PROBLEM TO BE SOLVED: To solve the problem that it is necessary to stop a service, and that it is impossible to solve any threat to availability even when an OS detects any attack/intrusion after a process having fragility to any buffer overflow attack receives the buffer overflow attack. SOLUTION: A state just before an attack message is received is saved and stored, and when any attack/intrusion is detected, the state at the time of saving is restored. When the danger of any attack/intrusion is gone, or any state change making it difficult to restore the state is generated in a process, the saving and storage is stopped, and a warning state is released so that the overhead of the warning state can be relaxed.
