The era of Internet of Things (IoT) is currently being ushered in. IoT is a combination of various networking and computing technologies that heralds a new age of data aggregation and ubiquitous connectivity among physical objects. However, most of the cyber threats emanating from this remain unsolved and may have huge impact on our lives. One of the possible major changes in the impact landscape is the imminent physical results of cyber threats as IoT technologies enable closer interactions between humans and information systems. Although the cyber threats to critical infrastructures have been widely considered by the cyber security community, cases of catastrophic physical impacts are rare which means the impact posture has not yet shifted from information centric impacts to physical ones. However, widespread use of IoT technologies has the potential to accelerate this shift which may bring the threat of cyber terrorism into the picture. This paper provides a preliminary comparison of a typical IoT application in the area of health with an industrial control system (ICS) in order to show that IoT applications require careful consideration as terrorists may attack them with easy-to-implement cyberattacks for the purpose of creating physical harm.
