1. An apparatus for monitoring over-the-air (OTA) read-only memory (ROM) data, the apparatus comprising:
a monitoring device configured to, based on the OTA ROM data being transmitted to an OTA update target controller in a vehicle through a network switch, monitor a traffic measurement value of each of one or more ports of the network switch;
a storage configured to, based on the OTA ROM data being delivered to the OTA update target controller, store information regarding communication processed by the network switch, the OTA ROM data being predefined; and
a controller configured to determine a presence of an abnormality in the OTA ROM data, based on the monitored traffic measurement value of each of the one or more ports and the information stored in the storage, and
wherein the controller is configured to:
determine reference traffic for each port based on the information regarding communication processed by the network switch; and
determine a presence of an abnormality in data packet traffic of each of the one or more ports by comparing the traffic measurement value and the reference traffic to thereby determine the presence of the abnormality in the OTA ROM data.
