Researchers from the Horst Görtz Institute for IT Security at Ruhr-Universität Bochum, together with colleagues from the University of Chicago and the University of Washington, have investigated what access control for Internet-connected household appliances should ideally be like.
They interviewed 425 users in the USA about their preferences and derived suggestions for access management from these.
The team presented the results at the Usenix Security Symposium in the USA in August 2018.
Only admin and guest are provided
The researchers first analysed which smart home devices are currently on the market, what capabilities they possess, and how access rights to them can be managed.
"In rare cases, there is a guest group with other access rights in addition to the administrator or owner, who is allowed to do everything," summarises Maximilian Golla, doctoral candidate in the Bochum-based Mobile Security Research Group headed by Professor Markus Dürmuth.
