I have an overview ideas of the preventing ddos attacks, in a simple way. Please clarify me, if my thinking is wrong.
From the basic understanding of the DDOS attacks is that the attacker is sending a lot of data to the web server. So what about the website that offer big data uploading to their website? Aren't they not also receiving a lot of data at the same time from many uploading users?
Can't the web server treat the ddos attacks like a many users uploading data?
What about a website offer, everyone who visit the website temporary key? With that temporary key insert into the website, the only one (PC/IP) can access that website, so bot-net can't attack the website (bot-net doesn't have the temporary key). Can bot-net note the key and insert into the website?
This is the similar question DDoS - Impossible to stop?
