Good to see some other points of view on IoT security. This is one of =
the specific issues that triggered my joining this list!

I=E2=80=99ve been struggling to get the point over about authorisation =
transfer to various groups and found that they generally agree =
intellectually, but still seem to think in terms of authentication =
creating authorisation. Naming is another related issue. I=E2=80=99d =
concluded that Things in IoT shouldn=E2=80=99t be identified just with =
individual hardware objects, even though the model has value from a =
usability point of view (esp. when things go wrong). In fact, most =
current IoT devices are much too clever to easily compose and get useful =
compound behaviours out of.  The issue seems to be a tension between =
makers of Things and service providers who are more interested in the =
Internet aspects. The different interests create different motivations =
over features vs control (inc. security).

I=E2=80=99d be intrigued on points of view on privacy issues to do with =
aggregated data. All providers that I=E2=80=99ve worked encountered are =
salivating at mining behavioural and other data. So the question is, =
will general users get so spooked that they will only use well =
controlled systems or will they covet the functionality more. I=E2=80=99m =
pitching the former, but can see an argument for the latter. If the =
former is true, then I=E2=80=99ve concluded that the provider of the IoT =
service needs an opt-in policy for retaining any data. =
(Datensparsamkeit, as I=E2=80=99ve seen the approach described).
