Virtualization Security refers to the practices and technologies implemented to protect virtualized environments, which are fundamental components in modern IT infrastructures. In virtualized environments, multiple virtual machines (VMs) operate on a single physical host, sharing hardware resources while maintaining logical separation.
Key aspects of virtualization security include:
Hypervisor protection: The hypervisor (virtualization layer) must be hardened against attacks since compromising it could affect all hosted VMs. Regular patching and configuration hardening are essential.
VM isolation: Ensuring strong boundaries between VMs prevents unauthorized access or data leakage between environments. This includes memory isolation and network segregation.
Resource management: Preventing resource exhaustion attacks where one VM consumes excessive resources, causing denial of service to others.
Snapshot management: VM snapshots contain sensitive data and must be secured. Proper encryption and access controls for snapshots prevent unauthorized exposure.
VM escape protection: Implementing safeguards against VM escape attacks where malicious code breaks out of a VM to access the hypervisor or other VMs.
VM sprawl management: Tracking and securing all VMs, including dormant ones, to prevent unauthorized access or outdated, vulnerable systems.
Network virtualization security: Securing virtual networks through proper segmentation, virtual firewalls, and intrusion detection systems.
Storage virtualization protection: Securing virtualized storage through encryption, access controls, and monitoring.
Virtual Desktop Infrastructure (VDI) security: Protecting virtualized endpoint environments through endpoint protection, access controls, and secure connection protocols.
Orchestration security: Securing the automation and management tools used to deploy and manage virtual environments.
Compliance considerations: Ensuring virtualized environments meet applicable regulatory requirements through proper documentation and controls.
