Claim 0:
1. A security processing method, executed by a computer, for counteracting an anomalous frame transmitted on an on-board network of a single mobility entity, the on-board network of the single mobility entity joining multiple electronic control units installed inside the single mobility entity, the multiple electronic control units performing communication of a frame inside the single mobility entity, the security processing method comprising:
assessing, by the computer, based on first information about multiple frames received on one or multiple on-board networks of one or multiple mobility entities and second information about the frame received on the on-board network of the single mobility entity after the multiple frames are received on the one or more multiple on-board networks of the one or multiple mobility entities, an anomaly level of the frame received on the on-board network of the single mobility entity, the anomaly level of the received frame being a degree to which said received frame is considered to be anomalous; and
deciding whether or not to transmit a first alert to the single mobility entity based on the anomaly level, and deciding whether or not to transmit a second alert to a manufacturer of the single mobility entity or a security provider based on the anomaly level,
wherein the computer differently decides whether to transmit the first alert and the second alert for at least one anomaly level.
