hi guys, during these weeks i've been affected by a ddos attack that caused big problems.
Bitnami 's stack is under cloudflare and reading analytics, has been made 4M of request just to the domain. If we consider also direct request to the ip we think we reached 8M of request during last month.
We increased performance of our machine in aws but now is the time to get a firewall and start protecting the hardware.
What firewall do you suggest that can be installed easily on bitnami stack?
and in your opinion which metrics can i directly measure to be ready for a suddendly attack?
Thanks for help.
