How to solve DDOS attacks in Windows Server 2008 R2 / Windows Server 2012? [closed]

Solution 1:

You could not solve ANY Ddos problems with software.

Counteracting a Distruibuted Denial Of Service attack is not a software problem. It is simply your server is being overloaded with more requests than it can handle. Also it may not be your hardware that fails. If the router your ISP is providing you can not handle the volume of connections no amount of software on your server will help your ISP's hardware.

The only thing to mitigate DDOS attacks is somewhere upstream from your server you either need to filter the incoming requests before it focuses on a single server or distribute the requests across multiple servers. Both of these things are properties of Load Balancing

Think of it like a magnifying glass. Putting your hand in the sun does not hurt, it just makes it warm. However if you use a magnifing glass and focus all that area that was covering your hand to a single point it will burn you. Your server is that single point, what you need to do is put your mitigation solutions up at the magnifying glass level, if you are at the focal point of the hand you are too late to do anything.
