Simplified IT management: VDI removes the need for manual configuration on each system. It makes it easy to provision desktops and lets admin configure their network setting, run desktop apps, and add users in just a few clicks.

How Does VDI Work?

A VDI environment can become less complex than any remote desktop environment because it is supported by an extensive collection of VMs that run on top of hypervisor software.

It uses server hardware to run desktop operating systems like Linux or Windows on a VM hosted on a centralized server at a data center. Furthermore, cloud providers offer two major virtual desktop types: persistent and non-persistent. They both have their advantages.

Persistent virtual desktops are for developers and cybersecurity professionals. It has a persistent environment that requires elevated permissions. These DVDs are cheaper as they offer personalization and app compatibility.
Non-persistent VDs offer a high level of personalization, but they separate the personalization layer from the underlying OS. This personalization option is removed once the user signs out. It comes cheap and is a good option for task workers in call centers, retail stores, and computer labs.

What are the Security Risks Associated with VDI?

VDI is known for its various benefits and robustness in security. However, it also has some unique security risks. So, along with getting to know what is VDI in cybersecurity and its benefits, you must understand that it also comes with the following security risks –

Unpatched Virtual Machines

If there are any unpatched virtual machines in the network, it can expose the network for a long time. It may take time for professionals to patch the machines to make the security back up again. This time gap makes systems vulnerable to security breaches and makes all the routers and links in the system vulnerable to cyber-attacks.

Network Vulnerability

Although VDI tries to maintain solid security by encrypting the files, a minor security breach can risk all the links and routers in the VDI infrastructure. These virtual networks are more prone to cyber attacks as physical resources are operated in a shared network.

Hypervisor Compromises

The hypervisor of the operating systems can be hijacked using malware attacks by people. These attacks can burrow beneath the secure network of the operating system. They can be used to access the hypervisor, allowing the hacker to access all the virtual assets. This attack compromises the access to the core servers so the person can gain access to the network and manage storage.

Human Error

It is optional that everyone working in a company knows what is VDI in cybersecurity, and they unintentionally do something that can compromise the network. For instance, they can break into the server room, directly compromising the server.

Best Practices for VDI

VDI can be a valuable tool for managing the security risks associated with remote work. However, these solutions carry many security risks and can be a liability if they are not properly designed, configured, managed, and deployed. To ensure the correct implementation of VDI in your data center, follow the given best practices:
