Common Threats of Cloud Computing {2}

by Edwin T
The peer reviewed article i chose for this weeks post is about the services that cloud providers are offering that can be potential threats. The article focuses on virtualization and the impact it has on cloud security. As we already know, virtualization means that a single physical machine known as a host can run multiple operating systems at the same time, known as virtual machines. The first threat discussed is VM Hopping. With VM hopping, an attacker has control of one virtual machine and tries to gain control of another. VM hopping is a considerable threat because serveral VM’s can run on the same host making them all targets for the attacker. Another threat that caught my attention was the VM Denial of Service. “VM’s share physical resources, such as CPU, memory disk, and network bandwidth.” DoS in virtualization happens when one machine uses all of the resources. Making the host unable to launch more VMs, preventing the service. One effective way to reduce the occurance of a DoS attack is to limit the resource allocation for each machine. read more...
