ConnecFvity  Standards  &  Security  

•  Requirements  for  Core  ConnecFvity  Technology:  – be  an  open  standard  with  strong  independent,  internaFonal  governance,  such  as  IEEE,  IETF,  OASIS,  OMG,  or  W3C,  

– be  horizontal  and  neutral  in  its  applicability  across  industries,
