Kind Code:
A1
Abstract:
[PROBLEMS] To provide an operating system capable of suppressing a computer virus and an unauthorized access utilizing the buffer overrun phenomenon which is said to be a cause of generation of a security hole, and a recording medium containing the operating system. [MEANS FOR SOLVING THE PROBLEMS] An operating system (100) provides an API (application program interface) or a system call to a program. The operating system (100) includes address acquisition means (5) for reading a storage address of the program in the memory device before executing the API or the system call requested from the program. When the program which has requested the API is defined to be a primary program and secondary to n-degree (n is an integer not smaller than 2) program as a call source of the primary program are defined to successively form call hierarchies if the primary program is a subroutine, the address acquisition means (5) acquires the storage address of the primary program and the storage address of the secondary to n-degree program.
