1. A system for a vehicle, the module comprising:
a first electronic control unit (ECU) that transmits and receives first data to and from a first in-vehicle module in the vehicle;
a second ECU that transmits and receives second data to and from a second in-vehicle module in the vehicle; and
a control circuit that controls relay of third data among the first ECU and the second ECU,
wherein the control circuit determines whether reception data received by the control circuit from the first ECU or the second ECU is unauthorized,
the control circuit determines whether a traveling state of the vehicle satisfies a predetermined condition in response to the reception data being unauthorized,
the control circuit stops relaying the third data in response to the reception data being unauthorized and the traveling state of the vehicle satisfying the predetermined condition, and
the traveling state of the vehicle, for satisfying the predetermined condition, includes at least one of (a) the vehicle being stopped, (b) a vehicle speed being at or below a predetermined speed, (c) brakes being applied, (d) a hazard indicator being on, (e) a driver being in a state capable of driving, or (f) self-driving functions being in an off state.
