Cloud computing has brought revolution in IT industry. There are major benefits of using cloud environment due to the better utilization of resources and reduced cost. Cloud infrastructure consists of the use of virtual machines like hypervisor etc. and it is similar to the large network. The cloud storage consists of huge amount of information and that can be shared from anywhere in the world with secure access. Wherever, the network is designed and internet is being used that becomes vulnerable to attacks. And as the technology is advancing, the cyber criminals have also become smarter and can identify the vulnerabilities, threats and can perform attacks on the cloud system. So,this paper aims at describing the different types of threats and attacks in the cloud infrastructure.
