PROBLEM TO BE SOLVED: To enable a check as to whether a memory protection device for detecting memory access having no access authority operates normally.SOLUTION: An information processing device includes: a memory; a system program for executing plural tasks each of which accesses the memory; a processor for executing the system program; and a memory protection device that, when a task accesses, from the processor using its authority, an area of the memory of which access authority is not provided to the task, detects the access as memory protection violation. The processor uses the authority of the task to intentionally access the area of the memory of which access authority is not provided to the task, by executing the system program, and determines whether the memory protection device has detected memory protection violation through the access. |
