摘要：
A bus monitoring security device is connected to a bus, which includes a tool side bus having a tool connection terminal and an ECU side bus. The ECU side bus is coupled with an ECU, and the tool side bus is coupled with a tool capable of communicating with the ECU via the tool connection terminal. The tool side bus and the ECU side bus are separately coupled with the bus monitoring security device. The bus monitoring security device includes: a controller for determining whether the tool being to access the ECU is connected to the ECU side bus, and for restricting transmission and reception of data between the tool and the ECU when the controller determines that the tool is connected to the ECU side bus.
