Trustworthiness is defined 1 by the Industry IoT Consortium ( IIC ) as the “ degree of confidence one has that the system performs as expected with characteristics including safety , security , privacy , reliability and resilience in the face of environmental disturbances , human errors , system faults and attacks ”.

One of the Trustworthiness characteristics , Resilience , is defined by the IIC as the “ ability of a system or component to maintain an acceptable level of service in the face of disruption ” 2 . The following more detailed definition is consistent with but goes further than the IIC definition :
“ A system is resilient if it can adjust its functioning prior to , during , or following events ( changes , disturbances , and opportunities ) and thereby sustain required operations under both expected and unexpected conditions ." 3 , 4
Change , errors , attacks , faults and disturbances create hazards for an organization that may need to be managed . Risk management is important for understanding consequences and having confidence in a system . Resilience is important for anticipating , addressing and learning from events in order to maintain confidence in the system and address concerns that cannot easily be
