The sterile area is the section of an airport where screened passengers are separated from those who have not gone through the security screening process. This area is crucial for maintaining airport security as it ensures that only screened individuals have access to gates and boarding areas, minimizing the risk of security threats. The sterile area is subject to strict security protocols and is monitored to prevent unauthorized access, thus playing a vital role in the overall safety framework of airport operations.

The other areas mentioned do not specifically serve this function. The domestic terminal generally includes both screened and unscreened passengers, while the secure boarding room is an area prepared for those actively boarding flights; it does not provide the same comprehensive segregation as the sterile area. The public access zone, on the other hand, is open to all individuals regardless of their screening status, making it entirely separate from the controlled environment of the sterile area.
