Abstract
A monitoring apparatus includes a storage unit, a reception unit, a collation information generation unit, and a response unit. The storage unit stores a criterion for determining normality of a frame transmitted from a first electronic device. The reception unit receives the frame from a bus network. The collation information generation unit generates, when the reception unit receives a frame of a first identifier (ID) transmitted from the first electronic device, collation information which is information for collation with the criterion stored in the storage unit, based on the frame. The response unit transmits, when the reception unit receives a frame of a second ID transmitted from the second electronic device, information which is based on the criterion stored in the storage unit and the collation information generated by the collation information generation unit and which enables a check whether the first electronic device is valid, to the second electronic device.
