1. An in-vehicle electronic system mounted to a vehicle, the in-vehicle electronic system comprising:
one or more sensors used to determine a security state of the vehicle, the one or more sensors being at least one of a door switch to output a signal indicating an open-close state of a door of the vehicle or a hood switch to output a signal indicating an open-close state of an engine hood of the vehicle;
an alarm apparatus configured to issue an alarm when the security state is abnormal; and
a first electronic control unit (ECU) that is a slave ECU connected to a core ECU and directly connected to the one or more sensors and the alarm apparatus without intermediation of any ECU, wherein
the first ECU is further connected to other slave ECUs and provided between the core ECU and the other slave ECUs, and has a gateway function for relaying communication between the core ECU and the other slave ECUs, and
the first ECU includes a processor configured to determine a security state based on at least information received from the one or more sensors, and cause the alarm apparatus to operate when the security state is determined to be abnormal.
