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

the consolidation.



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.
