Some basic design features in a virtual environment can help mitigate the risks of hyperjacking: Security management of the hypervisor must be kept separate from regular traffic. This is a more network related measure than hypervisor itself related. [1] Guest operating systems should never have access to the hypervisor.
Penetration testing is the process of performing offensive security tests on a system, service, or computer network to find security weaknesses in it. Since the cloud is a shared environment with other customers or tenants, following penetration testing rules of engagement step-by-step is a mandatory requirement.
In computer security, a sandbox is a security mechanism for separating running programs, usually in an effort to mitigate system failures and/or software vulnerabilities from spreading. The sandbox metaphor derives from the concept of a child's sandbox—a play area where children can build, destroy, and experiment without causing any real ...
The virtual access layer (VAL) refers to the virtualization of the access layer that connects servers to the network in the data center. Server virtualization is now aggressively deployed in data centers for the consolidation of applications hosted on x86 servers. However, the underlying limitations in current networks prevent organizations ...
It is called an appliance because it is pre-packaged with a hardened operating system and a security application and runs on a virtualized hardware. The hardware is virtualized using hypervisor technology delivered by companies such as VMware, Citrix and Microsoft. The security application may vary depending on the particular network security ...
In computer security, virtual machine (VM) escape is the process of a program breaking out of the virtual machine on which it is running and interacting with the host operating system. [1] In theory, a virtual machine is a "completely isolated guest operating system installation within a normal host operating system", [ 2 ] but this isn't ...
Unlike physical networks that have switches with access control lists (ACLs), firewalls, antivirus gateways, or intrusion prevention devices, the virtual network was wide open. The virtual security switch concept is one where switching and security have joined forces, so that security controls could be placed within the virtual switch and ...
