I'm running windows server 2012 R2. Looks like someone attempted to hack us, as we had over 3800 https requests in a few minutes on our webserver, which crashed our server. The 3800 requests all came from 4 different IP addresses in a few minutes time.
Is there a way in IIS to limit the total number of connections per IP address?
Basically, I want to stop what just occurred this morning from happening in the future.
I came across this, but this limits the total connections for the server, there's no option for limiting connections by IP address.
I don't want to limit the total connections for the server because then I can be limiting legit traffic.
During this time, my SQL server was running at 99%, so it stopped everything.
Any thoughts how to solve this issue?
