open

Watching my website's firewall and ssh logs show all the various hacking attempts is calming in the same way that watching waves crash on to the shore is.

I have a server that has a slow (5s) response to unknown pages, returns it as 200, and makes the next failing request even slower (for unauthenticated users). That seems to keep the number of requests limited. Perhaps I should just drop the connection after a certain number of requests.

BTW, quite a few of these port scanners are companies that offer to scan your ports for vulnerabilities. Temu pen testing, so to speak.

More like looking a thin net preventing mosquitoes from biting your skin, as there is some intention behind it, not just physics.

Do you configure this in your firewall? How can I replicate this?

Per day? per minute or second.

It's in the "404" handler of the backend. It should be possible to write a caddy or nginx module for it.

Damn that's like Blood War in DND...
