Human factors in layers of defense in airport security

Airport security systems are built up out of layers of defence based on the security-in-depth model (Talbot & Jakeman, 2008). The Transport Safety Authority (TSA) in the United States defined a staggering 20 layers of defence to control security risks. This means that not only security personnel is responsible for security at the airport but many others too. However, the perceptions vary between different users of airports so it is difficult to involve all airport users in the security process. This paper focuses on identifying these factors through surveys. Differences were found between the level of education, between employees and passengers, between job groups working in the airport for instance the perceived level of trust in technology used in airport security or the perceived level of safety in the airport.Values and TechnologyTechnology, Policy and Managemen
