Cybersecurity in Internet of Things

Abstract

The Internet of Things (IoT), i.e. all Internet-connected devices that surrounding us, is estimated to exceed 25 billion by 2030. As the IoT now occupies a very wide area of our daily lives, security of these devices especially from cyberattacks is becoming a major issue. The research of this thesis will focus on the analysis of cybersecurity issues in the IoT, the threats and security vulnerabilities that arise, the proposed countermeasures and solutions from a cyber technical point of view, through various cybersecurity frameworks, models and methodologies. After all, due to the extremely wide variety and way of implementation of the hardware and software that is each IoT device carries, it is not possible to establish a default security policy or a single solution for all IoT devices, but it is possible to mitigate and address effectively the majority of cybersecurity issues, by classifying them into categories, analyzing them, and implementing to the IoT ecosystem the necessary countermeasures accordingly.
