Aman Srivastava, Ankita Agarwal · Zenodo (CERN European Organization for Nuclear Research) · 2021
This paper provides an overview of Internet of Things (IoT) and Operational Technology (OT) with an emphasis on major security challenges and attacks faced by these technologies. With increased deployment of IoT and OT systems in today's world, e.g., IoT is often seen in office or home automation and smart appliances, this increases the possibility of malicious threats than ever before. While a number of researches have been done to explore such challenges. Compared to previous work, this paper aims to provide a detailed analysis of security goals which covers common problems faced by IoT and OT devices, OWASP top 10 security threats, The Purdue Model, IT/OT convergence and addresses most of the important security attacks and their countermeasures for IoT and OT systems.
