Cyber-physical systems are characterized by an IT infrastructure controlling effects in the physical world. Attacks are intentional actions trying to cause undesired physical effects. When process data originating in the physical world is manipulated before being handed to the IT infrastructure, the data security property called "veracity" or trustworthiness will be violated. There is no canonical IT security solution guaranteeing that the inputs from a sensor faithfully represent reality. However, the laws of physics may help the defender to detect impossible or implausible sensor readings.
