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.
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.
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.
Two higher education institutions in Springfield, Ohio, have been forced to make changes to their schedules following threats surrounding unverified claims that Haitian immigrants were stealing ...
Solutions to various cloud security issues vary, from cryptography, particularly public key infrastructure (PKI), to use of multiple cloud providers, standardization of APIs, and improving virtual machine support and legal support. [54] [58] [59] Cloud computing offers many benefits, but is vulnerable to threats. [60]
The type of security technology is irrelevant when it comes to the definition of a Virtual Security Appliance and is more relevant when it comes to the performance levels achieved when deploying various types of security as a virtual security appliance. Other issues include visibility into the hypervisor and the virtual network that runs inside.
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 ...
