What is a virtual machine and how does it differ from a physical server or machine?
A virtual machine (VM) is a software emulation of a physical computer that allows multiple operating systems (OS) to run on a single physical server or machine. It provides an isolated and self-contained environment in which an OS, along with its applications and services, can be installed and executed. A VM operates as if it
What role do virtual machines play in security architecture and how do they provide isolation?
Virtual machines (VMs) play a crucial role in security architecture by providing a robust and effective mechanism for isolation. In the context of computer systems security, isolation refers to the separation of different components or processes to prevent unauthorized access, interference, or data leakage. By leveraging virtualization technology, VMs enable the creation of multiple isolated
What are some potential issues with virtual machines (VMs) that can introduce security vulnerabilities?
Virtual machines (VMs) are widely used in the field of computer systems security to provide a secure and isolated environment for running applications and testing software. However, there are several potential issues with VMs that can introduce security vulnerabilities if not properly managed. In this answer, we will discuss some of these issues and provide
