Learning Proxmox VE

Overview of this book

Proxmox VE 4.1 provides an open source, enterprise virtualization platform on which to host virtual servers as either virtual machines or containers. This book will support your practice of the requisite skills to successfully create, tailor, and deploy virtual machines and containers with Proxmox VE 4.1. Following a survey of PVE's features and characteristics,this book will contrast containers with virtual machines and establish cases for both. It walks through the installation of Proxmox VE, explores the creation of containers and virtual machines, and suggests best practices for virtual disk creation, network configuration, and Proxmox VE host and guest security.Throughout the book, you will navigate the Proxmox VE 4.1 web interface and explore options for command-line management

Aggravated vulnerabilities


Virtualization's potential security benefits are certainly compelling, but many are quite conditional and altogether they are certainly no panacea.

Moreover, virtualization introduces new threats to an infrastructure—threats that otherwise either wouldn't be a concern at all or are exacerbated by virtualization.

This section calls attention to vulnerabilities that are historically problematic for virtual infrastructures:

  • Denial of service attacks
  • VM escape and hyper jumping
  • Server sprawl
  • Growing complexity

Denial of service attacks

Denial of service (DoS) attacks come in a wide variety of flavors. However, the immediate intent is the same: overwhelming a network, and its administrators, by generating large amounts of illegitimate traffic.

Distributed denial of service (DDoS) and DoS attacks are cheap, effective, and increasingly common. On the surface, they seem to be most effective at rendering services unavailable or unusable. More insidious, perhaps, is that, by keeping...
