THE TRUSTWORTHINESS FOUNDATION

The Industrial Internet Reference Architecture designated five key system characteristics to support a system ’ s business purpose and to ensure that functions perform adequately without compromise . This was taken up in the Industrial Internet Security Framework , leading to their combination into a single property : trustworthiness .
“ Trustworthiness is the degree of confidence one has that the system performs as expected . Characteristics include safety , security , privacy , reliability and resilience in the face of environmental disturbances , human errors , system faults and attacks .”
Contemporaneously , the National Institute of Science and Technology ( US ) also introduced the term based on the same characteristics .
In addition to the trustworthiness characteristics , IIC also specified four groups of threats that endanger a trustworthy system : environmental disturbances , attacks , human errors and system faults . Threats can result in hazards that can lead to loss , which we wish to avoid .
Especially in industrial internet of things ( IIoT ) systems . This motivates further development of the concepts , especially as IIoT systems are connected to other systems that potentially were built with different trustworthiness requirements . Connected systems introduce risks to each other , so a single system cannot effectively be trusted until the other systems to which it is connected are also trusted .
The well-known “ Jeep Hack ” provides a vivid example of failures of trust in aggregated systems . This hack allowed near-total remote control of an ordinary consumer vehicle , a 2015 Jeep Cherokee . It illustrates how alignment of assumptions about the operational context is necessary
