Abstract

In today's interconnected world, where most devices are connected to the internet and constantly sharing data, the increasing number of IoT devices presents challenges for large companies to develop secure IoT systems.. With the progression of interconnected systems, the risk of hampering security is also a big concern. In the current scenario, it is very easy for attackers to initiate any kind of security breach. The attack will be either on its software, firmware, or hardware level. This chapter deals with the hardware security of the IoT system, which is also termed physical security. Various security threats related to the physical security of an IoT device are described. Various consequences have been mentioned that can occur due to these attacks. With these physical attacks, a lot of severe loopholes can be created in the current ongoing research and development of these interconnected systems.
