Examples of Trustworthiness Methods are :
• Fire extinguisher : a tool and a Trustworthiness Safety Method .
• CO2 fire suppression system 1 : a tool and a Trustworthiness Resilience Method ( the main purpose is to protect the system rather than the environment or humans ; CO2 is indeed dangerous for humans ).
• Network firewall : tool and a Trustworthiness Security Method .
• Melt-resistant steel : technology and a Trustworthiness Resilience Method .
• Windmill Restart : operational procedure for airplanes during an engine flameout and a Trustworthiness Resilience Method 2 .
• Electric motor brush replacement : operational procedure and a Trustworthiness Reliability Method .
• Brushless motor : technology and a Trustworthiness Reliability Method .
• Encryption of all social security numbers on servers : management directive and a Trustworthiness Privacy Method .
Examples of Trustworthy Methods assigned to several trustworthiness characteristics are :
• Fire-resistant plastic : technology and a Trustworthiness Safety / Resilience Method : it prevents a fire from spreading and endangering humans ( safety ) but also prevents the system itself from damage ( resilience ).
• Using encrypted hard disks : management directive and a Trustworthiness Security / Privacy Method .
Most of these Trustworthiness Methods for Industry IoT systems have existed for many years ; the only novelty being the assignment to one or more of the trustworthiness characteristics and the addition of a new name .
In the world of IoT systems there is typically a differentiation between IT ( Information Technology ) and OT ( Operational Technology ) and the merge of both is called IT / OT convergence ; the concept has been frequently addressed in several IIC documentations including a reference to trustworthiness [ 3 ], see Figure 3-1 . This IT / OT convergence brings technology from IT ( for example computer networks , databases , or cloud services ) into OT , which is addressing a world of physical execution ( like building products in an assembly line or mining ore ), unknown in the IT world . 1
