Abstract
An attack detection device includes: a receiver configured to receive messages that are periodically transmitted from a communication device in a network; and a processor. The processor predicts a number of messages to be received by the receiver in a specified monitor range based on a transmission cycle of the messages so as to generate a predicted value. The processor counts a number of messages received by the receiver in the specified monitor range so as to generate a count value. The processor detects an attack in the network according to a result of a comparison between the predicted value and the count value.
