Abstract:
Cyber physical systems are technical systems that are operated and controlled using information and communication technology. Protecting the integrity of cyber physical systems is a highly important security objective to ensure the correct and reliable operation and to ensure high availability. A comprehensive protection concept of the system integrity involves several axes: the component level ranging from sensors/actuator devices up to control and supervisory systems, planning and configuration management, and the system life cycle. It allows detecting integrity violations on system level reliably by analyzing integrity measurements from a multitude of independent integrity sensors, capturing and analyzing integrity measurements of the physical world, on the field level, and of control and supervisory systems. Trusted sensors can be used as add-on in existing industrial automation and control systems to allow for cross-checking with sensor measurements of the control system.
