Know what virtualization is and how it creates a virtual computing system

New Delhi. At present, all of our data has been digitized. In such a situation, it is very important for us to pay attention to its safety. If we are not careful about the security of our digital data, things like our personal, business data and documents can also be stolen. To strengthen our security, we take the help of virtualization.

Virtualization software forms an abstract layer over our physical hardware. By doing so, it creates a virtual computer system, called a virtual machine (VM). With its help, any organization can run many virtual machines, operating systems and applications on a physical server. Let us know how virtualization can increase our security.

1. Containerization
One of the latest methods of virtualization is containerization. It is also called virtualization at the operating system level. In this process, the operating system creates a separate and completely isolated space for each application so that all applications feel as if it is the only application running on the system.
From a security perspective, applications cannot see each other and are therefore secure.

2. Sandbox
Sandboxing is a very popular mechanism. It runs programs that run untested code separately from unknown websites, parties or vendors. It helps to isolate the application to protect it from external malware, virus or any threat. By isolating it in this way, it protects the system from untested code or applications.

It can be used both in the operating system and in the application. It gives you an environment to run the application on the operating system where no other application has access. At the same time, if we talk about the application level, it works for you to run the application and analyze its security.

3. Server Virtualization
With this technology, server resources can be hidden and can also be maximized. Virtual servers can run and restart independently. Another reason to use it is that it abstracts under your operating system and virtualizes the hardware. You can isolate applications without any compromise through the use of virtual servers.

4. Network Virtualization
In this method, software and hardware network resources are combined to provide a virtual network. This network virtualization creates a logical virtual network using the underlying hardware network and connects it to a virtual network. There are two types of virtual networks. First isolation and second segmentation.

Isolation and segmentation network
Isolation allows the coexistence of many different virtual networks that are known to provide end-to-end cloud services. Segmentation divides a network into multiple subnets, so the traffic passing through them can be reduced and performance can be increased. It also hides the internal network structure, which makes it more secure.

5. Workstation virtualization
Desktop virtualization is a form of virtualization that allows users to create, patch, or remove images of the physical computer used for access.
Administrations find desktop virtualization to be very useful as it makes it easy to manage their employees’ computers, making it easier for them to update the source from time to time or remove unauthorized access.

Therefore, your computer is not exposed to any malware as long as proper configuration, protection and permissions are adopted. Apart from these, there are many other virtualization methods using which we can further increase our security.
