Airport security The CISF is in charge of airport security at all commercial airports in India. Airport security, in the past, was under the control of airport police (under the relevant state government). However, following the hijacking of Indian Airlines Flight 814 in 1999, the topic of handing over security of the airports to the CISF was first proposed. While this proposal lay low for the next two years, the central government decided to respond to the security threat faced by all major nations of the world after the 2001 terrorist attacks happened in the United States (11 September 2001) and decided to adopt the suggestion. The Jaipur Airport was the first airport that came under the CISF's control on 3 February 2000. Following this, the majority of the commercial airports in India were brought under its purview. As of now CISF is protecting a total of 64 international and domestic airports in the country. Security for Delhi Metro Security on the Delhi Metro is handled by the CISF Unit Delhi Metro Rail Corporation of CISF, who have been guarding the system ever since they took over from the Delhi Police in 2007. Closed-circuit cameras are used to monitor trains and stations, and feed from these is monitored by both the CISF and Delhi Metro authorities at their respective control rooms. Over 3500 CISF personnel have been deployed to deal with law and order issues in the system, in addition to metal detectors, x-ray baggage inspection systems and dog squads which are used to secure the system. Intercoms are provided in each train car for emergency communication between the passengers and the driver. Periodic security drills are carried out at stations and
