Even though remote work has been with us for some time, the popularity of VDI continues to grow. Virtual desktop infrastructure (VDI) is almost like your home desktop, but the connection to it is done virtually. It’s the best solution to allow you connecting to your workspace from any device and any place. The specifics of the technology is that the virtual environment is hosted on a centralized server. The network delivers it to various devices, whether you work on a laptop or a PC.
However, the comfort of VDI goes hand in hand with the security vulnerability. It is mostly linked to remote access and data centralization. That’s why ensuring data protection is a must for any company using VDI.
Let’s dive deep into the major threats that emerge with VDI implementation and the most effective security measures we can implement in our working space.
VDI allows us to have all the data stored in one place, usually in a cloud or in a data center. We used to think that VDI for a small business can be a good secure solution. The security measures can be implemented on the server without the need to do the same on every employee device. But the truth is, you may still experience a number of serious threats. Here are the most common ones.
Virtual Desktop Security Threats
If a proper security is not duly established, the threats can occur on numerous levels, bringing potential security breaches and leaks. We can regroup them into the following categories:
- Data breaches. With data breaches, someone unauthorized can get access to your sensitive information.
- Insider threats. Mostly coming from insiders, that is, your employees who have access to VDI, this virtual desktop security threat can be difficult to detect at first glance. Some examples include unauthorized installations, misuse of security protocols, and the lack of access control.
- Malware attacks. These threats can penetrate the VDI environment through connected end user devices. In the form of viruses, keyloggers, or ransomware attacks, they can be devastating to your operations.
- Network weaknesses. Insecure firewall configurations, open ports, or DDoS attacks all sit in this category. This threat targets login credentials, unauthorized accesses, and the whole virtual desktop infrastructure security.
- Compliance risks. Not following local and industry security requirements may also compromise your security, putting sensitive data at risk.
Best Security Measures for Safe VDI
It seems that a virtual desktop security is something evanescent that is difficult to control. But, a couple of existing measures can make the protection stronger and even eliminate these threats.
Multi-Factor Authentication (MFA)
This is one of the most widespread VDI security measures, also known in our everyday life. Asking an extra verification question in addition to a usual password will add an extra layer to your company’s security.
Data Encryption
The encrypted data becomes unreadable, even if the access to it is stolen. This extra step of protection should be implemented on both data at rest and in transition. The first one will be encrypted while not in use. The second one supposes encryption to protect transition of data from the VDE to the end device.
Network Security
VPN (virtual private network) is in the top most popular VDI security measures. Many companies use it for their remote connections. Beside it, you can implement firewalls and intrusion detection and prevention systems (IDPS) to control traffic.
Endpoint Security
This security level is an additional step established on the side of the end devices connected to VDI. It usually includes all sorts of malware detection software, compliance checks, and patch management. The last one serves to check across all software connected to VDE. The extra measures can include the authentication measures to access the device (such as the usage of cards, facial recognition, other encryption).
Data Loss Prevention (DLP) Tools
DLP tools typically combine multiple technologies. Their tasks usually contain content inspection, data classification, policy enforcement, and monitoring of users’ activity. Such tools are secure from data leaks and prevent data and privacy threats. They can be installed both on the server and the end device sides.
Concluding Thoughts
In our workspace requiring flexibility, virtual desktop environments stand from the crown fulfilling our needs. Though, we should understand that all beneficial solutions come with their own risks. By understanding the inherent security challenges of VDEs and implementing robust security measures, you can create a secure and trustworthy environment.
