Abstract(in English) In building automation and control systems (BACS), systems such as air conditioning, lighting, and disaster prevention are centrally managed using BACnet/IP. Recently, these systems are being connected to the Internet via Gateway, and there have been cases of crackers attacking buildings. The purpose of this paper is to analyze the impact of the network load caused by the increase in traffic in BACS, and to detect attacks that may become a load. Focusing on the increase in traffic caused by attacks, we propose the method for detecting anomalies by calculating the predicted value of traffic in units of time using the linear regression model. We also propose the method for notifying the administrator in case of an anomaly.
