Why don’t you use an open source HIDS like ossec, and modify the rules if need be? Worse comes to worse, just use fail2ban

Sweet, good advice, it's working good. I assume I have to manually enable some actions, but it's much easier than watching logfiles!

This guy is hitting all angles:

[Tue Jun 12 16:35:24.396912 2018] [proxy:warn] [pid 26766] [client 51.15.56.143:58380] AH01144: No protocol handler was valid for the URL http://66.135.33.212:80/phpmyadmin/. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

Damn. So now I can use this to automatically update blacklists and get more pre-emptive?

This is ridiculous.

Not sure which one you setup, but I would imagine fail2ban. At any rate, then you can perform an iptables -L, and that will show you exactly the rules that are being triggered. If you are not seeing anything, you may need to go through your config files in /etc/fail2ban , just make sure that if you are making changes to use the jail.local file, as the other will be overwritten upon system updates.

BTW, while ossec is a lot harder in the beginning, it is a lot more efficient when you figure out how to generate your own rules when you get hit by something more than the usual script kiddies.

This looks very promising. It's running now we'll see what it can do.
