Abstract

A method for protecting a network having multiple network subscribers against a cyberattack, in which bits or bit sequences of a message are transmitted between the network subscribers in the network via different voltage levels on at least one transmission route of the network. For this purpose, at least one characteristic of the voltage levels or of the transmitted bits or bit sequences is actively modified in at least one of the network subscribers or on the at least one transmission route and the origin of the transmitted bits or of the at least one transmission route is determined on the basis of the at least one characteristic. The cyberattack on the network is detected or the cyberattack on the network is localized in the network as a function of the ascertained origin.
