Scientists discovered Theft Protection for Virtual Machines
8 August 2011: Scientists have discovered the detect hacker attacks on virtual machines. Companies and government agencies that utilize virtual machines can protect the data stored in them against theft with the help of this machines.
Virtual machines are computers that incorporate no hardware and are totally simulated by software. Virtual machines are much more flexibly and efficiently utilizable than conventional computers, since, like all other types of software files, they may be rapidly transferred from one location to another with little effort. However, that particular feature harbors risks, since users will not notice unauthorized migrations out of their company's or government-agency's network due to hacker attacks. An entire virtual machine and all of the data stored on it may thus fall into the wrong hands within a few seconds.
