In the aeon of the internet, storing your files and important document in the traditional environment which used limited space to store was starting to become inconvenient. The availability of document is becoming prime priority. So, the concept of storing data on the cloud came into view. As the time passed the cloud was further divided into public, private and hybrid to fulfil different purposes. Distributed denial of service (DDoS) attack is one of the attacks, which has an immense danger to the availability of the internet. Cloud has many securities promoting among which DDoS attacks have prime priority. Cloud Security matter being premier for the private enterprises, the denial of service attacks is rated as the highest priority threat. One of the huge problem is to find the details of attack as many organization hold off to revel that they were attack due to the panic of the scandal. It exhausts victim’s bandwidth. In this paper an overview of distributed-denial-of-service, different types of attack, different types of techniques, and their countermeasures [23].
