Today, virtualization technology is gaining momentum as more corporations continue to embrace it in conducting business operations. Microsoft launched Hyper-V, also known as a Hypervisor, a unique innovation that allows end-users to create a virtualized environment conveniently. You can quickly implement a Hyper-V backup solution for your virtual machines due to its flexibility and efficiency. With the upsurge of cyberattacks across the globe, Hyper-V is also susceptible to these attacks. Malware and virus attacks can infect your Hypervisor and compromise your sensitive information. Thus, it would be best if you implemented strict security measures to prevent these threats. Click here and get an in-depth understanding of Hyper-V technology and how to back up your files in a virtualized environment.
This article helps you understand the threats that can attack your Hyper-V and safety precautions to avoid data loss. Before we proceed, let us define the meaning of Hyper-V.
What Is Hyper-V?
It is a modern innovation from Microsoft that permits individuals and organizations to create virtualized computing environments. ...
... The technology allows a single host computer to run under multiple guest operating systems.
Below are the threats that you must beware of in 2020 that can affect your Hyper-V system.
Hypervisor Malware Attack
VMs are prone to malware and virus attacks, just like the standard computers. One virtual machine may be infected with Trojan malware, which eventually moves to the public clouds to search for vulnerabilities. If the infected VMs are running on the same proxy with the hypervisor, the malware will spread and infect the Hyper-V. Or you may download a virtual appliance from a trusted cloud provider without understanding the risks. A cybercriminal may have access to a compromised VM in your environment without your knowledge.
You can prevent the attack by verifying and testing all the backup appliances. Ensure that your cloud service provider is reliable and has configured the network and hypervisor as required to avoid proximity issues that might cause vulnerabilities. Furthermore, don't forget to isolate each VM in the environment by configuring the systems correctly.
Improper Firewall and Network Configuration
In the traditional backup setup, the networking staff was responsible for configuring firewalls and other networking components. They tag, route, and connect the LANs as required while understanding the security risks of improper configurations. However, in a virtualized environment, the host administrators handle the networking devices and configurations for the VMs. If one VM is improperly configured, it can affect the entire environment. The hypervisor might not function as required due to irregular resource distribution to the virtual machines. Furthermore, erroneous firewall configuration may open loopholes for cyberattacks.
Since this threat is due to human error, you can counter it by ensuring that you have a competent network team to work on the networking section in the virtualized environment.
Improper Hypervisor Configuration
A virtualized environment must be highly secure to protect the hypervisor from any external threat. If a hacker gains access to the Hyper-V, the entire virtualized environment is under attack. Therefore, administrators must limit access to the Hypervisor to prevent third-party risks. In an organization, not all employees have a genuine interest; some are malicious and can steal sensitive information for their personal gain. Thus, it is critical to configure the Hypervisor to allow access to only authorized personnel. Also, administrators should be careful of users who access the Hyper-V via untrusted Internet networks since it can escalate cyber-attacks' risks.
IT administrators can reduce this risk by implementing strict access controls limiting unauthorized users from accessing the Hyper-V and other sensitive management functions.
Data Leakage
Virtualized environments sometimes experience data leaks when the images in the guest operating systems get suspended. You cannot delete the file physically since it leaves a digital memory footprint that can land into the wrong hands. Even with a secure VM, your system may be at risk due to suspension or information migration.
To protect your Hypervisor from data leakage, you must use secure backup software with strict security tools.
Virtualized environments are not immune to external threats; that is why you need to exercise caution to prevent unpredictable cyberattacks. Your Hyper-V will be more secure if you protect the entire virtual environment. Furthermore, ensure that you purchase an efficient VM backup software from a reliable vendor to minimize security risks.
