Virtualization Vulnerabilities
Virtualization allows multiple virtual machines (VMs) to run on a single physical server, optimizing resource utilization, enhancing flexibility, and streamlining IT operations. However, like any technology, virtualization also introduces vulnerabilities that require careful consideration to ensure the security and stability of systems. This section explains the vulnerabilities associated with virtualization and the strategies to mitigate these vulnerabilities. These include the following:
- VM escape: While virtualization is designed to isolate VMs, the hypervisor (that is, the essential software managing these VMs) introduces an unexpected challenge. It can unintentionally create a path for lateral movement, known as moving east to west, and enable potential attackers to move from a secluded VM to the host system or other interconnected VMs. Vulnerabilities within the complex code of the hypervisor can serve as an avenue for unauthorized data...
