Abstract
This chapter discusses some of the various virtual environments that can be run on portable devices such as thumb drives, iPods, and cell phones. The use of virtualization is growing in the individual use market, as many corporate organizations use devices such as the IronKey. Virtualized environments, especially those run from a removable drive, can make forensics investigation more difficult. Technological advances in virtualization tools can transform removable media into a portable personal computer (PC) that can be carried around in a shirt pocket or on a lanyard around a neck. Running operating systems (OSes) and applications in this fashion leaves very little evidence on the host system. Currently most portable environments save at least some part of the information in the system registry or configuration files. In “Portable Desktop Applications Based on P2P Transportation and Virtualization,” Zhang, Wang, and Hong propose an application that can work without installation by making a two-part application. One part is portable and enables the application to run in a sandbox where it can access and store the data associated with it, and the second part can run in an isolation mode. Other similar environments include Feather-weight Virtual Machine and Progressive Deployment System.
