Virtualization has streamlined IT processes by reducing costs, minimizing downtime, and offering a sustainable approach. It has also made server utilization more efficient, eliminating the need for physical hardware. While IT teams are increasingly turning to virtualization, securing virtual machines (VMs) and hypervisors is also becoming a necessity.
Adopting effective virtualization security is as important as the smooth operation of virtual machines. According to sources, the virtualization security industry is valued at $2.5 billion in 2025, which is expected to surpass $5.3 billion by 2030. Such numbers show the growing demand for virtualized security. However, several IT teams still struggle with securing their virtual machines.
In this blog, we’ll learn about the virtualization security best practices and understand what ignorance can cause. Firstly, let us learn what virtualization security is and which elements create hurdles in it…
What is Virtualization Security?
Virtualization security is the methodology for securing virtualized IT environments and components, including virtual machines, hypervisors, and other components, against vulnerabilities. Virtualized systems generally include high-value access, centralized control, and sensitive datasets, enabling IT processes to operate smoothly.
Attackers often target virtual servers to exploit these elements and cause damage to IT teams. Hence, securing virtualization elements is crucial for companies aiming to protect their servers from threats. So, virtualization security involves implementing advanced firewalls to safeguard various components of virtual systems and tools.
Common Virtualization Security Threats:
Virtual Machine (VM) Sprawl:
Virtual machine sprawl occurs when VMs face uncontrolled spread, are left abandoned and unpatched, and sensitive systems are left exposed. These lead to data breaches and unauthenticated data access.
Misconfigurations:
VM settings with incorrect configurations can cause vulnerabilities and possibilities of attacks. It becomes easier for attackers to break into virtual systems with misconfigured settings and steal data easily.
Hypervisor Attacks:
Hypervisors generally monitor VMs. So, weaknesses in hypervisors can lead to granting unwanted access to attackers across virtual machines and other elements of virtualization.
Inefficient Isolation:
Isolation is a core stage of virtualization. If security is compromised during isolation or the process is not efficient enough, attackers can gain unauthorized access to the servers at any time.
Virtualization Security Best Practices to Consider:
A] Implement Advanced Network Security:
Securing networks is a priority while protecting virtual systems and components. As one of the virtualization security best practices, it enables secure communication between VMs, hypervisors, and other elements, safeguarding transferred messages, files, and information. Here are the aspects to look after when securing the network-
- Initiate network segmentation and micro-segmentation.
- Adopt distributed firewall guidelines.
- Protection of virtual private networks (VPNs).
- Integrate zero-trust networking.
B] Initiate Virtual Machine and Hypervisor Hardening:
Hardening VMs and hypervisors will limit exposure to probable risks and attacks, alongside reducing security issues by 85%. While hardening security for VMs and hypervisors, companies need to consider-
- Implement security patches appropriately.
- Utilize unified extensible firmware interface (UEFI) secure boot.
- Strengthen the isolation management framework.
- Appropriate security configuration processes.
C] Adopt Robust Identity and Access Management:
Role-based access and identity management are necessary for securing virtualized frameworks. In this regard, privileged accounts get access to hypervisor and virtual machine administration. The key measures to look after while adopting identity and access management approaches-
- Integrate multi-factor authentication for layered security.
- Adopt privileged access management.
- Initiate group-based authentication.
D] Integrate Effective Backup and Disaster Recovery Strategies:
Creating backups and strategizing disaster recovery helps IT teams recover from attacks quickly. Though the stolen data can lead to unwanted situations, backups can help in eliminating process disruption. Major considerations for this purpose-
- Adopt a framework for continuous backups.
- Secure backup data with passwords.
- Train the workforce for disaster management.
- Validate and test the data restoration process.
E] Conduct Continuous Audit and Monitoring:
Regular monitoring and auditing make anomaly detection easier in the virtual system. It is one of the virtualization security best practices that strengthens the robustness of virtual activities. It offers advanced visibility into the security posture and offers opportunities for improvement. Core aspects to consider are-
- Appropriate resource utilization.
- Track virtual machine activities.
- Audit data virtual machine accessibility.
- Evaluate system changes.
Concluding Remarks!
Solidifying virtualization security requires strategic planning, the availability of the right tools, and the necessary budget. The implementation of the entire process will further need significant time. However, virtual environments are vulnerable to hazardous threats. Companies and their IT teams need to adopt robust security frameworks for smooth and risk-free operations.
