What is Virtualization? | Hypervisor | Virtual Machine | the Importance of Information Security Policies
65. What is Virtualization and why are information security policies important, and do you offer comprehensive I.T. security documentation?
Virtualization is the process of partitioning physical computing resources into logical elements, thus resulting in logically isolated, stand-alone instances, such as servers, and their underlying operating systems and applications. There are, however, three (3) primary types of generally accepted virtualization environments: Network, Storage, and Server virtualization, with server virtualization being the most common. As for the core components of virtualization, you’ve probably heard the terms “hypervisor” and “virtual machine”, which are the following:
Virtualization | Hypervisor | Virtual Machine Monitor | Virtual and Guest Machines
A hypervisor (also called virtual machine monitor or virtual machine manager) is critically important, as it serves as the program residing on the actual “bare metal” hardware of the physical machine, effectively allowing multiple computing resources (i.e., operating systems) to run on the machine ( i.e., host computer). This in turn allows guest machines (i.e., virtual machines) to “think” they have their own resources, ultimately allowing for virtualization to work.
As for the virtual machine, which is often called a “guest” or “instance”, it’s a self-contained computing resource with its own operating system, and other necessary resources. It functions independently - logically speaking - from the virtual machine monitor, yet requires the underlying resources from the VMM to work. Virtualization is the way of the world, so gaining a stronger understanding of this important topic is a must for technology professionals.

Just as virtualization is fast becoming a very standardized I.T. platform, the need for securing and putting in place formalized practices regarding a whole host of measures for this quickly maturing technology is a must. What organizations need are comprehensive, well-defined, and professionally written operational and information security policies and procedures, such as those offered by us with the FLANK21 set of documents. With literally hundreds of essential forms, checklists, templates, provisioning and hardening documents - and more - to choose from, the all-inclusive set documents is a must-have for virtualization environments.
Information security is a serious issue for organizations, and the growing using of virtualization platforms only increases the need for well-documented, enterprise-wide operational and information security policies, such as those offered by FLANK.
