Access Control Enforcement in IoT: state of the art and open challenges in the Zero Trust era
Abstract
Zero Trust (ZT) is a security paradigm which is nowadays finding application in different domains. One of the domain that can most benefit from ZT is represented by Internet of Things (IoT), where huge quantity of personal and sensitive data are continuously generated by IoT devices, which, in the recent years, have been the target of several security attacks. In this paper, we identify a set of access control requirements which are expected to enable the adoption of ZT in the IoT domain. Through the analysis of state of the art access control approaches currently employed in IoT ecosystems, we observe the lack of solutions capable of addressing all the identified requirements. We therefore discuss significant open challenges that still need to be addressed in this area.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
