Leibetseder, M: IT-Security and Virtualization

The implementation and use of Virtualization offers big advantages. The virtualization technology has been proven by the use of actual products. Due to this technology and the security features, the and the implementation of a sensitive part of the IT infrastructure, a DMZ, is displayed. This book focuses on the security aspects of virtualization. With the installation of a virtual DMZ it is possible to use all the advantages of a virtual infrastructure. The aim of this book is to develop a system to implement a DMZ within a virtual infrastructure, which is at least as secure as a physical one. In order to understand the virtualization technology the theoretical basics are described. Based on the features and functions of the virtualization products the VMWare Virtual Infrastructure 3 was chosen to implement the virtual DMZ. The security measurements and the comparison of the virtualized environment and a physical environment are discussed. Various Advantages and disadvantages of the configurations and types of a virtual DMZ are listed. Based on these insights a system has been put in place, how a DMZ can be implemented within a virtual infrastructure.
