Securing virtual environments for VMware, Citrix, and Microsoft hypervisors

Virtualization changes the playing field when it comes to security. There are new attack vectors, new operational patterns and complexity, and changes in IT architecture and deployment life cycles. What's more, the technologies, best practices, and strategies used for securing physical environments do not provide sufficient protection for virtual environments. This book includes step-by-step configurations for the security controls that come with the three leading hypervisor–VMware vSphere and ESXi, Microsoft Hyper-V on Windows Server 2008, and Citrix XenServer. Includes strategy for securely implementing network policies and integrating virtual networks into the existing physical infrastructure Discusses vSphere and Hyper-V native virtual switches as well as the Cisco Nexus 1000v and Open vSwitch switches Offers effective practices for securing virtual machines without creating additional operational overhead for administrators Contains methods for integrating virtualization into existing workflows and creating new policies and processes for change and configuration management so that virtualization can help make these critical operations processes more effective

Hacker’s Challenge : Test Your Incident Response Skills Using 20 Scenarios

Mike Schiffman has hit upon a great formula for Hacker's Challenge. Rather than try to research, fully understand, and adequately explain attacks that have taken place on other people's networks–the approach taken by too many writers of books about computer security–Schiffman lets network administrators and security experts tell their stories first-hand. This is good. What's better is that Schiffman has edited each of their war stories into two sections: one that presents the observations the sysadmin or security consultant made at the time of the attack, and another (in a separate part of the book) that ties the clues together and explains exactly what was going on. The challenge in the title is for you to figure out what the bad guys were doing–and how best to stop them–before looking at the printed solution. Let's call this book what it is: an Encyclopedia Brown book for people with an interest in network security.

It doesn't really matter, from a value-for-money standpoint, whether your skills are up to the challenge or not. The accounts of intrusions–these are no-kidding, real-life attacks that you can probably learn from, by the way–are written like chapters from a novel (though log file listings, network diagrams, and performance graphs appear alongside the narrative text). Recall every time you've seen a movie or read a book with computer scenes so technically inaccurate they made you wish for a writer with a clue. Schiffman and Hacker's Challenge is what you wished for. –David Wall
