I got the Following Messages from my Server -Admins and would like to know, what i can do, so this will never happend (also is seems that it has something to do with Cloudflare?). Can you please point me in the right direction?

It looks like the site was under an SQL Injection attack trying to insert code through the commenting system. This slowed down the site significantly as it had the similar effect of a DDoS attack.
The Cleantalk Spam Protect plugin was blocking it until the database was overwhelmed and the plugin could no longer read or write from it.
The IP address making the attack was 22.214.171.124 and showed up in an abuse database:
We’ve blocked that IP address in the server’s Firewall. Usually, Cloudflare will prevent this kind of attack before it reaches the server, but it looks like it didn’t trigger the flags in their system.

So, is it something, that i can do on the Cloudflare side?
