Functional safety components protect life and health when working on plants and machinery. For instance, a safety locking function can prevent a safety gate to a hazardous zone of a plant or machine from being opened. To ensure that safety functions of control systems are reliable, the control system itself must also be secure, i.e. protected against tampering.
Safety components must therefore be
The annual State of IT Security Report of the German Federal Office for Information Security (BSI) shows how frequently specific attacs have been observed. The reports describe, for example, attacks on industrial controls capable of putting a blast furnace in a steel plant out of control or instances where a safety control system was hijacked in a chemical plant.
Protection against attacks is therefore imperative, especially for functional safety components.
The DGUV works towards an effective improvement of this situation in a number of different areas:
