Abstract
Provided is an analysis device that is capable of easily detecting, by using only communication data, a change in another communicatively connected communication device, or a change in a configuration of a communication network that is connected to the other communication device. First communication feature information that has been generated based on communication data over a predetermined time period with another communication device that is connected to the communication network, and second communication feature information that has been generated based on new communication data over a predetermined time period with the other communication device that is connected to the communication network, are compared to determine the presence or absence of a similarity in the communication feature information. A determination result indicating the presence or absence of a change relating to the communication network is output based on the presence or absence of the similarity.
