APPARATUS FOR MONITORING OTA ROM DATA AND METHOD THEREOF

An apparatus for monitoring OTA ROM data to monitor whether there is an abnormality in the OTA ROM data using data of a network switch and a method thereof are provided. A monitoring device monitors information about data communication of each of ports of a network switch, in a process where OTA ROM data is transmitted to an OTA update target controller in a vehicle through the network switch. A controller determines whether there is an abnormality in the OTA ROM data, based on the monitored information about the data communication of each of the ports and information about communication processed by the network switch in the process where the OTA ROM data is transmitted to the OTA update target controller, which is predefined. The stability of the OTA update is improved.
