Virtualization Flashcards
It is a container for an
emulated computer
that runs an entire
operating system
virtual machine
Complete platform designed to
replace an entire physical
computer and includes a full
desktop/server operating system
System Virtual Machine
Designed to only run a single
process or application like a
virtualized web browser or a
simple web server
Processor Virtual Machine
Manages the distribution of the
physical resources of a host
machine (server) to the virtual
machines being run (guests)
Hypervisor
An attack that allows an attacker
to break out of a normally
isolated VM by interacting
directly with the hypervisor
VM Escape
It is known as bare metal, or native since it runs directly on the host hardware and functions as an operatin system. This is also more efficient that the other one.
Type 1 Hypervisor
Physical hardware that Runs in normal operating system
Type ll hypervisor
A single operating system kernel is shared across multiple virtual machines but each virtual machine receives its own user space for programs and data
Application Containerization
It allows for rapid and
efficient deployment
of distributed
applications
Containerization
Allows for
scaling up or down to
meet user demands
Elasticity
Contents of a virtual machine that exist as deleted files on a cloud-based server after deprovisioning of a virtual machine
Data Remnants
Occurs when a user is able
to grant themselves the
ability to run functions
as a higher-level user
Privilege Elevation
occurs when
a VM is moved from one
physical server to another
over the network
Live migration
Occurs when virtual machines
are created, used, and deployed
without proper management or
oversight by the system admins
Virtualization Sprawl
