Exploring Security Countermeasures along the Attack Sequence

A systematic method exploring security countermeasures is proposed. For each attack, one can consider the moments along the time sequence of the attack, and for each of the moments, one can define approaches of countermeasure design against the attack that is effective at the moment. One could extract new approaches from the existing counter-measures, and think of new countermeasures based on the new approaches against other threats and attacks.
