Detecting Unauthorized Device Access by Comparing Multiple Independent Spatial-Time Data Sets from Other Devices

NASA’s Goddard Space Flight Center has developed a method to collect suspicious data and analyze them without extensive costs. A common challenge in complex computer systems is the identification of unauthorized use, which can be hackers accessing anything of interest after unauthorized access. This process combines various functional checks across devices, and specifically not in a common operating environment such that unwanted activities become more difficult for the unauthorized user to execute without easy detection.
