Claim 9:
10. An information processing method executed by a processor included in an information processing apparatus, the information processing apparatus being connected to one or more vehicles and a threat information server via a network, the threat information server storing at least one piece of threat information, each of the at least one piece of threat information indicating an attack on a vehicle and a resolution state to the attack associated with each other, the information processing method comprising the steps of:
obtaining a detection result of an attack on one of the one or more vehicles connected to the information processing apparatus;
(i) determining whether the attack indicated by the detection result is included in any one of the at least one piece of threat information stored in the threat information server;
(ii) when the attack indicated by the detection result is included in any one of the at least one piece of threat information, determining whether the resolution state to the attack indicated by the detection result included in the one of the at least one piece of threat information indicates that the attack has not been resolved or indicates that the attack has been resolved;
deciding a processing priority level of the attack indicated by the detection result, based on a determination result obtained in step (i) and a determination result obtained in step (ii); and
outputting the processing priority level decided,
wherein in the deciding:
the processing priority level of the attack indicated by the detection result is decided to be a first priority level when the attack indicated by the detection result is not included in any of the at least one piece of threat information; and
when the attack indicated by the detection result is included in the one of the at least one piece of threat information:
the processing priority level is decided to be a second priority level lower than the first priority level in the case where the resolution state to the attack indicated by the detection result included in the one of the at least one piece of threat information indicates that the attack has not been resolved; and
the processing priority level is decided to be a third priority level lower than the second priority level in the case where the resolution state to the attack indicated by the detection result included in the one of the at least one piece of threat information indicates that the attack has been resolved.
