This chapter critically examines the role that the Internet and the Internet of Things (IoT) play in violent extremism. The chapter specifically focuses on arguments surrounding radicalisation as a pathway to terrorism and how individuals become radicalised due to different radicalisation processes and theories. Based on this critical analysis, the chapter argues that the Internet plays a key role in radicalisation to violent extremism due to several approaches. Issues highlighted in this chapter mainly focusses on the struggles of social media (SM) moderation and regulations. Furthermore, the chapter discusses how the IoT can aid SM regulation to reduce online radicalisation to violent extremism through artificial intelligence (AI) and machine learning (ML) technology. It will be argued how AI and ML could be deployed to reduce terrorist content online, making social media platforms (SMPs) a safer cyber space for individuals to operate within.
