IoT Hardware‐Based Security: A Generalized Review of Threats and Countermeasures
Catherine Higgins, Lucas McDonald, Muhammad Ijaz Ul Haq, Saqib Hakak · 2021
Security in the Internet of Things (IoT) is paramount as the number of IoT devices are on the rise and new applications are emerging. This chapter presents different types of hardware attacks and highlights the countermeasures to mitigate such attacks. The taxonomy of the attacks is presented. These threats are divided into three main categories, which are Hardware Design threats, Side Channel attacks, and Node Level threats. In side-channel attacks, the devices reveal sensitive information unintentionally in a number of ways. The physical state of electromagnetic emission, power consumption, sound, and timing values are all examples of how devices leak information, side-channel attacks exploit these vulnerabilities. Security best practices should continually be followed and evaluated as the threat to IoT devices is continually changing. To conclude, it is important to keep in mind that attacks are constantly evolving and new types of attacks altogether in the future will emerge.
