Abstract
Provided is an anomaly detection method implemented by a computer, the anomaly detection method including identifying a time period during which time-series data of a parameter relating to a network have a periodicity, when a first time is within the time period, determining whether the network has an anomaly using a first method based on the time-series data, and when the first time is not within the time period, determining whether the network has an anomaly using a second method different from the first method.
