PROBLEM TO BE SOLVED: To detect unauthorized memory access which cannot be detected only by a memory protecting mechanism, and to present information, in a program execution environment. SOLUTION: When memory access is generated according to the execution of a program, an access object memory area is specified by collating an accessed memory address with the layout information of a memory area, and whether or not the memory access is authorized is decided by combining conditions such as the type (read or write) of access and the information of a thread and module related with the memory access, and the result is presented at a display device or the like.
