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 in the United States 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 .
