Ben-Gurion International Airport implemented a security concept during Operation Protective Edge to protect the airport from rocket attacks by Hamas. The security division operates under the airport managing director and is responsible for preventing attacks on aircraft, in the airport grounds, and admitting explosives. The security concept combines human security officers and advanced technologies. It uses security circles and zones, as well as automated foreign object detection on runways to maintain airport operations during threats of rocket attacks. During Operation Protective Edge, over 4,000 rockets were fired at Israel but none struck the airport grounds, allowing airport activities to continue without interruption.
