Abstract: An apparatus is provided. The apparatus includes a detector configured to detect a state of the apparatus, and a processor configured to determine a current change degree of an apparatus state between a current point of time and a previous point of time based on a first change value of the apparatus state at the current point of time and a second change value of the apparatus state at the previous point of time earlier than the current point of time, and determine whether change in the apparatus state is normal or abnormal based on a result of comparison between the determined current change degree and an accumulated change degree of the apparatus state accumulated for a predetermined time section before the current point of time.
