Cloud computing is the most important technology at
the present time, in terms of reducing applications costs and
makes them more scalable and flexible. As the cloud currency is
based on building virtualization technology, so it can secure a
large-scale environment with limited security capacity such as the
cloud. Where, Malicious activities lead the attackers to penetrate
virtualization technologies that endanger the infrastructure, and
then enabling attacker access to other virtual machines which
running on the same vulnerable device. The proposed work in
this paper is to review and discuss the attacks and intrusions that
allow a malicious virtual machine (VM) to penetrate hypervisor,
especially the technologies that malicious virtual machines work
on, to steal more than their allocated quota from material
resources, and the use of side channels to steal data and Passing
buffer barriers between virtual machines. This paper is based on
the Security Study of Cloud Hypervisors and classification of
vulnerabilities, security issues, and possible solutions that virtual
machines are exposed to. Therefore, we aim to provide
researchers, academics, and industry with a better understanding
of all attacks and defense mechanisms to protect cloud security.
and work on building a new security architecture in a virtual
technology based on hypervisor to protect and ensure the security
of the cloud.
