Ensuring Security in Virtual Machine Environments

A virtual machine is a software-based emulation of a physical computer system. It allows multiple operating systems to run on a single physical computer by creating a virtual environment that simulates the hardware of a physical machine. This enables users to run different operating systems and applications on the same physical hardware without the need for multiple physical machines.

Virtual machines are commonly used for various purposes, such as software testing, development, and running legacy applications. They provide benefits such as increased flexibility, scalability, and cost savings by reducing the need for physical hardware. Virtual machines can be created and managed using virtualization software such as VMware, VirtualBox, and Microsoft Hyper-V.
