Abstract: An information processing device includes a guest OS and a host OS that accesses a sector group in response to an access request from the guest OS. The host OS includes: an access log analyzer that generates, by reference to a sector-group database, a sector-group access log from the access request; a sector-group access determiner that determines, based on the sector-group access log, whether the access request seeks to access the sector group related to an application; and a manager that updates, based on a developer definition policy, a sector-group access rule database and the sector-group database if it is determined that the access request seeks to access the sector group and the guest OS makes a change to an application storage area.
