The 21st century has given rise to a wealth of advancements in computer technology. Among these are virtual tools and programs that have applications in almost every industry imaginable. One area that virtualization technology is making a huge impact is the security sector.
How Is Virtualization Technology Used?
Virtualization is a technology that can create servers, storage devices, and networks all in virtual space. Devices connect to a virtual network to share data and resources. This allows users to interact with any hardware resource through a digital interface.
A great example of virtualization technology is cloud computing. One of the most significant advantages of virtualization is the ability to store many types of data in cloud servers. Then, you can access them whenever you want from anywhere as long as you can access the internet.
Virtualization can allow you to manage all your physical or digital assets simultaneously. Before, business owners had to be on-site to address their companies. Virtualization can enable them to run every aspect from the comfort of their homes.
Virtualization and Security
The speed and ability to create virtual environments have many applications in cybersecurity—these range from the prevention of cyberattacks to the protection of digital resources.
1. Containing Malicious Software
The greatest strength of virtualization technology is its ability to create and manage virtual spaces quickly. Resources in a virtual network can be moved and cut off from others at will, whether they are hardware or software.
Isolating an area from the rest of the network is a considerable cybersecurity advantage. If a malicious program invades the network, virtualization makes it easy to trap it.
This can prevent it from escaping any critical data and stop it from damaging other critical systems. Cybersecurity professionals can then analyze and pick apart the program to find its origin and report the hacker to the authorities.
2. Isolating Critical Processes
Virtualization technology can also be used as a defensive measure to isolate the most critical parts of the network. For example, sandboxing is a process in which untested programs run in a virtual environment to share data.
The sandbox intermediates untested, vulnerable programs and more critical operations. Interacting this way allows them to share information without making core processes vulnerable to cyber attacks.
If malicious software can infiltrate your network through these untested programs, they will not be able to reach any of the more critical processes. Instead, the malware will be trapped in the sandbox, unable to escape.
3. Hypervisor Security
Hypervisor refers to any small hardware or software device that creates and runs virtual machines. These programs enable the virtualization of the development, implementation, and management of devices in the network.
Hypervisors are located in the host computer and are usually isolated from the rest of the network for security purposes. Users can quickly create and manage their virtual machines through the hypervisor. This can also allow them to adjust rapidly and adapt to any malware entering the system.
Virtualization Can Be a Powerful Security Tool
The strengths and abilities of virtualization are a powerful asset for your cybersecurity measures. For example, separating and changing the network structure quickly can deal a decisive blow against cyberattacks attempting to disrupt your system.
