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.

    Some people also swear by other measures, like changing the SSH port to something else. Most people end up using 2222 to easily remember. This is borderline useless, as you can see for yourself.

    While being useless against a sophisticated attacker, there hasn’t been any bot activity in my sshd logs since changing my ssh port to a different one.

      Yeah, what I mean is that it’s useless using ports like 2222, that’s like the unofficial SSH port! Bots are generally harmless (once you move to key auth), and you get functional the same result with the automatic IP ban on failed auth, minus the bother to change client configurations to your custom port. Anyway, if someone does want cleaner logs, changing port works :)
