Perimeter Security Post 9/11

Although much of the attention regarding airport security has been focused on passenger and baggage screening, perimeter security also is a critical factor in mitigating terrorist threats. This article describes the perimeter security enhancements put into place at the Dallas Fort Worth International Airport (DFW). Providing adequate security to the 18,000 acre facility requires airport and law enforcement officials to balance vulnerabilities, threats, operational considerations and fiscal constraints. Immediately after the 9/11 attacks, DFW took steps to limit airport access by closing unnecessary aircraft operation area gates and requiring employees to go through passenger screening checkpoints. The airport then used a holistic approach in soliciting input and coordination with all appropriate stakeholder partners to develop a comprehensive security plan. A three-phased approach was developed to improve fencing and barricades and to mount cameras for enhancing remote surveillance capabilities. The airport also installed post and cable obstructions to prevent vehicles from evading vehicle inspection points. Currently, DFW is testing biometric technology to determine the most efficient and effective employee access control system.
