US Patent 8407801 Security countermeasure function evaluation program

In a security countermeasure function evaluation apparatus, an estimator operates an input unit, whereby an evaluation point calculation unit makes an evaluation as to whether each item of countermeasure information representing a security countermeasure function in detail satisfies each item of sufficient condition table information, and the evaluation point is calculated from the evaluation result of each item, whereby the transition probability calculation unit calculates a transition probability based on the evaluation point.
