"Despite enhancements to aviation security since September 11, 2001, there remain vulnerabilities from employees at airports. This threat results from airline/airport employees that have access to sensitive and restricted areas during the normal course of their required duties. This thesis evaluates the threat and the measures in place to prevent attacks from aviation insiders. In addition, it evaluates a measure commonly referred to as 100 percent employee screening. Finally, the thesis derives recommendations to enhance the current methods to reduce the vulnerability, as well as proposes additional measures to further reduce the threat from aviation insiders."
