A Smart-Farming Ontology for Attribute Based Access Control

With the advent of smart farming, individual farmers have started adopting the concepts of agriculture 4.0. Modern smart farms leverage technologies like big data, Cyber Physical Systems (CPS), Artificial Intelligence (AI), blockchain, etc. The use of these technologies has left these smart farms susceptible to cyber-attacks. In order to help secure the smart farm ecosystem in this paper, we develop a smart farming ontology. Our ontology helps represent various physical entities like sensors, workers on the farm, and their interactions with each other. Using the expressive ontology we implement an Attribute Based Access Control (ABAC) system to dynamically evaluate access control requests. Furthermore, we discuss various use cases to showcase our access control model in various scenarios on a smart farm.
