Method and system for using principal components analysis (PCA) to display trends in aircraft cyber events in real time

摘要

A system, method, and computer readable media for using principal components analysis (PCA) to graphically display cyber event information about an aircraft or fleet of aircraft. A ground-based security module collects historical cyber log data about the aircraft and performs PCA on the historical data to derive two principal components and their corresponding loading vectors. The loading vectors are transmitted to an air-based security module on the aircraft. The air-based security module collects real time cyber log data, computes numerical scores associated with the loading vectors on board the aircraft while the aircraft is in flight, and transmits the numerical scores to the ground-based module. The ground-based module graphically displays a comparison of the numerical scores to the corresponding loading vectors for the historical log data on a biplot to reveal trends in the cyber health of the aircraft.
