Traditional threats include: network eavesdropping, illegal invasion, and denial of service attacks, but also specific cloud computing threats, such as side channel attacks, virtualization vulnerabilities, and abuse of cloud services. In order to mitigate these threats security controls often rely on monitoring the three areas of the CIA triad.
Hyperjacking is an attack in which a hacker takes malicious control over the hypervisor that creates the virtual environment within a virtual machine (VM) host. [1] The point of the attack is to target the operating system that is below that of the virtual machines so that the attacker's program can run and the applications on the VMs above it will be completely oblivious to its presence.
Cloud computing offers many benefits, but is vulnerable to threats. [60] As cloud computing uses increase, it is likely that more criminals find new ways to exploit system vulnerabilities. Many underlying challenges and risks in cloud computing increase the threat of data compromise.
Today, companies such as Reflex Security and Blue Lane that are virtualizing intrusion prevention, firewall and other application layer technologies. These goals are challenged with delivering optimal performance levels because in the virtualized world, applications running on operating systems compete for the same hardware computing resources.
VMI-based approaches are widely used for security applications, software debugging, and systems management. [1] VMI tools may be located inside or outside the virtual machine and act by tracking the events (interrupts, memory writes, and so on) or sending the requests to the virtual machine. Virtual machine monitor usually provides low-level ...
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.

The primary purpose of a virtual security switch is to provide security measures such as isolation, control and content inspection between virtual machines. Virtual machines within enterprise server environments began to gain popularity in 2005 and quickly started to become a standard in the way companies deploy servers and applications.
In theory, a virtual machine is a "completely isolated guest operating system installation within a normal host operating system", [2] but this isn't always the case in practice. For example, in 2008, a vulnerability ( CVE - 2008-0923 ) in VMware discovered by Core Security Technologies made VM escape possible on VMware Workstation 6.0.2 and 5.5.4.
