In recent decades, security institutions have placed high priority on understanding the relationship between radicalization, violent extremism, terrorism, and the use of both traditional and new media tools. The terrorist attacks of 9/11 brought global attention to terrorism and its cross-border impact, but the use of information and communication technologies (ICT) by terrorist groups has increasingly become a crucial aspect of terrorism.
