Method for the Protection Against Cavitation in Cyber Attacks and Unit for Carrying Out the Method

A method and device for protecting a flow-conducting device of an installation against cavitation initiated by cyber attacks. At least one signal relating to an operating state of the installation is evaluated by an evaluation unit in order to detect a cyber attack by comparison with at least one reference value. If the evaluation unit detects a willfully brought-about irregular operating mode of the installation based on the evaluation, the unit passes on signals to components of the installation to bring about an installation operating mode which is in compliance with regulations and during which generation of cavitation is avoided, and produces a state in which the flow-conducting device is protected against the current cyber attack and/or against future cyber attacks.
