There are different types of attacks on cloud by intruders or outsiders. They are classified as denial of service attacks, cloud malware injection attacks, side channel attacks, authentication attacks and man in the middle attacks. In this paper, the authors focus mainly on DoS attacks. Denial of Service (DoS) attacks mainly focus on web resources, which are provided by cloud service providers. Denial of Service (DoS) makes the cloud servers unavailable to the end users. In a cloud environment DoS attacks are great security risks since the resources are shared by multiple users in the cloud.
