Profiling is mainly based on methods first deployed in Israel by the national airline and a number of security companies. The nature of the methodology is proactive and aims to recognize criminal and terrorist activities at an early stage.
In practice, this means that our security officers use profiling to prevent or limit a possible threat before it develops in an attack or criminal activity. This includes a close observation of people being especially conspicuous or showing deviant behavior. Prevention is better than cure, both in terms of safety and cost.
