Virtual machines – Many of you have probably heard of him,
and/or self-used . But for those of you who don’t,
here is a brief description.
Virtual machines, or OS virtualization, allows heterogeneous
Operating systems simultaneously on the same physical
hardware. In a basic form, my Windows XP is running,
Windows 2003 Enterprise Server and Linux on the same
the computer at the same time. Each operating system virtualized
the system or the environment, it has access to the hard drives, memory,
video, input devices and communication devices, in all
at the same time in the same system.
Before the virtualization is at the end of this article about how to
use to quickly and securely deploy security toolsets, we
you are provided with links to Virtual Machine software,
can work with a trial bases (or purchase), and at least
a that free of charge.
How Do We Use Virtual Machines For Various Testing
Although the greater part of the work that we do is with security
assessment, we have begun to deploy security measures, such as
perimeter defense, or enterprise solutions firewall. Many
Sometimes it substitutes a different system of defence, and the need to
in order to ensure that, when we cut it on the new system
it will work correctly. For example, if
the deployment of a firewall, or firewall clusters, we can simulate
the cluster design, to install the software in the virtual
Machines on one physical system, and test internal
firewall-firewall communication. Also
the deployment of firewalls, we can create a virtual machine
Represent each network protected by the Firewalls and test
Connectivity / communication on each network, for example, the Internet,
private network, DMZ, and other protected nets, all with
only one system (usually a beefy laptop with a good piece of
the memory). This method of testing before cutting over
it turned out to be of inestimable value, and reduces the risk for serious problems
this could present.
How Do We Use Virtual Machines In Security Assessments
Every time that we perform an assessment of the safety for the customers
we utilize specialized and proprietary software / tools.
However, once the evaluation has been completed, and we move on
to begin the next test or new customer, we must come with a clean
Platform. We never used to install the same operating system or example
Tools for different testing phases or different customers.
With the help of virtualization, we’ve created in advance, many of the operating, have
Environments such as Windows, Linux, BSD, Solaris,
to mention some names, with the net installed and hardened operating system
Systems. This pre-made, secure environments also contain
all the necessary tools for the type of customer environment
and the security assessment that we are working on. Through the use of
The virtual machines, we can deploy our testing platforms within
Minutes, not hours, and feel confident that they are safe and
ready to work. In fact, we carry many of these
ready-to-go operating environments with us when we travel
high-capacity external hard disk drives-systems. In General, the
the size of a normal paperback.
How Else Can Virtual Machines Be Used
The application, use, and benefit of virtualization is very
width. For the people at home, or technical people who want to
to learn new operating environment, Virtual machines
great tool for learning. Instead of buying several
physical machines to install the operating system and
The applications that you want to, be formed, can be
Purchase a performance-based system, a portable computer, and
through the use of virtualization, you can run all of them at the same time. You can even
easily configured to communicate with the other.
The other “big” benefit in using Virtual machines, you can
be configured for use in a more effective and efficient
Your investment in hardware. For example, in place of
Purchase of two mid-range systems to run two different
Applications that you purchase, you could a virtualization
Running from side to side. In many cases, if with
dedicated systems for just one or two applications, the
hardware is not busy. It would be a good investment if
the server you purchased is only to say, “25”
Percent of its capacity / capability? Virtualization can
help you maximize the investment you will make in the performance
based systems, and has the added benefit of server
Then if you are curious about the Virtual machine
Technology, can be aspects b a great way to learn a lot of
the computer and network is essential. There are several great
The players within the virtualization industry, such as VMware.
VMware provides commercial virtualization products, even for
workstation or desktop environments. You can also visit
Xensource, an open source (no cost) to the Virtual machine
Solution. You must record a demo that can be downloaded, in CD form, and
the ship, or unload the entire product and
you install it on a dedicated system.
Regardless of the reason it has for us
Virtualization, I can say that this technology, such as
a great player in the near future. In fact, processor
the manufacturers themselves are taking steps to create processors
Virtual machine aware.
