  • Patent number: 12177239
    Abstract: An attack analyzer includes: a security log acquisition unit acquiring a security log including an abnormality detection signal generated by a security sensor mounted on an electronic control device constituting part of an electronic control system and indicating that the security sensor has detected an abnormality; an alive signal acquisition unit acquiring an alive signal; a prediction table storage unit storing a prediction table showing a correspondence relationship between a predicted attack route in the electronic control system and a predicted abnormality detection signal predicted to be generated by the security sensor; an attack route estimation unit estimating, using the prediction table, the attack route of an attack received by the electronic control system from the abnormality detection signal and the alive signal included in the security log; and an attack information output unit outputting attack information indicating the attack route.
