Prevention of Terrorism Attacks by Identifying Terrorist Activities

Terrorism causes material and non-material losses for affected victims of that attack. Victims of terrorist attacks are not only immediate victims, but also indirect victims. Terrorist attacks can be prevented if terrorist activities are identified in advance. This research differs from previous studies because it identifies terrorist activities before the attack. People's attention to safety in their environment can also play a role in anticipating terrorist attacks. Based on chronology with a chronological analysis, it is possible to know that the perpetrators conducted a survey on the target of the attack. In conducting surveys, the perpetrators will be disguised, so to look ordinary, and exploit the negligence of officers. Acts of terrorism can be prevented by raising security concerns about suspicious activities terrorists conducted before the attack, and by keeping the pace and addressing terrorism issues at both national and international levels.
