How to protect against DDoS attacks?

Answer 1

Xpl0it Yes True, I'll add a point that you have to make algorithm to check against maximum requests allowed per ip, otherwise sometimes high trafic will let algorithm think it is DDoS attack

Answer 2

You could also use a service like Cloudflare and outsource that work so you don't have to handle it if you don't maintenance your own servers.

Answer 3

Try writing an algorithm to check against more requests than acceptable. If it makes too many requests and does so from proxies, create a method for handling those requests.

Answer 4

Good looking out. But I usually blast my requests to run on multiple threads from different ips every 30 seconds. I can see what you're saying but I think it really depends on the severity of the attack.

I might add, make sure you also add in a check and balances script to the algorithm to make sure your script isn't accidentally running the requests against itself during this phase or else if you have a root kit in your system, you may end up DDoSing yourself.
