Abstract

A device and a method for anomaly detection in a communications network, at least two messages at a port of the communications network being observed, a property of a communication behavior of a network user being determined as a function of the at least two messages, a deviation of the property from an expected property being determined, and the presence of an anomaly being detected when the deviation differs from an allowable deviation. The expected property defines a communication behavior of the at least one network user as a function of an in particular static network architecture of the communications network.
