Hi, recently (ironically, right after sharing some of my posts here on Lemmy) I had a higher (than usual, not high in general) number of “attacks” to my website (I am talking about dumb bots, vulnerability scanners and similar stuff). While all of these are not really critical for my site (which is static and minimal), I decided to take some time and implement some generic measures using (mostly) Crowdsec (fail2ban alternative?) and I made a post about that to help someone who might be in a similar situation.
The whole thing is basic, in the sense that is just a way to reduce noise and filter out the simplest attacks, which is what I argue most of people hosting websites should be mostly concerned with.
As a side note, don’t be cute and pick port 221 or 2222 or 22022 or whatever that’s got “22” in it.
I know that sounds silly but the slightly less stupid bots are written by people who understand people do things like that and account for them, and thus port 2222 isn’t actually better than 22, or whatever.
