Abstract: An information processing device includes: a guest OS; a host OS that accesses a sector group stored in an external storage device in response to an access request from the guest OS; a virtualization control system that is executed on a hardware and controls execution of the guest OS and the host OS. The host OS includes: a back-end device driver that obtains the access request from the guest OS; and a sector group access determiner that determines whether or not the access request is anomalous, based on a sector group access rule database indicating a rule for accessing the sector group stored in the external storage device.
