The present invention relates to a device and a method for monitoring resources in a full virtualization system, the device and method generating a file table by parsing file information, generating a memory table when a memory is allocated, and then determining whether to execute a command by a process unit with reference to the file table and the memory table when the command is generated from a guest operating system or an application such that a virtual machine monitor is requested to execute the command.

Device and method for monitoring resources in full virtualization system

The present invention relates to a technology that performs: checking an integrity of a paravirtualization agent before executing the paravirtualization agent; protecting the paravirtualization agent by obstructing the modulation of a memory region to which the paravirtualization agent is allocated; when file input-output is generated in the paravirtualization agent, transmitting information associated with the generated file input-output to a host-based file system protection service to inquire about accessibility; determining an authority for access to the generated file input-output through a reasoning engine in the host-based file system protection service; and transmitting a result of the determination to the paravirtualization agent, and processing the generated file input-output, thereby protecting a file in a file system.
