NextGen flight security risk assessment information concept

One of the foundational elements of the Next Generation Air Transportation System (NextGen) Secure Airspace concept is the flight security risk assessment. This risk assessment is continually performed and updated based on changes to security-related information pertaining to a particular flight, as well as changes to the security environment external to the flight; e.g., other flights, airports, and airspace. This dynamic risk assessment is part of the NextGen layered, adaptive security concept in which technologies, policies, and procedures are adaptively scaled and deployed to counter a particular threat. This paper describes key information concepts for dynamic flight security risk assessment.
