Emerging Trends in ICT Security

In this chapter we present European law enforcement agency research designed to tackle the risk and harm posed to citizen safety from online radicalization following a terrorist event. This research provides a framework to tackle social media radicalization and addresses the need for: (a) a stronger online citizen and community presence to counter harmful narratives; (b) support for the identification and training of community credible voices to help prevent online radicalization and; c) increased collaboration between law enforcement agencies, leading to the development of new and innovative ways to prevent citizens from adopting violent extremist perspectives.
